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).
