Getting Started Using GuitarJack Model 2 with FourTrack or StudioTrack Plug a 1/4 inch and/or 1/8 inch connector into GuitarJack Model 2. Plug headphones into the 1/8" stereo/line out on the GuitarJack Model 2 - for best results do not use the headphone output on the iPhone/iPad/iPod touch.

Plug GuitarJack Model 2 in via the dock connector on the iPhone/iPad/iPod touch before launching a GuitarJack Model 2 enabled app like FourTrack, StudioTrack, GuitarTone, or Taylor EQ. The GuitarJack Model 2 control panel is located under Song Tools in those apps. The GuitarJack Model 2 control panel is where you can select a mode and set the input level before recording. The default input configuration, when GuitarJack Model 2 is first connected, uses the Instrument (1/4") input in Lo-Z mode for the left channel and the Mic/Line (1/8") input in Normal mode for the right channel.  This allows GuitarJack Model 2 to work well out of the box with most third party audio apps like other recording and amp apps, even if they don't have a GuitarJack Model 2 Control Panel. To change modes or set levels for GuitarJack Model 2 use with third party apps, configure the settings using an app with the GuitarJack Model 2 control panel (eg. FourTrack, StudioTrack, GuitarTone, or Taylor EQ, then quit to launch the third party app (see which apps you can use with GuitarJack Model 2). GuitarJack Model 2 will retain the current settings and levels even when the iOS device goes to sleep or GuitarJack Model 2 is disconnected.

See demo video: Using the GuitarJack Model 2 and GuitarJack Model 2 SongTools inside StudioTrack. The guide above and these frequently asked questions contain more tips.
Contact GuitarJack support with any questions.

Input Gain Control GuitarJack Model 2 allows you to adjust the analog input level for 60 dB of analog input gain (72 dB with the 12 dB pad) controlled with the GuitarJack Model 2 control panel, located under Song Tools in FourTrack and StudioTrack. Observe the metering in the GuitarJack Model 2 Song Tool to prevent clipping and set gain level appropriately.
Input Monitoring Input monitoring is on by default in FourTrack. The input signal can be heard through the 1/8" headphone output on GuitarJack Model 2 via the GuitarJack Model 2 Song Tool so you can adjust your input settings, but will be silent when you exit the GuitarJack Model 2 Song Tool. Arming a new track will begin monitoring in the headphones.
Using GuitarJack Model 2 with apps that do not have a GuitarJack Model 2 Control Panel GuitarJack Model 2 is compatible with many recording apps, guitar tuners, and audio effects apps, even if they do not have a GuitarJack Model 2 control panel. To change modes or set levels for use with third party apps, configure the settings using an app with the GuitarJack Model 2 control panel (FourTrack, StudioTrack, GuitarTone ($2.99), and Taylor EQ (free)), then quit to launch a GuitarJack Model 2 compatible third party app that does not have a GuitarJack Model 2 control panel. GuitarJack Model 2 will retain the current settings and levels. Sonoma is planning to prepare the GuitarJack Model 2 Control Panel SDK for third party developers, similar to the AudioCopy/AudioPaste SDK.

Stereo recording and simultaneous instrument and voice recording is currently possible while using GuitarJack Model 2 with FourTrack or StudioTrack, and other apps that support those features.
Compatibility

GuitarJack Model 2 FAQ Answers
  1. What is GuitarJack Model 2?

    GuitarJack Model 2 is currently out of stock in Sonoma's store. Check Amazon for availability. As an alternative, we recommend our newer product GuitarJack 2 USB, which is still in stock. Read about the differences between GuitarJack Model 2 and GuitarJack 2 USB.

    GuitarJack Model 2 is the best sounding and highest quality audio input and output interface for iPhone, iPad and iPod touch. (See GuitarJack 2 USB for Mac/Win/iPad.) Connect a wide range of instruments, microphones, and other audio hardware to the iPhone, iPad and iPod touch via 1/4" instrument and 1/8" stereo mic/line inputs. GuitarJack Model 2's 1/8" stereo line/headphone output offers increased drive for headphones. GuitarJack Model 2 features software controllable input level control with 60 dB of gain plus 12 dB pad for 72 dB of adjustment, software configurable Lo-Z and Hi-Z modes, a 24-bit AD/DA converter, and the highest quality sound. GuitarJack Model 2 can record in stereo and simultaneously record vocals and an instrument when used with apps like FourTrack and StudioTrack that support those features. Compare iPhone and iPad audio input and output interfaces.

    FourTrack ($4.99), StudioTrack ($9.99), GuitarTone ($2.99), and Taylor EQ (free) include the GuitarJack control panel, where users can select an input and set the input/recording level. GuitarJack Model 2 is also a great-sounding input/output solution for third party amp models and recording apps like Apple’s GarageBand app.

  2. Which devices work with GuitarJack Model 2?
    GuitarJack Model 2 works great with iPhone 5, iPhone 5c, iPhone 5S, iPod touch (5th gen.), iPad mini and iPad 4 using Apple's Lightning to 30-pin Adapter cable (0.2m). You may use a CableJive dockXtender cable if you would like a longer length. Sonoma's testing included GuitarJack Model 2 with GuitarTone and FourTrack recording through GuitarJack Model 2's 1/4" and 1/8" inputs separately onto one track as well as simultaneously onto two tracks. GuitarJack Model 2's sound quality continues to be "impeccable with no discernable noise." The cable version of the Lightning connection adapter is recommended because it offers a more space and flexibility between the device and GuitarJack Model 2. Contact support with questions.

    • GuitarJack Model 2 offers industrial design and metal finish improvements (was powder coated, now black nickel plated with stainless steel side panels).
    • In general, the tech specs for GuitarJack Model 2 are better than the tech specs for GuitarJack Model 1. The minor exception is the headphone output, which is a bit lower output now, but continues to be an improvement over the iPhone 4 headphone output. See changes from GuitarJack Model 1 => GuitarJack Model 2 here:
      • Line/Headphone Output:
        • Max level (16ohms): 1.23Vrms (95mW) => 1.00Vrms (63mW)
          For comparison, the iPhone 4 headphone output into 16 ohms is about 45mW.
        • Max level (10kohms): 1.30Vrms (+4.5dBu) => 1.00Vrms (+2.2dBu)

  7. Does GuitarJack require batteries?
    Can my iPhone, iPad or iPod touch charge while using GuitarJack?

    GuitarJack is device-powered, so it requires no batteries. While you cannot charge your iOS device while GuitarJack is plugged in, you can use your device for more than 8 hours with GuitarJack. Sonoma has demoed GuitarJack with FourTrack, StudioTrack and GuitarTone at trade shows for more than 8 hours continuously before needing to recharge (screen brightness set to less than 30% optimizes battery life).

  8. How do I get started using GuitarJack Model 2?
    Plug a 1/4 inch and/or 1/8 inch connector into GuitarJack Model 2. Plug headphones into the 1/8" stereo/line out on the GuitarJack Model 2 - for best results do not use the headphone output on the iPhone/iPad/iPod touch.

    Plug GuitarJack Model 2 in via the dock connector on the iPhone/iPad/iPod touch before launching a GuitarJack Model 2 enabled app like FourTrack, StudioTrack, GuitarTone, and Taylor EQ. The GuitarJack Model 2 control panel is located under Song Tools Model 2 in those apps. The GuitarJack Model 2 control panel is where you can select a mode and set the input level before recording. The default input configuration, when GuitarJack Model 2 is first connected, uses the Instrument (1/4") input in Lo-Z mode for the left channel and the Mic/Line (1/8") input in Normal mode for the right channel.  This allows GuitarJack Model 2 to work well out of the box with most third party audio apps like other recording and amp apps, even if they don't have a GuitarJack Model 2 Control Panel. To change modes or set levels for GuitarJack Model 2 use with third party apps, configure the settings using an app with the GuitarJack Model 2 control panel (eg. FourTrack, StudioTrack, Taylor EQ or GuitarTone, then quit to launch the third party app (see which apps you can use with GuitarJack Model 2). GuitarJack Model 2 will retain the current settings and levels even when the iOS device goes to sleep or the GuitarJack Model 2 is disconnected.
    See demo video: Using the GuitarJack Model 2 SongTool inside StudioTrack.

    See the guide above and these frequently asked questions for more information. Contact GuitarJack support with any questions.

  9. Will GuitarJack Model 2 iOS interface allow me to adjust the input level?
    GuitarJack Model 2 allows you to adjust the analog input level for 60 dB of analog input gain (72 dB with the 12 dB pad) controlled with the GuitarJack control panel, located under Song Tools in FourTrack, GuitarTone, StudioTrack, and Taylor EQ. Observe the metering in the GuitarJack Model 2 Song Tool to prevent clipping and set gain level appropriately.

  10. Does GuitarJack Model 2 do input monitoring?
    Input monitoring is on by default in FourTrack. The input signal can be heard through the 1/8" headphone output on GuitarJack Model 2 via the GuitarJack Model 2 Song Tool so you can adjust your input settings, but will be silent when you exit the GuitarJack Model 2 Song Tool. Arming a new track will begin monitoring in the headphones.

  11. What is the latency in GuitarJack Model 2 Model 2, and latency through GuitarJack Model 2 and whatever app is being used (while in-app monitoring is on)?
    GuitarJack Model 2's latency is 40 samples, which is less than 1 millisecond. The OS itself adds 176 samples. FourTrack's input and output buffers are both 512 samples. This number could be reduced, but we want FourTrack to run on as many devices as possible. The buffersize chosen for FourTrack is a compromise between latency and processing efficiency for all the tasks that FourTrack needs to accomplish on iPhone 3GS, iPhone 4 and iPhone 4S. We are working to reduce it, and may offer a lower latency option on more powerful devices like the iPhone 4S. The overall latency of running GuitarJack Model 2 and FourTrack with input monitoring on is about 1240 samples, which is about 28 milliseconds.

    Sonoma measured the latency in/out through Garageband for iPad of 3 mobile interfaces. The tests were done in ProTools (with an Mbox 2 interface) by recording the click track, in order to see if there was any latency (there was none). Once we had this audio, we then played the audio through each interface into Garageband for iPad (on the new iPad), out through the headphone jack (or in GuitarJack's case, the headphone out on GuitarJack Model 2) back into ProTools and compared them with the audio recorded in ProTools. The number of samples off the audio is the latency. Here is the information:

    Latency in/out through Garageband for iPad:
    GuitarJack Model 2 892 samples = 20.2 m/s
    Apogee Jam 962 samples = 21.8 m/s
    Line 6 MobileIn 1022 Samples = 23.1 m/s

    Apogee measured latency from MiC through GarageBand iPad to iPad headphone output to be 23ms.

    Also, Sonoma has managed to lower the latency in GuitarTone 2 substantially on newer devices. We are submitting this update to Apple soon.

  12. How do I switch between recording pairs of tracks and one track at a time?
    Use the GuitarJack Model 2 Control Panel Song Tool in FourTrack or StudioTrack to select either 1/4 inch (mono), 1/8 inch (mono, dual-mono or stereo), or both inputs (mic/line input on left channel and instrument on right channel).

  13. Why am I not getting signal on both channels?
    If you're trying to get signal on two channels, here are some things to check:

    • Make sure you are using a stereo microphone with an appropriate connector cable, like the ones listed here.
    • What kind of cable are you using to connect to the GuitarJack Model 2? Some 1/8" adapters split the left and right to separate connectors, some just duplicate the left signal to both outputs. Make sure yours actually splits the left and right to separate RCA, XLR or 1/4" connectors.
    • Test your cable and/or adapter with another device to make sure it's working.
    • If you are using GuitarTone to setup GuitarJack Model 2, then go to the Mixer and make sure Monitor Level 2 is turned up. The GuitarTone app doesn't have pan controls at the moment, so both inputs will be in the center. We want to add pan ASAP.
    • If you are using FourTrack, make sure the pan controls are set correctly on the FourTrack mixer. If channel 1 and 2 (or 3 and 4) are both panned left, then it will sound like both inputs are on the left side.


  14. Why can't I hear the microphone in "Both" mode?
    If using a mono microphone, it needs to be connected to the right channel of the stereo mini-connector. Most mono adapters only connect to the left pin, so use one of these 4 stereo splitter cables and connect the microphone to the right channel. Also make sure to select the "Both" tab in the GuitarJack Model 2 control panel. You can only record on 2 tracks simultaneously in apps that support that behavior, like FourTrack and StudioTrack.

  15. Can I connect the output of GuitarJack Model 2 to the input of a guitar amp?
    Use a 1/8" stereo to dual male 1/4" cable. Plug one of the 1/4" jacks into the amp. Leave the other 1/4" plug hanging (unless you have a stereo amp). Since the output of GuitarJack Model 2 is stereo, a mono cable will get the same signal on the tip and ground, so a mono cable won't work well.

  16. Does GuitarJack Model 2 work with Garageband on iPhone, iPad and iPod touch?
    Yes, GuitarJack Model 2 works with GarageBand on iPhone, iPad and iPod touch. GuitarJack Model 2 works better than other input accessories because it has the best sound quality. GuitarJack Model 2 works great with FourTrack on the iPhone and StudioTrack for iPad because FourTrack and StudioTrack can record an 1/8" input in stereo onto two seperate tracks, and they can record an 1/8" input and 1/4" input simultaneously onto two separate tracks (Garageband does not include these features).
    • Does GuitarJack Model 2 allow recording of guitar in GarageBand on one track? Yes
    • Does Garageband allow stereo recording on two tracks like FourTrack does? No, GarageBand does not allow for stereo inputs to be on two separate tracks. However, GuitarJack Model 2 does enable stereo recording onto one stereo track in GarageBand.
    • Does GuitarJack Model 2 allow for simultaneous voice and instrument recording in GarageBand? While GuitarJack Model 2 lets each channel of input come from different sources, GarageBand does not allow for separate recording of inputs onto separate tracks like FourTrack and StudioTrack do. FourTrack or StudioTrack, paired with GuitarJack Model 2, do allow simultaneous voice and instrument recording onto separate tracks.
    • Does GuitarJack Model 2 work with the amp models in GarageBand? Yes, and selectable input impedance, configurable via the GuitarJack Model 2 control panel, ensures both passive and active pickups will sound their best with any amp models. Also try Sonoma's GuitarTone amps and effects app and song tool included in FourTrack and StudioTrack.
    • In a nutshell, GuitarJack Model 2 is compatible with GarageBand for both instrument and microphone recording, with mono or stereo inputs to either one mono track or one stereo track. While GarageBand does not currently support recording two mono sources to two separate mono tracks, the FourTrack and StudioTrack recording apps can record separate mono sources to their own tracks.


  17. Does GuitarJack Model 2's dock connector come loose too easily?
    GuitarJack Model 2 was designed to be resting on a flat surface, since you cannot hold it while also playing a guitar. An average guitar cable weighs more than GuitarJack Model 2 and your iPhone together, so it is important to not allow your cable to yank the phone around. We've used a competitor's cable-based accessory, and the first time we plugged a guitar cable into it, the accessory and iPhone were pulled right off the table. As a safety measure, we wanted GuitarJack Model 2 to be able to come loose if cables are yanked. This helps keep iPhones/iPads/iPod touches from flying around the room. Guitar cables often get pulled out of even the most rugged amps and guitars due to moving around while playing, so many guitar players loop their cables through their guitar strap and through the handle on top of the amp to prevent them from unplugging, or worse, bending or breaking the jack on the guitar or amp. Similar measures to restrict guitar cable movement using other immovable objects should be taken when using GuitarJack Model 2.

    If you prefer a cable connection, dock extender cables can be had for very little money (dock extender recommendations below). Sonoma considered using a cable, but decided that with the availability of extenders, having a direct connection provides the most flexibility.

  18. Will dock extender cables add distance between GuitarJack Model 2 and the iPhone/iPad/iPod touch?
    While many users enjoy using GuitarJack Model 2 with no cable, some users like the distance that a cable solution provides, but prefer to use GuitarJack Model 2 over competing cable solutions because GuitarJack Model 2 is the best sounding solution with the most features. For those users, we recommend the CableJive DockXtender 30-pin Extender Cable (2 foot) and CableJive dockXtender 30-pin Extender Cable (6 foot) because we have tested them, and they work great with GuitarJack Model 2. The CableJive DockExtender 30-pin Extender Cable (2-foot) and (6-foot) are available for purchase in our store. We have noticed no problems with increased impedance or reduced sound quality when using these cables. Other cables may cause issues with impedance, but we have not tried them.

    Apple's Lightning to 30-pin Adapter Cable works great to add a little distance between GuitarJack Model 2 and your Lightning iOS device. You may also add a CableJive dockXtender cable to this set up if you would like even more length.

  19. How does GuitarJack Model 2 compare with other iOS audio interfaces?
    What makes GuitarJack Model 2 the best audio interface for iPhone, iPad and iPod touch?

    With GuitarJack Model 2, you get proven high quality sound, designed by Joe Bryan, known for his work for Universal Audio, including the UA 2192. Reviewers consistently say that GuitarJack Model 2 sounds superior to other iOS audio interfaces. Sonoma recommends that you check out sound quality and feature comparisons of iOS audio interfaces by reviewers below, the GuitarJack Model 2 reviews page, reader comments in news articles, online store product reviews, and more. You will see several reviews that find GuitarJack Model 2 sounds the best. GuitarJack Model 2 helps musicians achieve the highest quality sound possible on iOS with superior components, controllable input level control with 60 dB of gain plus 12 dB pad for 72 dB of adjustment, configurable Lo-Z and Hi-Z modes, and more.

    How GuitarJack Model 2 is better than headphone input connecting accessories:
    When compared with audio input adapters that connect via the headphone input, GuitarJack Model 2 has the least amount of crosstalk. The headphone input inherently has a lot of crosstalk (noticeable with recording and input-monitoring), and the only way to have access to communicate with software (necessary for stereo recording and more) is via the dock connector. GuitarJack Model 2 offers the quieter and software-controllable dock connector route.

    How GuitarJack Model 2 is better than other Dock connecting accessories:
    GuitarJack Model 2 offers several features that most other dock connecting accessories do not offer: stereo recording and simultaneous voice and instrument recording with recording apps like FourTrack and StudioTrack (many other interfaces only record in mono); a 1/4 inch instrument input with software configurable pad, Lo-Z and Hi-Z modes and 60 dB of continuous level control; a 1/8 inch stereo mic/line input with configurable pad and 60 dB of continuous level control - settings are remembered in GuitarJack Model 2 so it can be used with virtually any third party audio app; and an 1/8 inch stereo output with increased drive for headphones (many interfaces have no out); and 24-bit AD/DA converters (many others only have AD with no out). It's made in the USA out of high quality components, and it is made of metal instead of plastic. Simplicity in design, highest quality audio for the price, more compact (fits in your pocket), more portable (designed to be mobile), more durable (people say you can run it over with a car, though we don't recommend it!).

  22. How does GuitarJack Model 2 compare with AmpKit LiNK?
    Big-Geek.com comparison review of GuitarJack Model 2 and Ampkit LINK: "There's a dramatic difference in sound quality between the GuitarJack Model 2 and AmpKit LiNK iPhone interfaces...What should jump out at you is that, while the AmpKit sample may sound a little louder, it comes at the price of including a lot of background hiss and a relatively harsh sounding guitar tone. Contrast that with the GuitarJack Model 2 sample and you’ll hear a much deeper, more resonant guitar tone that isn’t competing at all with the background hiss present in the AmpKit sample...Listen to the samples though and I'm sure you'll hear there is a clear difference"

    ipadcreative.com compares GuitarJack Model 2 and AmpKit Link "In our opinion, audio recorded via the GuitarJack 2 sounds better, cleaner, more dynamic and more reliably useable than that of any other audio interface we have used for iOS devices. If you are serious about your sound, if you want the best possible start and quality of audio recording that you can reasonably expect on your iPad, iPhone or iPod Touch, then we think you should sell something else and/or scrape together the pennies to buy yourself the GuitarJack 2." Audio Examples: GuitarJack Model 2 sounds better than AmpkKit Link and iRig Mic. "GuitarJack Model 2 is far superior and offers the cleanest signal we have heard so far, even without a Noise Gate." (Sonoma says, "Noise Gate Coming Soon")

  26. Why is GuitarJack Model 2 more expensive than some other options?
    The engineering, chips, circuitry, 3 jacks, 30 pin connector, machined aluminum housing and other high quality materials involved in producing it makes GuitarJack Model 2 cost more to produce than adapters that plug into the headset jack as well as other less expensive dock connecting accessories. With GuitarJack Model 2, you get proven high quality sound, designed by Joe Bryan, famous for his work for Universal Audio, including the UA 2192. GuitarJack Model 2 is made in America, which causes it to be more expensive to produce than many other options. If you are looking for the best sounding solution that works best for recording, GuitarJack Model 2 is the premium choice.

  27. Which apps can I use with GuitarJack Model 2?
    GuitarJack Model 2 works best with FourTrack for iPhone ($4.99), StudioTrack for iPad ($9.99), GuitarTone ($2.99), and Taylor EQ (free) because they include the GuitarJack Model 2 control panel. StudioTrack and FourTrack have unique features, like simultaneous instrument recording onto two tracks and stereo recording onto two tracks. Additional amps and effects ($19.99 value) are enabled for free in GuitarTone, StudioTrack and FourTrack while GuitarJack Model 2 is connected.

    GuitarJack Model 2 is compatible with many third party recording apps, guitar tuners, and audio effects apps, like Apple's GarageBand, even if they do not have a GuitarJack Model 2 control panel. To change modes or set levels of GuitarJack Model 2 for use with third party apps, configure the settings using an app with the GuitarJack Model 2 control panel (like GuitarTone), then quit to launch the third party app. GuitarJack Model 2 will retain the current settings and levels even when the iOS device goes to sleep or GuitarJack Model 2 is disconnected.

    GuitarJack Model 2 users have reported success using GuitarJack Model 2 with the following third party apps. We're sure GuitarJack Model 2 works with even more audio apps! Sonoma Wire Works is keeping track of GuitarJack Model 2 compatible third party apps in the GuitarJack Model 2 Forums.

  28. Is there a free app with the GuitarJack Model 2 control panel?
    The GuitarTone amps, effects and tuner app (only $2.99) and Taylor EQ (free) that Sonoma developed in conjunction with Taylor Guitars include the GuitarJack Model 2 control panel. Many of Taylor EQ's features are built-in to FourTrack and StudioTrack as a Song Tool. GuitarTone's amps, cabinets, and effects are unlocked in FourTrack and StudioTrack when your device is connected to GuitarJack Model 2.

  29. What is the Taylor EQ app?
    The Taylor EQ iOS app is an input EQ for enhancing the sound of a Taylor guitar when played through GuitarJack Model 2 on an iOS device. Players can select from a range of EQ presets that complement Taylor's signature guitar body shapes, including the Grand Auditorium, Grand Symphony, Grand Concert, Dreadnought, T5, or the new GS Mini. Each EQ preset was custom designed by Taylor Guitars' engineers to optimize the tone of each body shape for use with the GuitarJack Model 2. Players can also create a custom tone for any guitar by using the six-band parametric equalizer in Advanced EQ mode, and play along to their favorite songs by launching Taylor EQ while the iPod app is playing.

    While the Taylor EQ app will work with most guitar adapters and any acoustic guitar, it is optimized for use with the GuitarJack Model 2 and Taylor guitars equipped with the company's Expression System® for the highest quality sound. Taylor EQ includes the GuitarJack Model 2 control panel, which allows users to configure the GuitarJack Model 2 settings and levels. Many Taylor EQ features are built-in to FourTrack and StudioTrack to enhance recordings of Taylor guitars or any other acoustic guitar.

  30. What are Taylor EQ app's features?

    The Taylor EQ Features:

    • Six Taylor Guitar EQ Presets: Select from a range of EQ presets that complement Taylor's signature guitar body shapes, including the Grand Auditorium, Grand Symphony, Grand Concert, Dreadnought, T5, or the GS Mini.
    • Advanced Mode: Use the 6 band Parametric EQ with frequency, gain and pinch-for-Q gesture control to create a custom tone for your Taylor Guitar or any guitar. Then save the settings for later use. Toggle between basic and advanced to hear the difference.
    • iPod Playthrough: Play along with your iPod songs on your iPhone or iPod touch while in the Taylor EQ app.
    • Compressor/Limiter: A factory configured compressor-limiter sweetens the sound and keeps the output from clipping, or turn it off to hear the unprocessed output.
    • Monitor Level: Balance the level when playing along with iPod songs. Turn it up to push the compressor harder.
    • GuitarJack Model 2 Control Panel: GuitarJack Model 2 connects instruments, stereo line inputs and mics to the iPod Touch (3rd generation) via 1/4 inch instrument and 1/8 inch stereo mic/line inputs. GuitarJack Model 2 features a 1/4 inch instrument with configurable pad, Lo-Z and Hi-Z modes, a 1/8 inch stereo mic/line input that includes pad, normal and boost modes, and a 1/8 inch stereo output with increased drive for headphones. Each input has 60dB of continuous gain/level control. You can configure GuitarJack Model 2's levels in Taylor EQ for the best possible sound, and what you'll hear through the improved headphone jack sounds better than through the iOS device headphone jack. Levels set using Taylor EQ's GuitarJack Model 2 Control Panel settings will remain set when you switch to compatible audio apps, even if they do not include the GuitarJack Model 2 Control Panel.


  31. What are the differences between the Taylor EQ app and the Taylor EQ Song Tool in FourTrack and StudioTrack?
    The Taylor EQ Song Tool built-in to FourTrack and StudioTrack includes all the same features as the Taylor EQ app except there is no iPod playthrough and no preset saving and loading. Taylor EQ preset saving and loading will be coming to FourTrack and StudioTrack. iPod playthrough is not possible in FourTrack and StudioTrack.

  32. What are the differences between the GuitarTone app and the GuitarTone Tool in FourTrack and StudioTrack?
    The GuitarTone Song Tool built-in to FourTrack and StudioTrack includes many of the same features as the GuitarTone stand-alone app with some exceptions:
    • Purchases of additional AmpPacks and PedalPacks can only be purchased in the GuitarTone stand-alone app. Packs are instantly activated in GuitarTone , FourTrack and StudioTrack on any device that uses the same iTunes account.*
    • GuitarTone stand-alone app allows iPod playthrough, but FourTrack and StudioTrack do not.
    • GuitarTone 2.1 stand-alone app tones are updated and improved from the tones that are included in FourTrack's and StudioTrack's GuitarTone 1.1 song tools.
    • GuitarTone stand-alone app has been updated to version 2.1 to include Audiobus, making it possible for multiple Audiobus enabled music apps to work together. Audiobus Input and Filter support allows you to record your guitar with the incredible sounds of GuitarTone in Audiobus enabled apps, like GarageBand, or filter the output of another app, like NLogSynth, before recording it. FourTrack and StudioTrack do not yet include Audiobus.
    • A 24-bit firmware update for GuitarJack Model 2, the best sounding guitar interface for iPhone, iPad and iPod touch, his now included in the GuitarTone 2.1 stand-alone app update. Also, with this firmware update, input level controls in GarageBand and Multitrack DAW now work with GuitarJack Model 2. FourTrack and StudioTrack do not include this firmware update.


  33. Can third party amp modeling apps connect directly to the FourTrack app?
    As of iOS 4.1, and prior to Audiobus, it was not possible to have the audio from one app running into the input of another, so one app could not mix into another app. The multi-tasking behavior on the phone was quite limited in terms of audio routing between apps. Without AudioBus, audio can not be blended from one app into the main output along with other apps, like running Pandora in the background, or listening to the iPod app while using the Taylor EQ app. Two apps using inputs could not be run at the same time. Only the foreground app has access to the audio input signal, so even if you could put AmpKit into the background, it would not have access to the audio input signal.

  34. Does Sonoma make any amp or pedal modeling software for FourTrack and GuitarJack Model 2?
    Yes, Sonoma makes the GuitarTone app, a standalone app and a Song Tool in FourTrack and StudioTrack. GuitarTone includes Audiobus support, but FourTrack and StudioTrack do not yet support Audiobus. FourTrack and StudioTrack include GuitarTone amps and effects so it is not necessary for using these amps and effects.

  35. What is the GuitarTone app and what are its features?
    GuitarTone is an amp and effects App and Song Tool in FourTrack and StudioTrack. Please see the GuitarTone page for more information.

  36. Which microphones and audio cables are recommended for use with GuitarJack Model 2?
    GuitarJack Model 2 will work with any un-powered dynamic microphone, eg. Shure SM-57, SM-58, EV RE-20, Sennheiser MD-421, and more. An XLR to 1/4" cable or adapter will be required. A low-Z to hi-Z impedance adapter is NOT required. GuitarJack Model 2 does NOT provide phantom power, but it can be used with mono or stereo battery powered condenser microphones. Sonoma Wire Works has tested GuitarJack Model 2 with the following battery powered condenser mics:
    • Rode NT4 ($899 MSRP) - stereo XY condenser microphone with two externally biased 1/2 capsules with gold sputtered diaphragms. Phantom power or 9V battery operation. Doug Wright, Sonoma Wire Works' CEO, uses the Rode NT4.
    • AKG C1000S ($399 MSRP) - cardioid condenser microphone, great for mobile recording or live sound. Phantom or battery power.
    • Sony ECM719 ($89.99 MSRP) - one point stereo microphone.
    • Sony ECM-MS907 ($99.99 MSRP) - one-point MS stereo electret condensor mic with adjustable pickup angle.
    • More microphones listed in the GuitarJack Forum Microphone thread.

    GuitarJack Model 2's 1/4" connector is unbalanced (TS) only. Mono microphones can be connected to the 1/4" connector, but the 1/4" connector will not have the boost mode that the 1/8" connector features. Some XLR-1/4" cables have impedance conversion built in or connect the wrong pins to the 1/4" cable.

    GuitarJack Model 2's 1/8" connector is stereo unbalanced (TRS). It has >72dB of gain with boost mode enabled and the slider at max so you should be able to get plenty of signal level from your microphones. The best way to connect gear is using a Y cable for the type of connection you require so that you can connect the mic to the left or right depending on the situation, for example, we recommend the following depending on your needs:

  37. What do reviewers think?
    • Tape Op Magazine - "Physically, it's a thing of beauty - and sturdy too. It feels like a nice solid block of aluminum and is about half the size of an iPhone. Yes, you can do simultaneous recording of both guitar and a mic'ed signal - the GuitarJack Model 2 is likely the smallest iOS device that allows this. I tried the GuitarJack 2 out on both my iPad and iPod Touch, using a variety of apps such as FourTrack, GarageBand, and Moog's Filtatron (a fave). Worked like a charm and sounded fantastic with both electric guitar and line-level signals. Very quiet with plenty of headroom, and not a hint of RF hum."
    • Today's iPhone -"GuitarJack Model 2 is beautiful. Its chunky, industrial, metallic feel mimics that of a heavy guitar pedal and should give most active performers some reassurance that it can’t be easily broken. The smoked chrome finish is perfect. All in all, it looks flipping fantagmagastic... This accessory is awesome, and is a must for anyone who wants to marry their guitar-god side with their tech-nerd persona."
    • Premier Guitar - The industrial design of GuitarJack suggests a tiny Steinway grand piano crossed with a silver Ferrari. The laser-etched SWW logo on the glossy steel housing adds to the impression of quality — GuitarJack Model 2, in other words, comes across as a proper piece of studio gear, not a mere accessory...higher quality data transfer, less crosstalk, and better fidelity...The better news is that it sounds as good as it looks. That’s because it boasts a proper 24-bit AD/DA converter...yes, you can record using both the guitar and microphone inputs simultaneously into FourTrack or StudioTrack. That's huge. GuitarJack Model 2 is made right here in America, too.
    • Engadget.com - "GuitarJack Model 2 is a handsome, well-built adapter for capturing ideas in instrumental and vocal form. Machined aluminum housing looks nice...also alleviated fears about damaging in a gear bag."
    • Rolling Stone - "GuitarJack Model 2 remains the top-of-the-line instrument-to-iPhone interface...impeccable sound with no discernible noise. Its solid aluminum body also has a 1/8-inch input for a microphone, so you can record on two tracks simultaneously, using the company's FourTrack or StudioTrack app."
    • The Loop - "The proof is in the sound. GuitarJack Model 2 worked beautifully...the quality of the signal was evident...a clean, clear signal for your guitar. I’ve been a fan of Sonoma Wire Works for many years. They are a company that cares about its users and they make very high-quality software and hardware products. If you’re looking for a device to play your guitar on the iPhone or iPad, I highly recommend GuitarJack Model 2."
    • SonicState - "This is the Rolls Royce...the GuitarJack Model 2... it's made of out metal...it's a completely different kettle of fish from the other ones. This has got a guitar jack in, a headphone output, and it's also got a stereo input. If you use Sonoma's own software, you can actually record multiple inputs simultaneously. it's just beautiful, it's just gorgeous. It sounds great. The converters on this are designed by someone who's famous for Universal Audio front end stuff, so it's got good heritage."
    • MusicTech Magazine - "Mobile pioneer Sonoma Wire Works has updated GuitarJack...Model 2 adds an AD/DA converter, remembers your settings even if the iOS device is asleep, and includes a spacer near the Dock connector to keep it flush with the iOS device."

  38. Is GuitarJack Model 2 24-bit?
    Yes, GuitarTone 2.1 stand-alone app includes a firmware update for GuitarJack Model 2, which includes a 24-bit AD/DA converter. Once installed, 24-bit playback and recording is possible with apps that support those features on iPhone 4 and later, iPad 1 and later, and iPod touch (4th generation) and later. Also, with this firmware update, input level controls in GarageBand and Multitrack DAW now work with GuitarJack Model 2.

    To install the GuitarJack Model 2 24-bit firmware update:
    1. Download the GuitarTone 2.1 stand-alone app from the App Store and launch the app.
    2. Connect GuitarJack Model 2 to your iOS device
    3. Follow onscreen instructions to update your GuitarJack Model 2 firmware.

What firmware version is shown? 13.4.9 is the firmware version which corresponds to the 24 bit update.


  39. Why does WiFi and 3G service disappear when I use GuitarJack Model 2 with my iPhone 4S?
    This is an iOS bug when using an iPhone 4S and GuitarJack Model 2 or other dock connecting audio accessories. GuitarJack Model 2 will work fine without WiFi or 3G. To get WiFi and 3G back, you don't have to reboot, you can just turn airplane mode on for 10 seconds and off. After disconnecting GuitarJack Model 2, WiFi and 3G will go back to normal. It is recommended to use GuitarJack Model 2 while in airplane mode. Sonoma has notified Apple about this iOS issue.

  40. Why are there audio glitches, pops, or clicks in my recordings?
    Audio glitches, pops and clicks can occur in FourTrack and other recording apps when other apps are running in the background. With the introduction of iOS 4, Apple added "multi-tasking", the ability for apps to continue running in the background. When Apple implemented this, they made it the default behavior of apps to continue running in the background even when you press the home button to "quit" the app and go back to the Springboard (aka home screen). If you double tap the home button, you can see a list of all the apps you've run since launching your phone. Some of these may be running background tasks, others aren't. Unfortunately, there is no indication of what these apps are doing, and it's at each app developer's discretion to really quit when "backgrounded". To be sure to have as much CPU and RAM available as possible for recording, we recommend users quit all other running apps. This is good advice for using other apps that you may notice this behavior with as well. We also recommend running in airplane mode to reduce radio interference, CPU usage of the phone and other radio processes, and avoid interruption of your recording by phone calls.

  41. Does Sonoma Wire Works plan to make audio interfaces or apps for Android?
    Yes, Sonoma plans to make interfaces and apps for Android. See Sonoma's Android™ Low Latency Audio Solution, Sonoma LLA Frequently Asked Questions and GuitarJack 2 USB product announcement.

    Sonoma hasn't released multitrack recording or amps and effects apps yet on Android because there is no synchronized record and playback system on shipping Android devices, which is necessary for multitrack recording and amps and effects processing. Sonoma is preparing software and hardware ready to launch as soon as Sonoma's LLA is installed on Android devices.

  48. iOS 7 Issue: How do I give permission for an app to access the built in microphone or GuitarJack Model 2?
    In iOS 7 a user is presented with a popup when launching any app that uses the microphone. They have to give permission to the app to access the microphone. If you select "no" that app (FourTrack, StudioTrack, GuitarTone) cannot get input from the device. Even though it seems to only refer to the built in microphone, it really means ALL audio input including GuitarJack Model 2.

    To fix this, the user needs to launch the Settings App and go to Privacy - Microphone and then change the switch so it shows green.
