Generous Reddit member sent me this Breakfast Audio PCB. It looks like a clone of an Ibanez version of the Super Fuzz. They threw in stickers to, awesome!
I had not heard of this circuit though I was familiar with the Super Fuzz. I found this discussion over at the DIYStompboxes.com forum.
Physically the board is wider than a 125B so it probably needs to be built into a 1590BB. You might be able to get this into smaller box in portrait orientation.
