This is an all analog synthesizer module used to alter the timbre and create new harmonic content. It consists of two identical full-wave rectification circuits, which can be used seperately or one cascading into the other. Each circuit has a manual bias offset as well as external CV that can be used to offset the bias.

Demos, build documentation, drill guide, are available here.

Unfinished panels are drilled by hand in my garage, they are bare aluminum that may be scratched.  They are intended to be painted, etched or otherwise finished later.

Pre-Assembled Modules are built after the order comes in.  Build time can be a few days or a few weeks depending on what parts I have on hand.  When ordering, please leave a comment at checkout if you have preferences on what color(s) the panel is painted.
