The Fender GTX-7 footswitch was developed for use with Mustang GTX amplifiers, allowing users to select various presets and effects from the floor. Looper buttons access the amp’s “Record,” “Play,” “Overdub,” “Stop” and “Undo” functions. Tap Tempo is accessible for time-based effects. The chromatic tuner is also selectable on demand. Removable cable with 1/4” plugs included.
