Used MXR M103 Octave Blue Box Effect Pedal

The used MXR M103 Blue Box Octave Fuzz pedal delivers a gritty fuzz tone paired with a two-octave-down signal for a wild, synth-like sound. With just Output and Blend controls, it's simple to dial in everything from subtle textures to chaotic leads. Housed in the iconic blue chassis and in good condition, this analog stompbox runs on a 9V battery or power supply (not included) and adds unmistakable retro character to any guitar rig.
