Used MXR M103 Octave Blue Box Effect Pedal in good condition. This classic stompbox delivers fuzz and two-octave-down effects for a thick, synth-like sound. Features include output and blend controls, true bypass switching, and rugged metal housing. Perfect for guitarists seeking vintage analog tone and gritty textures. Powered by 9V battery or standard 9V DC adapter (not included). A legendary pedal for experimental tones and fat, fuzzy leads.
