Boss OD-3 SubClone

Found this floating around the interweb some time ago. It is OD-3, with tone control, buffering and switching components removed. The original design would be crazy big and undoable (at least for me) on vero. So this WGTP's simplification of schematic supplied by J. Luja more than 10 years ago should suffice. According to DIYSB thread, it should sound very close to the original. Like the name suggests, it's not a clone, but a SubClone. Offering what makes up the OD-3 sound but in a lot smaller circuit footprint.

Here's a Boss Soundcheck clip of the original:
