This was a little tricky to figure out:
clap reverb mod -
replace r376 (47k) with 100k trimpot
This will vary the reverb between full and completely off.
C144 must have the correct polarity.. neg to gnd
you have to trim TM3 to get a handclap sound of your choice
make sure that your noise is trimmed between 100mV and 140mV AC (RMS)
please read the TR-808 Servicemanual, you find there addional infos about Gain (you can change 2 resistors to minimize the gain of the handclap section)
if your Handclap reverb dont work: measure with a scope the triggeroutput (Tranny Q29), you find it too on the R360 and the q69 ( you must have this on both ! )
Cowbell
Range: replace R44 to a 50k trimmer
