From the post

For Fuzz Friday here's the coolest Green Ringer + Rat pedal around! (To be fair, it's an awesome combo) The Green Ringer is on a JFET blend and the Rat section is pretty standard. There's also a fairly generic MOSFET boost on board as well, similar to a SHO or Black Eye. This should all fit nicely in a 1590BB with board mounted pots.

As requested, here's the schematic:
