Electro Harmonix Used Electro Harmonix Octave Multiplexer Effect Pedal

The Electro-Harmonix Octave Multiplexer is a dynamic analog octave effect pedal that enhances your tone with deep, rich sub-octaves. This used unit is in good condition and fully functional, delivering classic EHX warmth and growl. Featuring separate Sub and Bass filter controls, it allows you to shape the octave-down signal for smooth, rounded lows or punchy, aggressive depth.

With a rugged enclosure built to handle the demands of the stage, this pedal is perfect for guitarists and bassists looking to add thick, harmonic textures to their sound. Powered by a 9V battery or optional 9V DC adapter (not included), the Octave Multiplexer is a great addition to any pedalboard. Whether you're creating a subtle low-end boost or a massive synth-like tone, this pedal delivers versatile octave-shifting capabilities in a compact design.
