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.49% — somewhat different

The EarthQuaker Devices Fuzz Master General is an octave fuzz pedal from EQD, based on the Ace Tone FM-2 Fuzz Master circuit, which shares heritage with the Super-Fuzz design. The Fuzz Master General features a three-way toggle switch for selecting between germanium diode clipping, silicon diode clipping, and no diode clipping, alongside a variable tone-shaping Tone knob. This diode switching system produces three distinctly different fuzz characters from a single enclosure: the softer compression of germanium, the harder response of silicon, and the most open, raw character with no clipping diodes. The upper-octave harmonic content of the Super-Fuzz-inspired circuit adds a distinctive, singing octave quality to sustained notes.
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.
