Took the gain pot mod out of both and soldered the 100k trimpot back onto the PCB. both work fine now. Even with the momentary mod. Well, that was a fun adventure. Sorry for all the troubles.

It all comes back when in the enclosure. Both boards, both with the same problem. I will probably just revert them back to unmodded so it's not a complete loss except for the predrilled enclosure. Pretty sure they will both work fine once I take off the external gain pot mod as that's the area...

I've tried 2 chips. I have a few more. I'll give it a whirl. Ok so, upon further testing I was wrong. The feedback knob seems to work normally as far as repeats are concerned. Now I'm not sure if the one repeat thing was happening before! I swear it was though. Actually, the volume...

I managed to dial the feedback knob to get more than one repeat, but it's like a hairs width turn away from self oscillation.

Ok, so I didn't try it inside the enclosure but I'm pretty certain it is the same problem as before because I get the same squealing radio interference upon touching the gain pot. Good news is that rearranged momentary mod works though.

Phew glad I asked. It's the right pad. ? Ok, going in.

So, like this? Specifically, how the pink and green wires are connected to the trimmer.

On it! Yeah, the WF mod seems just the ticket. After my tea though ☕

My pleasure! Yeah, ordering the right part might be best though 86k is dang close and it's not going to be difficult to remove since the pots are out of the way. Do it until your 82's come? It'll be hard for anyone here to say what would work best in place of that 82k since there is no reference...

Bummer! But you are on the right track with series. Series or parallel would work. Parallel is both resistors spooning each other and you'd need to add two together that go much higher to get it drop down to 82k. IDK, maybe around 350k total between the two? Someone smarter would have to chime...

Not sure but I bet a Strat going through one of those bad boys into a dimed Marshall would rip my undergarments off. In all seriousness, try Tayda or Mouser for a trusted source of components.

I'm taking a break from this for a bit. I will definitely come back to trace that schematic with my probe but I need to walk away for a spell. Haha. I just finished populating a second board. This time I ran a standard 3PDT and just ran the external gain pot mod. For the momentary oscillation...

You're a gd champ!

Yes, but no looper pedal for signal generation. Also, I'd need to know exactly where to follow on the schematic and that would be difficult as I don't know what I'm doing. Why did I build an audio probe then? lol

OK thanks. 1: 4.2v 2: 4.2v 3: 4.2v 4: ---- 5: 4.2v 6: 4.2v 7: 4.2v 8: 8.4v

Same here. For me, I just stop after this

Resistance between 1 & 2 looks ok: around 47k to 142k. Pin 4 is grounded Forgive my ignorance but I need a refresher on this. Been a while. Black lead anchored to ground point, then red lead to pins 1 through 8... but what do I set my meter to again? Just did. Same prob.

That's pretty!

The bridge pickup. Really, it only makes position 2 & 3 out of phase or normal. The rest are unaffected by pushing it. But it's pretty great and I'm happy with it being a tiny button in easy reach.

I imagine there are a few different ways to do the fancy switching but here's the wiring stuff I used: push button switch and megaswitch I didn't buy the push button from that site though, can't remember where but from somewhere cheaper. Oh, and I needed some Devcon plastic welder that I didn't...
