Hi folks, but of a long shot but hoping someone can help.
I recently finished a few of Fuzzdog's Disorder Drive's (their take on the OCD). All of them work perfectly except for one, which oscillates in the last 5% of the drive pot's range. The really interesting thing about the oscillation is that it doesn't seem to be the audio signal. It's pristine for the first 95% of the drive range, but then it seems to dump the signal and produce a high pitched oscillation. Playing in this last 5% of the drive pot changes the rate of oscillation.
I suspect either a bad op amp or pot, it's just a bit odd. I've never come across this behaviour before and thought I'd ask before investigating. Has this ever happened to anyone?
