Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

The Boss OC-5 Octave is a polyphonic octave pedal offering both vintage monophonic mode and modern poly mode for chord-compatible octave generation. Controls include Direct level, plus one octave up, minus one octave down, and minus two octave down levels, with a Vintage/Poly mode switch and a Guitar/Bass input selector for frequency range optimization. In Poly mode the OC-5 tracks chords accurately. In Vintage mode it replicates the monophonic analog character of classic Boss octave pedals including the OC-2.

The Electro-Harmonix Octave Multiplexer is a vintage sub-octave synthesizer pedal from Electro-Harmonix, generating one octave below the input guitar signal to produce bass-like sub-octave tones. The large-box format is the classic vintage Octave Multiplexer enclosure, producing a monophonic sub-octave through analog frequency division. Controls include Sub Bass, Bass, and Upper Bass controls for shaping the sub-octave tone and blend with the original guitar signal.
