Just opened this up to give it a good cleaning, looked like someone puked on top of it and it seeped inside. All better now.
To clean this bad boy I sprayed it with a mix of Simple Green and water (25-75), scrubbed it with a nylon paint brush and sprayed it down with clean cold water. Immediately after this I sprayed the entire board down multiple times with compressed air. At this point I would still wait 24 hours to power the Roland up.
Next time I’ll try to remember to get a shot of the board all soapy.
