I drew that PCB and IIRC there’s one mistake in it to one of the IC connections. I updated it long ago and will repost it (and that whole DIY layout and BOM) here at another time.
Edit: the PCB is correct. I’ll still upload the full size DIY files.
Edit: I just realised we had a conversation about this project ten years ago on the other forum.
I’d long forgotten who you were, sorry. That tracer thread we were talking in coincided with me dropping out of diy pedals for about 8 years. I never did reply to it again. I only started building again last year and I only done two that I needed. I just build what I need these days and don’t experiment much with circuits like I used to, although the interest is still there....obviously, or or I wouldn’t be here.
All good.
