Compact, lightweight stompbox pedal guitar interface for iPhone, iPod touch and iPad that allows guitar and bass players to integrate their favourite iOS signal processing apps into their existing live pedalboard setup for enhanced tone shaping and effects processing. It 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, interface is packed with many smart features found here for the first time in an iOS audio accessory. It can be used in line with other effects pedals, or directly connected to amplifiers or PA systems using regular 1/4" guitar cables, with no need for adapters. It allows precise adjustment of the signal for perfect guitar and bass levels with its large input gain knob. Its 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 – like a traditional stompbox – for seamless integration into any existing rig. Interface also features a 3.5mm/1/8" jack for silent practicing with headphones and comes with the #1 guitar/bass tone shaping app, award winning AmpliTube FREE for iOS (downloadable for free from the App Store). Device is powered by 9V battery. 2m long 1/8” mini jack cable is also included. Dimensions: 70 x 114 x 53 mm. Weight: 270 g.
