Description
The Fairfield Circuitry Long Life is a state-variable parametric EQ pedal built around a 2nd-order (-12dB/octave) filter core. It combines tilt and notch/boost equalization into a single, wide-ranging one-band parametric that covers a lot of ground — from subtle tone shaping to more aggressive filtering and self-oscillation.
The Q control is fully variable and goes into self-oscillation, and CV inputs for both resonance and frequency make it compatible with modular and semi-modular setups. V/octave scaling means it can function as a voltage-controlled filter (VCF) or even a voltage-controlled oscillator (VCO) in a synthesizer context. An expression pedal input controls the center frequency, making wah-style sweeps straightforward.
Features
- 2nd-order state-variable filter core (-12dB/octave)
- Shelving filter, continuously variable from low-pass to high-pass
- Fully variable Q with self-oscillation
- CV inputs for resonance (Q) and frequency (F)
- V/octave scaling synthesizer interface
- Expression pedal input for center frequency control
- Soft clip zener saturation
Applications
- One-band parametric EQ for precise tone shaping
- Stacking before or after other pedals for emphasis or de-emphasis
- Wah-style filter sweeps with an expression pedal
- Standalone channel strip EQ for outboard processing
- VCF or VCO in a modular synthesizer setup
- CV-controlled filtering with sequencers or keyboards
Made in Canada.
