808 Bass Drum

DIY 808 Bass Drum for Eurorack Modular Synthesiser

This is an 808 Bass Drum module design based on the original circuitry. Original Japanese transistors are changed to BC series transistors. Addition to the original design is the pitch adjustment and also an optional resistor is added for longer decay. It also has adjustment for tone, decay and level.
The front panel is also made out of PCB and screen printed by hand. Size is 8HP. Check out my other listings for more DIY and build eurorack modules.

Here is a video of the module in action:
