Blended 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.

The Boss OC-2 Octave is a monophonic analog octave pedal capable of generating one and two octaves below the input signal simultaneously. Three controls (Direct, Oct 1, Oct 2) allow blending the dry guitar signal with one octave down and two octaves down in adjustable proportions. The monophonic tracking requires single-note playing for accurate octave generation. Originally released in 1982 and produced until 2002, the OC-2 became a vintage staple for bass-imitation tones, sub-bass textures, and funk playing. This unit is a vintage original from August 1990.
The Old Blood Noise Endeavors BL-13 Octave is part of the brand's BL series of variable-clock effectors, pairing octave-up and octave-down voices with a touch of reverb for a drifting, out-of-sorts, grimy ambience. Rather than a clean, precise octaver, it leans into character, producing unstable, atmospheric octave textures with a lo-fi haze, and its variable system clock lets players move between cleaner, higher-fidelity tracking and darker, degraded, drifting tones. It suits experimental, ambient, and shoegaze players who want octave effects with built-in mood and grit rather than surgical accuracy. Now discontinued, it remains a distinctive, texture-focused octave-and-reverb box for those chasing evocative, slightly broken octave ambience in their sound.
