Skiff format Dtech VCF sound circuit uses the original Russian ICs K140UD12 found in Polivoks VCF, and has one of most advanced control features found in VCFs around, including resonance CV, filter curve and resonance slope adjustment and unique CV assign function. It's sound ranges from deep, bassy sounds to something even more extreme than famous Polivoks resonant screams.

Dtech VCF has all buffered inputs with diode protection, diode protection on reversed power supply voltage, 1V/oct response.  Designed by my friend, genius engineer and musician Edward Dtech, PCB by Girts, Erica Synths.
