Just bought a Chaos Drive at the Baltimore Pedal Show. Sound fantastic through both my amps playing a Silver Sky. Les Paul is next.

Ic1. The pedal still does not sound that good as there must be other issues I haven't looked for yet.

Actually, at the end, AI had the only solution that removed the buzzing. It was a long road that also showed its limitations. It can analyze small snippets of a circuit rarely wellbeing not the whole thing.

Thanks. It's worst with a guitar. A test tone isn't too bad. I'll give the 100u a try. The buzzing stopped with the .1 cap from pin 3 to ground. I'm not thrilled with the sound so making some changes can't hurt. Just a note, chatgpt kept referring to VREF all along and once I asked the...

Yes of course, but is was an obvious and easy thing to check. The signal on one end of C12 was fine but on the other it went bad. No change. ChatGPT then wanted to look at the voltage section and zeroed in on C6, the 470u cap. It suggested changing it out which did not work. Then it...

I'm pretty sure that may be the case. I uploaded the entire schematic yesterday and it's analysis made no sense as it had connections between parts at opposite ends of the schematic. I do agree with it that the problem may be centered on C12, 2u2 cap. I still need to switch it out.

You're right As an experiment I uploaded the shcematic section coming off IC.2 pin 6 to chatgpt and asked what the culprit may be. It correctly identifies all the involved parts and it's first suggestion was a bad 2u2 cap in that area. I haven't had time to try it yet.

Apologies for the snarky comment I deleted today. The information in the extensive post, I already know. I just wondered if I missed something or if a more useful board layout existed. There is something wrong with, I think, a supply of 2u2 capacitors as the nasty buzzing still exists...

Awesome! Thanks

Thanks! I have isolated the problem (loud buzzing) to a section of the schematic, coming off pin 6, but want to make sure before I start replacing parts.

I'm debugging a Derailer and I must be missing something obvious. Since the board and layout diagram identify parts by value how does one find a specific part on the board when there are multiples of a single value. I think I have an good idea due to proximity to other parts but I can't be...

I used to put a lot of parts on the board u til I had a rash of problems because I missed soldering them.

When I bought a guitar from Sweetwater I asked for an extra bag of candy to keep my wife happy. It worked.

Can I assume that C100 is a 100UF electrolytic cap? It's not on any build document but C14 is and it's 100uf. And D100 is a 1n5817?
