Well, I checked the IC's-- Pin 5 of the 62 is rapidly fluctuating between 3 and 5 or so volts. Any thoughts? I swapped it out, and it did the same thing with another one

Makes sense. Next step audio probe. My thought is to set the repeats at max and find where in the circuit I stop getting oscillation. Hopefully this will lead me to the buggy component. Could my 62 or 72 be bad? Would that cause the repeats to stop?

So I de and resoldered the pot. While it was unattached I checked resistance-50k. As soon as I attached it that number went back down to 9k.

So life was great until this afternoon. I was playing the sdx this afternoon, currently unboxed. I pushed the repeats pot upward just a tad, and now I am only getting slapback, even when maxed. SO FRUSTRATED. I'm not sure if something else got bumped in the process. I took a voltage reading across the repeats pot and I'm only getting about 9k when maxed. The slam button also doesn't work. I tested both pt's in my rebote. They are fine. Any specific components I should be looking at to start? I'm not great with complicated schematic troubleshooting yet...  If you can offer any wisdom , oh pedal gods, please. I am in need and the next stop is my garbage disposal.

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.

Honestly, i'm loving this thing. I am having one problem. When i'm past 9 or so on the delay pot (quick repeats), the entire pedal goes wacky- almost like mod is turned on and cranked and slam is being pressed on and off. As soon as I back it down to a bit slower repeats it is fine, but not having 25% of the delay range doesn't sit right with me. any suggestions? Thanks!

Hey Guys,

Im finishing up the sdx and i have a question. I only have one on/on SPDT. I have a few on/off/on SPDT's that would fit. IS this an ok subsitution? Thanks!
