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 Fulltone Ultimate Octave is a fat, BC108-transistor fuzz and distortion pedal paying homage to the classic Octavia circuit, with a separate footswitch that kicks in a searing, aggressive octave-up on command rather than functioning as a clean, precise pitch-shifter. An active tone control and a Fat/Bright switch reshape both the fuzz and octave character, from a thicker, mid-forward voice to a more open, scooped-mid brightness with defined highs. Tracking holds up well across the neck, with the clearest octave definition from the neck pickup. Used by Primus's Ler LaLonde and Aerosmith's Joe Perry, it suits psychedelic and classic rock players wanting an aggressive fuzz with a genuine Octavia-style octave-up option.
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.
