Used MXR M103 Octave Blue Box Effect Pedal

Unleash thick, vintage-style fuzz and subterranean octave tones with this used MXR M103 Octave Blue Box in good condition. It blends a gritty fuzz with a two-octaves-down signal for massive, synth-like leads and snarling riffs that cut through any mix. Simple controls for Output and Blend let you dial in anything from subtle octave grit to full-on low-end chaos. Standard 1/4" in/out; compact MXR stompbox design.
