The Kit version of the VCF II contains all the components needed for the module, including ICs, knobs, power cable, etc.

Polivoks VCF is famous for its crazy resonance sweeps and deep, bassy sounds that make it ideal for acid basslines.


  • Switchable BP/LP modes
  • Inputs/outputs are protected against over-voltage
  • Protection on reversed power supply
  • Skiff friendly design


We believe that this is one of the most authentic sounding emulations of the famous Russian synth Polivoks VCF that is available out there. The original Russian ICs K140UD12 are used in the sound circuit, but we also did several updates to adapt the VCF for contemporary modular synth demands. Independently buffered inputs, extended Cutoff knob range, eliminated clicks when switching filter modes, and output stage added to eliminate signal inversion.
