Description

Unleash thick, synthy fuzz textures with this used MXR M103 Octave Blue Box in great condition. It combines a ripping fuzz circuit with a -2 octave subharmonic generator for massive, glitchy riffs and doom-ready leads. Simple top-mounted controls—Output, Blend, and Fuzz—make it easy to dial in anything from subtle low-end reinforcement to full-on retro mayhem. Standard 1/4" in/out and 9V operation.
