Fairfield Circuitry 20% More Slew Limiting Distortion

The Fairfield Circuitry 20% More pedal is an innovative sonic tool that blends slew limiting, envelope following, sub-octave generation, and wave shaping to create rich, dynamic textures. Inspired by a mysterious oscillator schematic, this unique circuit delivers everything from distorted low-pass filtering to self-oscillating feedback and percussive, west coast-style gating.

At its core, a slew limiter smooths voltage changes, acting as a resonant, somewhat distorted low-pass filter. When pushed into self-oscillation, it produces triangle waveforms that interact with your input signal, generating pseudo-wavefolding and synthetic distortion artifacts. A low-pass gate (LPG) adds warmth and resonance, while an internal envelope follower dynamically shapes feedback and filtering based on your playing intensity.

The sub-octave circuit delivers thick, harmonically rich tones by routing the squared signal through clock dividers. Additionally, a full-wave rectifier provides a switchable octave-up effect, adding aggressive upper harmonics when driven hard.

Designed for deep sonic experimentation, the Fairfield Circuitry 20% More invites you to explore new harmonic landscapes with intuitive interactions and responsive controls.
