This module contains three individual cowbell circuits based on those in the TR-808. The main differences are pots on the panel to alter the frequencies and input jacks to patch in external signals to replace oscillator #2 of each circuit.

Originally this module was just a joke and never intended for release, but people kept asking when it will be available and it actually sounds quite good. So here you go.

The PCB is quite dense, probably not an easy build for beginners at soldering.

The accent input is tied to the trigger input via the switch tab, probably best to use a gate rather than a trigger to get the sound going, but that depends on what you want to do. Otherwise patch whatever you like to make things happen.
