Premier Guitar's Review


Compatible Apps

GuitarJack is the perfect companion for GuitarTone (free), Taylor EQ (free), FourTrack and StudioTrack. Enables $19.98 worth of GuitarTone amps and effects. Works with most 3rd party audio apps like GarageB


Sleek Design - "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 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."

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, 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 is made right here in America, too.
