The DigiTech iStomp is an entirely new concept in pedals. It works just like a traditional stompbox with one huge exception. It can be completely reconfigured by loading it with any of the 47 e-pedals available in the Stomp Shop app. Unlike devices that require you to stay tethered to your iOS device, the iStomp does all of its processing internally. This means professional-quality, high-definition signal processing with no latency and you donÕt need your iOS device while youÕre playing.
