tVCA: Lo-fi transistor VCA PCB/panel set (2HP)


This is a PCB/panel set - it is up to you to source appropriate components to complete the build.

A PCB/panel set for a nice, lo-fi transistor VCA of the type found in old-skool Roland drum machines such as the 808. If you want super high-fidelity sound reproduction then this most definitely isn't for you. On the other hand, if you want something a bit dirty which performs really well with percussive sounds, as befits its origins in a drum machine, then this will have you covered.

It is up to you to source appropriate components and build the module up. This is a good beginners project since it only requires a handful of commonly found components and builds up into something that's (hopefully) immediately useful.
