Hey guys, I read the tech help suggestions, so I am updating my prior post. I'm new 'round these parts, so forgive the prior post.
I have verified that I have no cold joints, and no unwated bridges. I have tried adjusting the speed in all filter modes and with mods on and off. as soon as I get past 8 oclock or so on the delay speed, I get modulation/crashing noises with some popping. When the delay pot is any lower than that, everything functions as normal. I've only substituted 2 part values- one 18k resistor in place of one of the two 20k resistors. I'm not sure what steps I should take next to diagnose/ fix the issue, because I don't know what would cause everything to work normally until the delay time is sped up. halp plz? Any suggestions would be greatly appreciated.
