Module is available as a DIY project only.
This Module is a prototype or in a concept phase.
AC version of the YuSynth Simple VCA
The bottom row of three I/O can and probably should be omitted from the front panel, as they are unaffected by the three knobs atop. The gain on this module was rather high and difficult to calibrate (via the trim pots on the pcb.) But I did not use Log pots in my build as suggested for the front panel control pots. So that is likely causing a minor issue with me dialing in the sweet spot when using this VCA. These are simple and useful VCA's with a lot of character. They can be slightly overdriven as well.
