A British Fuzz Icon Reborn
The Custom Shop MKI Supa Fuzz is Seeker’s recreation of a super rare prototype version of the 1960s Marshall SupaFuzz, a close cousin to the MKI Tone Bender. Built in a Silver Hammered replica Olivetti enclosure with Cliff/Marshall knobs, this pedal combines vintage-accurate construction with carefully selected components for true period-correct tone.
Known for its thick, saturated sustain and explosive character, the Supa Fuzz became an essential part of the early British rock sound, used by players such as Jeff Beck, Pete Townshend, and Steve Hackett. Seeker’s recreation captures those classic textures with gnarly sustain, textured decay, and a chunky compressed attack with beautiful note bloom.
The Filter control allows you to roll off highs and thicken the sound, while the Volume control provides plenty of output.
An internal trim pot lets you fine-tune the gain and gating, shipping set just on the edge of gating for a slightly open feel that adds character and texture.
