M303 Clone Looper

The MXR M303 Clone Looper is a compact looper offering high-fidelity recording with a 44.1 kHz sampling rate. Its REC/DUB footswitch handles recording, overdubbing and loop clearing, while PLAY/STOP controls playback and undo/redo. The Volume knob sets loop level and doubles as a push control for half-speed, double-speed, reverse and quiet-clear functions. External control is available through CTR and EXP jacks: a tap switch can control speed, direction, quiet clearing or Play Loop Once, while an expression pedal can control loop volume. The M303 operates in buffered bypass by default, with a selectable true bypass mode available at power-up. It requires a 9V DC supply and cannot run on a battery.
