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.50% — moderately similar

The MXR SF01 Slash Fuzz is a signature fuzz pedal created in collaboration with Slash, the Guns N' Roses and Velvet Revolver guitarist, designed to recreate the Dallas Arbiter Fuzz Face-style fuzz character that Slash uses for specific lead and rhythm moments. The silicon Fuzz Face-inspired circuit delivers the bright, cutting, consistently aggressive silicon fuzz character associated with classic rock lead playing, built to Slash's specific tonal requirements.
The SolidGoldFX If 6 Was 9 BC183 MKII is a silicon Fuzz Face-style fuzz built around two BC183 transistors, widely regarded as the middle ground between the mushy compression of germanium and the brash, sawmill harshness of typical silicon. The voice is smooth and refined, holding together on chords rather than falling apart, with generous sustain on single notes. Five controls -- Volume, Bias, Fuzz, Volts and Saturate -- give unusual command over the circuit: Volts sets the supply voltage so the tone no longer depends on a dying battery, and Bias combined with it reaches any shade from gated, sputtering splat through to smooth and dynamic. Saturate trims the input for better cleanup and impedance matching. A Body toggle selects three voicings: Fat, Treble Boost and Classic. It cleans up beautifully as the guitar volume is rolled back.
