The Morley Accu-Tuner places strobe and chromatic tuners into a stage-sturdy stomp box. The tuner remembers the last tuner mode you were in and stays there until switched. A second output lets you mute your instrument for silent tuning. The Morley Accu-Tuner is also equipped with calibration and choose-your-note features. Contains the largest LED display on a floor tuner. It has roadworthy, die-cast housing with an easy-access battery door.
