Condition and what is included

Electro-Harmonix Octave Multiplexer Analog Sub-Octave Generator.

Large-box EHX analog octave pedal for deep sub-octave bass tones, synth-like textures, and vintage single-note tracking.

The Electro-Harmonix Octave Multiplexer is a classic analog sub-octave pedal built to generate a note one octave below the note you play.

This large-box NYC version gives players more tone-shaping control than a basic octave-down pedal. The High Filter shapes the upper harmonic bite of the octave voice, the Bass Filter shapes the deeper low-end content, and the Blend control balances dry signal with the generated sub-octave. The Sub switch activates the deeper Bass Filter section for thicker, bassier octave sounds.

It also includes separate Dry Out and Effect Out jacks, which is useful for wet/dry routing, sending the dry signal to one amp and the octave effect to another, or separating the original instrument from the sub-octave signal in a studio or live setup.

Condition

Good used/player-grade cosmetic condition with visible wear throughout. The enclosure shows surface patina/oxidation, scratches, scuffs, finish wear, label wear, small marks around the edges, and normal signs of previous pedalboard use.

The bottom has a large Velcro-style pad attached with visible adhesive residue/marks around it. The pedal presents as a well-used working player’s pedal rather than a collector-clean example.

Pedal only. No box, power supply, 9V battery, manual, cables, or additional accessories included.

Not Included

Original box, power supply, 9V battery, instrument cables, manual, paperwork, or additional accessories.
