Will try jumpering the connections in that area and see if I have a broken trace maybe?

Yes, I thought that last night, will change to a plastic bezel and see what happens. That got me on the pro 10 build too, LEDs very close to other components and was shorting on the bezel!

Thank you, I seem to have gain on only a few components, this will help greatly!

Does anyone have a schematic I can follow while I'm attempting to probe this one? There isn't one in the build docs

getting me a test platform next time is order some pcbs. Should have done it a long time ago

Ok, effect works when out side the box. Nothing real obvious as to why it doesnt work in side the box. If anyone is out there reading this thread, is the DC jack to close to that top transistor and charge pump? Or is something just shorting when its in the box?

I thought I had swapped out the ICS, I'll try again. I have no audio at R13 and r14 and no audio at pin 7. I will pull it out of the box and investigate again. I feel like I'm getting closer

I am doing some probing. I have audio on pin 6 IC 2, but no audio on R13 and R14. I have audio on R16 when the stages switch is in one orientation and not the other. I have audio up until R13. I have audio on R17, R27. I haven't checked capacitors because they are under the board and it is in...

I have no audio on any of those postions. Interstingly, the screeching does not exist anymore, but there is no sound when the effect is turned on. It's been in the box this whole time, hoping it would be an easy fix. I will endeaver to pull it out and test it out of the box and re-flow all...

Haven't had a chance to audio probe yet, couldn't make noise, tried a 1044scpa and same thing happened so maybe not the charge pump?

I'll start probing. I use the sockets on transistors because I have been duped before by fake transistors and felt like it was easier to sort out if they were socketed. I don't particularly love the sockets. They saved me on the xc phase build I've been troubleshooting though.

I have continuity in all of the above areas. IC 1 pin 7 has continuity to stages switch when switched on way, but not the other. Is this correct? It has continuity with the script switch on both sides of the switch

Re flowed all solder joints, still quiet output. Not silent but just a bit lower than unity when all the way up, tried different op amp too

Tried the charge pump upside down and no sound at all. Tried the only other 7660 I have and the high pitched noise was present but I also got sound through and you can notice a difference when pots are turned. When you touch the charge pump it alters the noise.

Pin 1 4.3v Pin 2 4.3v Pin 3 3.8 Pin 4 0v Pin 5 4.3v Pin 6 4.3v Pin 7 4.3v Pin 8 8.5v

Yeah, it's just the angle the pic is taken from, there is a good amount of clearance there

Ive found them to be fairly reliable too. I do have one more 7660 charge pump, bought at the same time though, but I'll swap it out anyway. I've had a bad run with pedals lately I've built heaps with no problems at all, but the last four have all needed troubleshooting

Will have to check those voltages tonight, I'm off to work

I do have continuity between r14 and pin 6

I have continuity on the pink and yellow areas highlighted, will continue working through the schematic
