Parametric EQ w/ Tilt & CV

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

USES

Flexible tone stack allowing for careful tuning of desired response
Stacking before/after other pedals for dramatic emphasis/deemphasis
With an expression pedal for wah-type debaucherie
Standalone channel strip EQ for outboard processing
Integrated with a modular synthesizer mindset, can act as a VCF and a VCO
With external CV control such as sequencers and keyboards
