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.
