The GTX-7 Footswitch is custom-designed to work with Fender’s groundbreaking line of Mustang GTX modeling amplifiers — and it’s available from Sweetwater. The 7-switch interface has five assignable FX controls, bank switching, and mode selector. Looper mode gives you access to the amp’s Record, Play, Overdub, and Undo functions. The GTX-7 Footswitch also includes tap tempo and an on-demand chromatic tuner, and its rugged metal housing is built to withstand vigorous performances.
