The iRig STOMP is a stompbox guitar interface for iPhone, iPod touch and iPad. You can integrate your favourite iOS signal processing app into your existing pedalboard setup for effects processing. It is based on the AmpliTube iRig interface and is compatible with any iOS guitar/amp/instrument app. It is compact, has a large gain knob and a standard stompbox shape. You can use it inline with other effects pedals, or directly connected to amplifiers or PA systems using regular 1/4” guitar cables, with no need for adapters. Active battery-powered output circuit improves headroom, especially when used with high-gain amplifiers in the AmpliTube app, reducing feedback and crosstalk when recording. The bypass switch allows engaging or bypassing the AmpliTube app chain of effects, and it also features a 3.5mm/1/8” jack for silent practicing with headphones. It comes with the guitar/bass tone shaping app, award winning AmpliTube, free.
