From the post
After checking a few things out, this turns out to be slightly modded Maxon DS-830 (thanks johnk for noticing). The 47p, 10n and 180n cap values are measured on board, so i'd suggest using sockets for those and see what values work the best for you. Anyway. This should be safe to build.
Playing around with the original, this may be one of the most underestimated drive pedals around. You won't be saving any money building one for yourself, but this way you'll be able to tweak the gyrators and clipping diodes to suit your taste.
