The iRig Acoustic works with any acoustic guitar, providing an exceptionally true acoustic tone. It features an AUX input to connect an existing guitar pickup system and blend it with the iRig Acoustic Stage signal. It features a blend and phase control along with powerful DSP that provides personalized tone calibration and four selectable variations (natural, warm, bright and lo-cut).
It additionally has a powerful feedback suppression system that immediately eliminates feedback at the touch of a button. 32-bit A/D and D/A audio conversion provides professional quality audio with USB connection to Mac/PC and iOS (with camera connection kit).
