Fairfield Circuitry 20% More Slew Limiting Distortion Pedal
Explorations around a schematic found among old papers of mysterious origin, suspiciously similar to a datasheet sq/tri oscillator. All that was needed was to connect the dots.
A slew limiter smoothes out how quickly incoming voltage can change, limiting it to a fixed v/sec. slope. Since time and frequency are intrinsically linked, this acts as a steep, somewhat distorted low pass filter.
When it resonates, these fixed slopes become triangle wave oscillations, giving 20% More its unique sound. Input signals can overwhelm this oscillation, making for pseudo-wavefolding and synthetic distortion artifacts.
