DIY Polivoks VCF II (Full Kit) – Erica Synths

DIY Polivoks VCF II (Full Kit) – Erica Synths


Polivoks VCF is famous for its’ crazy resonance sweeps and deep, bassy sound which makes it ideal for acid basslines.

We believe, this is one of most is one of most authentic sounding famous Russian synth Polivoks VCF emulations available. The original Russian ICs K140UD12 are used in the sound circuit. We 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.


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