TL071 was a typo, was thinking 072. In any case that’s sorted!

Ok, you’ve got better eyes than I do, that totally nailed it

That it is, good catch

I went over everything, nothing's out of place and eveything works. But its definitely audible even in dry that there's a volume drop, and checking levels in my daw definitely confirmed it, it's about half as loud. What's weird is that's the ONLY issue. I might just chalk this up to "meh, that's...

i'll try that then! thanks

just finished checking everything, everything seems ok. this one is really leaving my head scratching

Had a go switching out the bbd, still having the issue. I have a hard time with modulation schematics, could you point me in the direction of the part of the circuit that takes care of make up gain?

I think so, I’ll try that

Hey! Thanks for your response! I gave it a shot, ticking went away after moving the wiring. Still having volume drop tho. I decided to plug it into my daw to get a visual, and it’s not far from being a 50% drop. It’s odd because it sound great

Hey gang, just fired up this build, everything is working fine, waveform works albeit a percivable clicking when internal leds are engaged, read that a TL071 could fix this. But my question is concerning a volume drop, everything i'm reading is saying that it should compensate, but i'm hearing...

3 to the adjacent resistor

Alright! Switched the type of charge pump, and had a spare 4558 lying around. It worked, but after a while the sound would fizzle out, until i jiggled the op amp at IC1. Reflowed, same. Let it play like that (running a loop of guitar into it), and bridged connections on the op amp to adjacent...

I’ve ordered new charge pump and tl072s. Everything else checks out. I’ll keep you posted

Continuity test checks out

The 7660SCPAZ is a direct drop in? With the solder connection at the back?

Cheers, will check this

What I don’t get is that it worked great, even boxed, and all of a sudden just went back to that oscillation, and I can’t bring it back. It’s definitely something power related, because when I unplug it you hear the squeal « power down »

All that flux has been cleaned since Here’s a bigger angle

Scratch that, worked for a hot minute and was the best distortion I’ve ever played, then totally crapped the bed, started doing the same thing again minus the overheating chip

Resolved, bad ic. Popped one in I knew to be good from another build and it came to life
