Mark as solved?

Could you possibly post a pic of the board with offboard connections as well? This board has peculiar wiring, so it could be just as simple as that. You also have to cover the LDR/LED assembly while testing the circuit to prevent the intrusion of light other than the LED. When you say...

My fair Canadian brother, It's totally all good. Sorry for being unclear, I don't know how to do the drawing on pictures thing. I don't think I'm helping much either, but I am all in for helping my bud figure this out, and since I can't really speak to complex circuit analysis and diagnostic...

Well if you can see it on the 5817 (bottom pic) alright, I still can't. [edit: not bottom pic, that's the 4742; the 5817 is to the left of the rightmost switch. I don't see a stripe at all] IC 4 is upside down?

Right, but then the daughterboard wires are referencing the wrong/opposite connections on the main board. Like -15 is going into +15. No? I mean, my spatial reasoning can't be that off, right? I'm specifically looking at the pic in post 16 showing the full assembly and daughterboard...

Everything looks okay component and orientation-wise for the electrolytics, but I didn't check resistor values--except I can't see the 5817 stripe on either shot--could that be it? If not, I'd doublecheck that the Traco module is a correctly compatible one. Maybe check for continuity between...

Well, you could just go troubleshooting ham on the breakout board since it's so limited. I would do ALL the probes (except audio) Can we get closeups on both sides? My guess would be something polar that's flipped or off-spec --maybe even the Traco module--maybe a trace or short issue...

Mine is wholly dysfunctional around the compressor. Like not-good signal grodyfiying distortion dysfunction. But that's a totally separate thread... Go, go, mybud, go!!

ooooohhh yeeeeaaaahhhh... good point. I have a looper pedal that just doesn't work with some plugs because it needs too much juice.

I see a lot of missing ICs, resistors, wiring, switches and jacks. Could have something to do with the lack of signal hahahaha If it's any consolation, my L4 works, but definitely developed issues--in the compressor section, I think. I'm also not looking forward to wading into those waters...

Having built many of the Marshall emulations here, I'm curious to know how it stacks up to the PAL 800/M 800

See, it's cool because he used the French word.

Si t'es content, je suis content.

SWEET

Feral Feline I told you NOT to tell about that! Damn! How can you have a conspiracy when everybody knows the details???

ditto. Lifted pads for me usually had desoldering involved.

Very nice build and 80s horror aesthetics. Yeah, I think "overdrive" for this pedal is a bit of a misnomer in my mind. "Chug maker" would be a better name for it, or just "boost." Doesn't really do much spectacularly on its own, needs to feed another distorting pedal/amp. "Lycan.... the...

I really like this circuit A LOT--flexibility, beautiful decay, and tones abound

@Randman , do you know PCBGuitarMania? I think you need to check out PCBGuitarMania modulation circuits hahahaha...

I don't disagree that supplying the missing schematics for circuits that are chronically problematic is a good idea, though... it might even be positively beneficial. Low Tide and Acrobat, for example.
