Sleek Design
Engadget.com - "GuitarJack Model 2 is a handsome, well-built adapter for capturing ideas in instrumental and vocal form. Machined aluminum housing looks nice...alleviated fears about damaging in a gear bag."
Tape Op Magazine - "Physically, it's a thing of beauty - and sturdy too...simultaneous recording of both guitar and a mic'ed signal...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."
Rolling Stone - "GuitarJack 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..."
Premier Guitar - "The industrial design of GuitarJack suggests a tiny Steinway grand piano crossed with a silver Ferrari...higher quality data transfer, less crosstalk, and better fidelity...it sounds as good as it looks...yes, you can record using both the guitar and microphone inputs simultaneously into FourTrack or StudioTrack. That's huge. GuitarJack is made right here in America, too.
The Loop - "The proof is in the sound. GuitarJack worked beautifully...the quality of the signal was evident...a clean, clear signal for your guitar."
SonicState - "This is the Rolls Royce...it's a completely different kettle of fish from the other ones...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."
