Manufacturer's Description

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


  • 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
