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 replaced with BC series transistors for reliable performance. Adding to the functionality, it features adjustments for pitch, decay, and level. For extended decay options, a jumper allows you to easily adjust the circuit's decay time. This expanded control lets you tailor the sound of your bass drum with even greater precision.

The front panel is also made out of PCB and screen printed by hand. Size is 8HP.

Here is a video of the module in action:
