My best guess is that it is a Boss OD-1 clone with some added mods. It is very bright and LOUD (guess the taper of the volume pot :))

Pictures from Discofreq's database
(when some more pics are needed, please ask!!)

Enjoy!

Then check it again. And keep checking till you figure out why your drawing is wrong.
Sorry. Plain out of planes.

Of course you're right!

Problem was the notation on the print; on the top side there are markings for the B / C / E that are completely wrong. I didn't check those with the datasheet

Beginners fault :)
