Used MXR M103 Octave Blue Box Effect Pedal

Unleash massive, vintage-style low end with this used MXR M103 Octave Blue Box in great condition. This iconic analog octave fuzz pairs a gritty fuzz tone with a deep sub-octave (down two octaves) for synthy riffs, booming leads, and wild textures that cut through any mix. Simple, stage-ready controls for Output, Blend, and Fuzz make dialing in everything from subtle thickness to full-on chaos fast and fun. Rugged MXR metal housing.
