Thanks!

Hey Ya'lls
This is my first attempt, simple text (converted for printing) on a white BB enclosure. I thought the size was all done to scale, but they keep rejecting it (wrong size). Can someone help?
Thanks in advance

Hey Ya'lls
I'm getting signal into that "stress" LED, but no sound when blend is all the way delay...getting some analog noise (normal amount) when engaged. The beginnings of my problems start at IC3 pins 1, 2, and 3. 1 and 2 are somewhere north of 14v and 3 is jumping around. 4 is zero, 5, 6, and 7 are at 7.5, and 8 is 15.07...the A side of IC3. Any and all ideas are appreciated.
Thanks

Damn, I did read the pin 1 bit and totally blew thru it.  What chips have you replaced?

All but 2 of the opamps (I've never blown one of those). My readings were all good.

This is just a stab in the dark, but is it safe to say you remembered to use the bi-polar cap in the right spot? I screwed that up last year. [emoji16]
I did, thanks.

Hahahahahhaaaaa! I did! Thank you  I needed that!

So the rest of the pedal is OK, just the overload LED isn't working?  I'd suspect the transistor but you should be able to check LED function with a battery (or supply) and a 4k7 resistor to see if it lights up.

Well yes to the rest of the pedal, sans any output on pin 1 of IC1 or 6 and 7 on IC2...I changed the LED...still not getting juice. Thanks for the help

I probably blew out the LED. Would that do it?

Hey folks,
I installed C35 (100uf) backwards and it blew up. Replaced it, and all voltages seem ok (I think) but not getting any output from pin1 on IC1, or IC 2, pin6 and 7 and, usually when you plug the pedal in, you get a flash from the "overdrive" LED, but now, nothing. Also replace C36 and C37...same results.
Thanks!

Thank you!!!

I have a file that used to get accepted at https://jlcpcb.com/ but now gets rejected with "no border" as the reason. Anyone want to take a stab? I'll compensate with paypal, parts, your pleasure. It's a small clone circuit with 3 depth selections.

Thank you!

Awesome build.

Insane build, Jimi. Looks great.
