Used MXR M103 Octave Blue Box Effect Pedal

Add deep, synthy low end with this Used MXR M103 Octave Blue Box in Good condition. Classic analog octave fuzz drops your signal one and two octaves down for thick, glitchy riffs and huge bass-like textures. Simple three-knob control layout (Output, Blend, and Fuzz) makes dialing in everything from subtle octave grit to full-on vintage chaos fast. Rugged MXR metal housing with standard 1/4" in/out and 9V DC operation.
