I can't post it I'm afraid, it's one that has been requested is kept private. Apologies about that but this has been the case with a few layouts I've done on here, and I want to respect the wishes of the contributor.
ahh, i see what you mean now. i compared marks and johns, which have all the wire connections in the same places, and it appears that the ground should be below treble 3 on the right side (row 3 on the right).
I probably find the error on John layout.
The 100K resistor next to the 100uF need to be on line below next to the other 100K. It's the biggest error.
After I don't know if it's a mod for more volume: on the left it's 47K/10nF on john layout but on the original it's 4,7K/47nF.
The one you posted it's absolutely correct, John seems to have corrected, before i get the bad layout all the time when i clicked on the link and after press F5, i see the good one now
