Fairfield Circuitry 900 Fuzz

Fairfield Circuitry · pedal

The Fairfield Circuitry ~900 Fuzz is a raw, aggressive transistor fuzz pedal from Canadian boutique maker Fairfield Circuitry. Inspired by primitive vintage transistor fuzz circuits, the ~900 delivers an abrasive, spitting fuzz character with a distinctly gnarly, lo-fi texture that differs from the smooth sustain of Big Muff-style designs. Fairfield Circuitry is known for building characterful, uncompromising circuit designs, and the ~900 represents the brand embrace of maximally distorted, primitive fuzz aesthetics. It suits experimental rock, noise, and heavy garage contexts.
