It’s a compact acoustic microphone and advanced digital preamplifier and processing unit that recreates a studio microphone set-up providing you with all of the true character and tonal nuance of your acoustic in live playing situations. Simply clip the iRig Acoustic Stage’s microphone to the sound hole, attach it to the iRig Acoustic Stage pre-amplifier processor, then connect the preamp to your amplifier or mixer. iRig Acoustic Stage also features a “Cancel Feedback” button that gets rids of annoying frequency feedback during performance.

I got a demo of this yesterday and it was pretty impressive. If you play an acoustic live, you should take a look at this.
