Used MXR M103 Octave Blue Box Effect Pedal

Used MXR M103 Octave Blue Box in great condition delivers the legendary fuzz-and-sub-octave grind heard on countless rock recordings. This compact analog pedal blends a snarling fuzz with a deep octave-down signal for thick, synthy leads and massive riffs. Simple controls let you dial in Output and the mix between fuzz and octave for everything from subtle thickness to wild, gated chaos. Rugged MXR metal housing with standard 1/4" in/out and 9V operation.
