Used MXR M103 Octave Blue Box Effect Pedal

The used MXR M103 Octave Blue Box delivers gritty, synth-like fuzz with a huge two-octaves-down sub tone for massive, glitchy riffs and lead lines. In excellent condition, it features simple controls for Output and Blend to dial in everything from subtle octave weight to full-on broken speaker mayhem. Built in a rugged MXR enclosure, it runs on standard 9V power or battery and uses a 1/4" input/output for easy pedalboard integration.
