Triple VCA plus fuzz / distortion

This 8HP module contains 3 VCAs and a fuzz / distortion. The VCAs are similar to the ones used in the NLC Cluster; simple OTA-based but work very well.

The fuzz / distortion is part of the bottom VCA and is a typical diode-based affair, on the PCB the space for these are thru-hole so you can install Si or Ge diodes or LEDs. Turn the Fuzz pot to 0 if you just want VCA.

PCB = USD 18
Panel = USD 20
assembled = USD 160
