I get more requests for these mods to the DR Rhythm than anything else, and well, i finally found them. Originally from Dave Magnusons resonant frequency site and tweaked a little by me.
Boss DR110 Tone mods;
all potentiometers linear unless stated
Kick Decay - Replace R70 with a 1k pot (try something smaller/and maybe logarithmic as mine has a lot of travel to get to the sweet spot)
Snare Snap - Replace R81 with a 47k pot
Snare Impact (tune) - Replace R76 with a 100k pot
HI Hat filter - Replace R12 with a 1k pot
HI Hat Decay - Replace R20 with a 1M pot
Cymbal Filter - Replace R16 with a 1K pot
Cymbal Decay - Replace R44 with a 1M pot, in series with a 1K resistor
Clap Pitch - Replace R114 with a 47K pot
Clap Decay - Replace R113 with a 100k logarithmic pot.
feel free to share around and let me know what you discover, more 110 mods here,
and no i didn't do BD pitch, should be easy enough to find with some poking around :#
