The MGT-4 pedalboard (included with Mustang GT200) is an excellent optional accessory for Mustang GT100 and GT40. It's a four-button, pedal-friendly unit that allows users to select various presets and ground effects. It also provides hands-free access to the chromatic tuner, with colored LEDs for visual feedback. Perhaps most importantly, the MGT-4 foot pedal unlocks Mustang GT's 60-second Looper functionality, with buttons to activate "Record", "Play", "Overdub" and "Stop" functions. Acoustic 100 and 200 amplifiers come with a magnetic overlay that updates the switch labels to the correct functions. Removable 12-foot cable with 1/4" plugs included.
