Would anyone have a schematic on this
Need to get the value of the variable resistors labeled "SPEED" and
"DEPTH". All the componets on the board have loc numbers except the
pots, they are just named.
Google offered many sites to download operating manual but not the
schematic.
Customer had unit in a proffesional musical repair shop and instead of
just tightening the lock nuts which were loose they broke these two
controls off and then lost them, then claimed Roland couldn't supply the
parts. The pots are standard 16mm size PC mount but I need the values.
Thanks for any info
