Hey,

Here's another weird pedal I never took the time to trace.
Sorry for the middle section of the schematics, it's very messy.
There's no values for the non-polarized caps, but I don't think they're that critical. I'll add them when I have the time to desolder and mesure.
For now, I'd suggest everything at 100n exept C16 which is probably around 1u and C1 & C2 around 1n.
As always, please tell me if you spot a mistake.

A trace I did of a vintage unit for comparison, also a few cap values missing.

Thanks for sharing! It's really cool to have info about both the modern and vintage versions.

Hi, I had a few questions on this post. First, did you ever confirm the values of the missing caps? Also, what are the FB1 and FB2 parts? I am super interested in building this. Thank you!
