They say...

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
