Here is a schematic for a nice little Kick/Bassdrum, inspired by the classic twin-t 808 Kick.

It has a combined control for pitch and decay/resonance, a tone control (simple lp filter, just like the 808) and an (over-)drive. This little thing can produce quite some bass and the overdrive adds some harshness to the output.

Gerber files will come in some weeks.

It's the start of another side project. I want to design some drumvoices, that can run off a battery. The batteryholder will be mounted on the back of the pcbs. The kickdrum pcb will be smaller than a creditcard and just a bit bigger as the 9V battery itself.

I added some quick demo jams...
