It's equipped with a large LED display that is easily seen from the floor. Plus, it also has both Calibration and Choose Note features. The AC-1 is protected by die cast housing and it even features non-skid rubber feet. Thanks to its flexible tuning options and durable craftsmanship, the AC-1 is an ideal touring stomp box tuner.
