Used MXR M103 Octave Blue Box Effect Pedal

Add gritty, synth-like low end to your rig with this used MXR M103 Octave Blue Box in good condition. It blends your dry guitar signal with an octave-down and a two-octaves-down fuzz for massive, vintage-style textures perfect for riffs, leads, and experimental tones. Features simple Level and Blend controls, true hardwire bypass, rugged MXR housing, and runs on a 9V battery or standard 9V DC adapter.
