The Request Topic I made for this where Steven Posted his gut shots has gone... it didn't conform to the schematic around as it used a single Quad Op-Amp instead of 2 Duals and had less diodes, might have had a few other differences too.

Anyway, I just made this Draft PCB for it... I can't work out what's going on in and around the trimmer though and there's a few questionable spots anyway, but I thought it was a start atleast to get something going on this pedal.

Overlay & Schematic Redraw for the Other Version to come.

The pictures have vanished from my Attachment window in my profile. I guess that happens when a thread gets Borked. I can put them up again when I get home tonight, but I dont have them here at the office.
