Hello: I have an OD-1 Japan and love it, but its a little loud with some white noise. Can the pots or the guts be cleaned to delete that white noise or should I just be happy with a singing OLD pedal?
I'd pull the knobs off & shoot some contact cleaner the best you can, even pulling off the back & shooting the pots themselves. I'm not quite sure about goin' wild all over the PCBs though.
Borrow an other guitar with humbucker pickups and you can hear what is the difference between the generated noise. Afterwards will become clear what is the rootcause of the noise!
