Want to connect mics, instruments, or other audio hardware to your favorite i-devices? Check out the Sonoma Wireworks GuitarJack Model 2 ($199, sonomawireworks.com). This upgraded iOS interface offers stereo recording and simultaneous voice and instrument recording with apps like FourTrack and StudioTrack; inputs include a 1/4" instrument in with Lo-Z and Hi-Z modes, and an 1/8" stereo mic/line input. (Both inputs feature a configurable pad and 60dB of continuous level control.) The unit also has an 1/8" stereo out, and tons of new features that give it a huge edge over Model 1 (which is now discounted to $49).
