Not sure if we are talking about the same pedal, but I assume mine is not the reissue. The three internal trim pots do not affect noise like in a analog delay, just repeats and clock and one that affects mode selection (voltage ladder?). Adjusting either of them makes no difference in the white noise produced.
I'm wondering if this is not the correct forum or sub to post this in since this is DIY forum. Is there other forums that have more activity around pedal repair?
