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 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.

The Hungry Robot The Monastery is an octave generator producing sub-octave and upper-octave voices alongside the dry signal, blended to build organ-like and synth-like textures from guitar. Independent level controls for each octave allow a thick, weighted low end from the sub-octave, a bright, glassy top from the upper octave, or a full stacked stop combining both with the dry note. Tracking is cleanest on single notes, and chords take on a fuller, more intermodulated character typical of analog octave circuits.
