MXR® CLONE LOOPER™ PEDAL M303 Whether you're practicing at home, captivating audiences with improvisational compositions onstage, or weaving intricate sonic tapestries in the studio, the Clone Looper Pedal has you covered. Packed into a standard MXR® housing that's built like a tank, it's easier to use and delivers higher fidelity signal reproduction than any other looper of its type—hands down. This pedal can be powered by the included Dunlop ECB003 9-volt adapter, or the Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
