Peavey has announced AmpKit, a new guitar interface/software for the Apple iPhone, iPad, or iPod Touch. There are two parts to AmpKit, the AmpKit Link audio interface, which allows a guitar, bass, or line-level signal to feed into an iPhone, and that also has an output that can feed headphones, studio monitors, or a PA. New CrossTalk Eliminator technology eliminates the feedback problems experienced with many other iPhone interfaces.
The AmpKit software is available free through the iTunes App store, and includes a faithful model of the Peavey ValveKing amplifier, three pedals (a dozen or more pedals can run simultaneously), two speaker cabinets, and two mics. Additional amps, cabinets, pedals, and microphones can be purchased through the iTunes App store.
AmpKit also allows you to record both dry and processed guitar signals as you play, can play back backing tracks or songs as you play, and includes a tuner and metronome.
