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. Shown only within a gear class, and only where there's enough evidence to be meaningful.44% — somewhat different

The EarthQuaker Devices Fuzz Master General is an octave fuzz inspired by the classic Univox Super-Fuzz circuit, featuring a three-position diode selector switching between no clipping, germanium clipping, and silicon clipping modes. Controls include Fuzz, Volume, Tone, and a Shift knob for shaping the midrange peak and resonance. It produces a thick, harmonically complex octave-up fuzz with a broad tonal palette spanning from warm and smooth to nasal and brash. Used in psychedelic rock, heavy blues, and experimental contexts by players seeking vintage octave fuzz coloration with modern flexibility.
The Tone City Mad Stone is a budget distortion pedal built around germanium diode clipping. Germanium diodes clip at a lower threshold than silicon, so the voicing is softer, warmer and more compressed than a typical silicon distortion, with a rounded top end and a smooth, vintage-flavoured breakup rather than a sharp, cutting edge. It sits in a compact mini enclosure at an accessible price and is aimed at players wanting classic, warm distortion character without a boutique outlay.
