3320 VCF (Eurorack Voltage Controlled Filter)
This module is a typical voltage controlled low pass filter design based on CEM3320. It is hand built with good quality components and AS3320 (CEM3320 equivalent). It can create from low rubbery bass to high resonance screaming synth sounds. It is a simple design with audio I/O, CV in, CV amount, resonance and the cutoff frequency. 3320 design was used in the 80s by many synth brands such as Oberheim, Sequencial One just to name a few. My personal opinion is it is an underrated filter design.
