IMAGE 0792 looks to be a bad solder joint on the switch.

Got some pictures here.

In distortion mode I get signal on lugs 2 & 3 of the sens pot which serves as the volume pot for the fuzz. As I turn the sens pot CW the signal increases on lug 2 of the sens pot. As it should (I assume}. lug 3 sounds so much brighter than 2 (better to my ears). nnno clue now what to do with...

An update. I audio probed the circuit in envelope mode and since I don't know I gotta ask. I did not get any signal on either side of d2/3 No signal on either side of R11 No signal either side of C5. I've got continuity on both sides of the switch ok so I flip the switch to dist/fuzz I have...

Thank you thats the kind of info I need Got a jumping off point now thanks again for sharing.

Thought I had it figured out but. Nope My low baller works in clean mode but not in fizz or distortion mode I checked the toggle switch and it has continuity both ways I guess its time to pull out the audio probe.

I finally got my Lowballer to work one side of the toggle (the clean side) and silence the other side of the toggle. Happy with it so far. Probably start with Captain Obvious's suggestion of the toggle switch . Still another cool PedalPCB build knocked down This seems to be another pedal...

Once again my lack of thoroughly checking into something BEFORE I ask or post has gotten us here. I (we ) can move on now from the openhaus since I found a very nice layout. title says original layout but I am not positive if it is or not doesn't matter to me its a working one

Thanks all for the insight. Unfortunately changing the charge pump to spca only quieted it down so Ill try a scpaz and see how that goes I don't recall where I found the mod might've been here on this site but here's what I have . I believe it was supposed to help with the whine .

I built Sabrotone's Lighthaus. Absolutely love it. I did not have the 2n1306 or 8 transistors which are germanuim. I can't remember where why or how I acquired the one's I did use which were 2n2369a. These are silicone. I know I never compared datasheets between the 1306 and 2369a would'nt know...

I have a pedal. It passes signal in by-pass it does not when engaged. It has a high pitched squeal that can be adjusted moving the pots (i.e. volume pot ,response pot etc. led's work as they should. but the squeal is pretty loud and always there. I suppose I should mention the build I'm asking...

The build docs call for TC1044scpa I have a 7660cpaz and although it powers up and passes signal there is a whine there and I did the 39k resistor and 10nf cap mod. Would using the 7660 be another possible cause for the whine?

Thanks for the quick response. I had reflowed the board once before but decided to do it again and although there is still a hum it was greatly reduced . Thanks again for the suggestions

I think I've got a vague idea for an answer to my question but hoping someone else could confirm or deny my thoughts So I built a Bad Monkey and I get a fairly loud hum when circuit is engaged so I try hunting down the source with audio tracing accidentally touched the output jack ground lug...

Fine people of the PedalPCB forum, I come once again asking for your time. I am having a bit of confusion with the wiring on this one Here is the link to the build docs https://drive.google.com/file/d/1UoN1kGc04fDdSNSP3lPHdxLoPjqy5LX_/view There are four 3pdt stomp switches, the drone and on...

Before I ask, I gots to say, I'm fully aware of how open ended , broad and general this question is , but I'm looking for basic generalized answers . For a kinda generalized troubleshooting thing I'd like to put together. From the ultra stupid (i.e "oh OK the center of vol pot goes to the out...

excel lente!! thanks for the qwik response

building schumann pll it calls for 4017n is this the same as cd4017be or 74HC4017N? or are the last 2 mentioned different chips I'm finding conflicting info and its the last chip I need to finish this thank you in advance

This response/post was an accident. And has nothing to do with nothing sorry about that

How first do you have to hit it you have to room Close to check on her Allen key and hit the Allen key to knock it lives did you research any of this yeah but it is still fucking screwed onto the motor so you gotta do not rocket league you got a new one another joke oh did you already get to...
