  4. What sets GuitarJack 2 USB apart from other audio interfaces?
    GuitarJack 2 USB is made in the U.S.A. by Sonoma Wire Works, who has experience creating award winning mobile and desktop recording solutions. GuitarJack 2 USB is compatible with Macs, PCs, iPads and iPhone 5s. Like GuitarJack Model 2 for iPhone, iPad and iPod touch, you get proven superior quality sound, designed by Joe Bryan, famous for his work for Universal Audio, including the UA 2192. GuitarJack 2 USB is a high end recording interface that is also affordable. GuitarJack 2 USB includes 24-bit AD/DA converters (many others only have AD with no out). GuitarJack's stereo line out offers incredible increased drive, with sound quality that is better than the iOS device out (many interfaces have no out). GuitarJack 2 USB offers stereo recording (many interfaces only do mono). 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!).

  5. Is GuitarJack 2 USB Made in America?
    Yes, GuitarJack 2 USB was Made in the U.S.A. from quality components like Switchcraft Jacks from Chicago, plating from Wisconsin, packaging from California, and several other American made ingredients. GuitarJack's boards are built, and the units were assembled and tested in a factory in San Jose, California. The factory is 15 minutes away from Sonoma's office, which helps Sonoma keep a close eye on quality and testing.

    GuitarJack 2 USB is no longer being made, as it has been replaced by GuitarJack Stage and StudioJack Mini, which are made in the U.S.A. in the same factory as all GuitarJacks have been.

      GuitarJack 2 USB does not access the GuitarJack Model 2 Control Panel and does not have a Control Panel of its own. Instead, GuitarJack 2 USB input level is set using standard input level controls on mobile or desktop devices and/or select apps. GuitarJack 2 USB can record in stereo with its 1/8" input Recording can only be done using one input at a time with GuitarJack 2 USB.

  8. What are the best settings to use with ’s ASIO driver?
    The lowest recommended setting for the ASIO driver is a buffer size of 256 samples with the USB streaming Mode set to Standard. Lower buffer settings and streaming modes are possible, but are highly dependent on your system configuration and the other drivers installed. If you would like the lowest possible latency, but are experiencing audio dropouts, contact support, and we can assist you with additional troubleshooting information. Buffer settings above 1024 are not recommended, and settings above 4096 are not supported by RiffWorks. Contact support for the ASIO driver download link, and to ask any further questions.

  9. What is GuitarJack 2 USB's latency, and latency through GuitarJack 2 USB and whatever app is being used?
    GuitarJack 2 USB's hardware latency is 40 samples, which is less than 1 millisecond. The USB stack on each OS will add a variable amount of latency, usually around 150 samples. The total latency will be dictated by the buffer size in the app. Total latency under 20 milliseconds should be attainable on most platforms.

    On MacOS, the buffer size is set in each individual application settings. The smaller the buffer size setting the less lag you'll notice while playing. The trade off is that you'll use more processor power and may end up with clicks and pops while recording or during playback if you set it too small. If you set the buffer too high you'll notice lag. We've found that the best buffer size for the typical RiffWorks user is 256 samples but it depends on your app and interface. If you are having problems adjusting the buffer size in your app which can cause issues with latency, please email Email support@sonomawireworks.com, Let us know what OS you are running, what app you are using and what settings you have chosen for it so we can help you get the most out of your GuitarJack 2 USB.

  10. Can I connect the output of GuitarJack 2 USB to the input of a guitar amp?
    Yes. 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 is stereo, a mono cable will get the same signal on the tip and ground, so a mono cable won't work well.

  11. Does GuitarJack require batteries?
    Can my mobile device charge while using GuitarJack?

    GuitarJack 2 USB is device-powered, so it requires no batteries. While you cannot charge your mobile device while GuitarJack is plugged in, we know you can use your iOS device for more than 8 hours with GuitarJack 2 USB. Sonoma has demoed GuitarJack with 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).

  12. Does Sonoma make any amp or pedal modeling software for GuitarJack 2 USB?
    Yes, Sonoma makes the GuitarTone amps and effects iOs app, a standalone app and a Song Tool in StudioTrack (iPad). GuitarTone will soon feature Audiobus on iOS, so you can use GuitarTone in conjunction GarageBand and other Audiobus enabled iOS apps.

  13. Which microphones and audio cables are recommended for use with GuitarJack 2 USB?
    GuitarJack 2 USB 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 does NOT provide phantom power, but it can be used with mono or stereo battery powered condenser microphones. Sonoma Wire Works has tested GuitarJack 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 2 USB'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 2 USB'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:


  14. Is GuitarJack 2 USB 24-bit?
    Yes. GuitarJack 2 USB includes a 24-bit AD/DA Converter.

  15. Where can I find GuitarJack Images?
    GuitarJack Images

  16. Is there a warranty for GuitarJack?
    Please see the GuitarJack Warranty page.

  17. What is the return policy for GuitarJack?
    Please see the GuitarJack Return Policy page.

  18. Where can I purchase GuitarJack? Is international shipping available?
    Order GuitarJack 2 USB from Sonoma (U.S. shipping only) for $129 Intro Price ($199 MSRP). Order from select dealers worldwide approximately August 20, 2013.

  19. Where can I find more information?
    GuitarJack 2 USB Features, Detailed Technical Specifications, and more. Email support@sonomawireworks.com for any additional information.

  20. Any Known Issues?
    iOS 7: Regarding apps like FourTrack and StudioTrack - 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. 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.

    iPad: Plug the GuitarJack 2 USB into the cable first, then into the iPad. If you plug the cable into the iPad/iPhone/iPod touch first, then plug in the GuitarJack 2 USB, you will get the error message: "This device will not function because it uses too much power." If the message pops up, just unplug from the iOS device and replug and it should work fine.

    Windows 7: Using Windows 7 with GuitarJack 2 USB or other sound cards: While using the speakers button in the notification area of the taskbar to adjust your output volume, you may find it difficult to make the output volume level quiet enough without muting it entirely. Solution: To adjust the output volume, try using the volume control in the app you are playing from as well as the speakers button in the taskbar. If the app you are using doesn't include volume control, we don't recommend using GuitarJack 2 USB with that app.
