Available as an assembled Module and as a DIY project.
This Module is currently available.
Dual AB Switch
The A/B Switch selects between A and B and the middle position of the switch is a "mute", works with any kind of signal (cv or audio) and is bidirectional.
This is an utility module that I made for switching stereo signals, but other uses are possible:
Select between 2 stereo sources.
Select between 2 stereo destinations.
Bypass control for mono signal processing.
Routing control for a single signal.
Panel is reversible so it can be mounted with the switches on the right or left.

These merchants probably sell this module. Huh?
