iRig STOMP is the an intuitive and easy-to-use stompbox guitar interface for the iPhone, iPod touch and iPad. Guitar and bass players can now integrate their favorite iOS signal processing apps into their existing live pedalboard setup for enhanced tone shaping and effects processing using an iPhone/iPod touch or iPad. iRig STOMP is based on the wildly popular AmpliTube iRig interface and is compatible with any iOS guitar / amp / instrument app. With its compact, standard stompbox shape, iRig STOMP is packed with many smart features. Built with ultra-tough, military-grade aluminum the iRig is ready for an indestructible performance. The standard size and shape make it easy to integrate into your existing pedalboard, with standard ¼” guitar input and a mono/stereo L&R out jack to send the signal through to more pedals or direct out to your amplifier. A large gain knob on the top of the pedal allows you to adjust the input signal gain structure to provide you with the maximum amount of headroom needed for your apps. The iRig Stomp is an active circuit powered either by a 9v battery or by your pedalboard power system, providing a high-quality signal with lots of headroom.
