weird effect! I didn't know how to configure it so I left it with these values for the trimmers
Trim1: 0 - 6.22 - 9.2
trim2: (var) 3.77 - 3.77 4.1
trim3: 5.08 -5.08, 5.08
notes:
- I used a 220pf ceramic capacitor for c6, a 200k trimmer for trim2 and a 0.22uf for c20
-I connected, as with the pearl chorus, r18 to ground
- for Q2,Q3 and Q4 I didn't have any 2n3904, so i used BC549 inverted
have fun!!

Did you use mn3207 or mn3007 on your build? Shouldn't the mn3207 be biased to ground? Nice layout nonetheless!

They can be biased "inverted" like a PNP transistor where the collector is biased to ground.
Ahhh, I gotcha..... That makes sense.
