Sonoma Wire Works, maker of the FourTrack recording app for iOS, has announced the GuitarJack audio device. GuitarJack connects a wide range of instruments, microphones, and other audio hardware to iPod touch (2nd and 3rd generation), iPhone 3GS* and iPhone 3G* via 1/4 inch instrument and 1/8 inch stereo mic/line inputs.

Addressing the most frequent request from musicians who use FourTrack, GuitarJack makes both level control and input monitoring possible when using a GuitarJack enhanced app.

Sonoma Wire Works is also developing the TaylorEQ app for the GuitarJack. The free TaylorEQ app will allow Taylor Guitar players to hear and adjust the tone of their guitars playing through the GuitarJack using EQ settings custom designed by Taylor Guitars.

GuitarJack will be priced at $199 MSRP. GuitarJack and TaylorEQ are scheduled to ship in Q3 2010. Pricing and availability subject to change.
