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

The charge pumps are from tayda, I thought they would be legit, don't often use those ones though. Will the 1044 work in this circuit? I think I have some lying around

I get sound through when off, but nothing when on. I will check the sockets, they are handy but I'm starting to be suspicious of them a bit lately. I have looked at the stomp switch a couple of times, it is close but I'm pretty sure there is no contact. I don't generally put the back on til I am...

Thank you I'll get on it

Thank you I will check. When I was probing earlier, I'm sure I tried the switch in both positions and in both positions of the switch there was no sound in all of the resistors from R13 to R17. This didn't make a lot of sense to me as I thought it would work in one position not the other. I will...

Just finished a lone king, arrogantly thought I'd be sweet, it's such a basic circuit! However, when on output is lower than it should be, even when all the way up. It does sound like it should though, just a lot quieter. Pulled it out of the box and tried the audio probe and I pretty much...

Hi, bringing back an older one... I'm starting to play with the audio probe. I have sound on every resistor, up to R13. Then going forwards R13,14,15,16, 17 have no sound on them no matter which way the switch is oriented. I have sound on R27 no matter which way the switches are oriented. I have...
