From Fairfield Circuitry:
A state-variable filter with wide range and application. Versatile. Combining tilt and notch/boost equalization around a 2nd-order (-12dB/octave) state-variable core.
Very much a one-band parametric equalizer with gritty extras:
- Shelving filter, from low-pass to high-pass
- CV inputs for resonance (Q) and frequency (F)
- V/octave scaling synthesizer interface
- Fully variable Q goes well into tasty sweet self-oscillations
- Soft clip zener zesty mordant
- Expression pedal input controls center frequency
