Roland TR 808 Pitch and Decay Mod

Описание: A short demo for my DIY Roland TR 808 drum machine mod.

Learning from Internet to mod my TR808:
1. Bass drum decay - added 400k ohm + 100k pot in parallel with R164 (still need to experiment and fine tune)
2. Bass drum pitch - replaced the 47k ohm in R165 by a 100 log pot
