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 Black Arts Toneworks FNORD is an octaver-fuzz hybrid pedal blending a scrambler or octave-up fuzz circuit with a conventional fuzz and distortion voice. A blend control mixes between the two characters, spanning from zipper, velcro-style octave fuzz tones to full-throated conventional distortion, or any combination of both voices simultaneously. Suited for psychedelic, noise, and experimental rock where unconventional octave-fuzz textures are wanted alongside conventional high-gain distortion. Made by Black Arts Toneworks.

The MXR M103 Blue Box is an octave fuzz that duplicates the guitar signal two full octaves down for a huge, subterranean, synth-bass tone layered with fuzz. The Blend knob controls the balance between the fuzz and the sub-octave signal: turned fully one way it is a nasty, straightforward fuzz, turned fully the other way it becomes a fat, fuzzy synth-bass tone, and pushed toward its extreme it starts spitting, glitching, and tracking unpredictably for a raw, 8-bit-like chaos. It became a gear icon after Jimmy Page used it for the solo on Fool in the Rain, and has since been used by Jack White, Lee Ranaldo, and Thurston Moore. It suits players wanting an uncontrollable, glitchy, monstrous octave-down fuzz for experimental, psychedelic, and heavy styles rather than a clean, predictable octave effect.
