I'd never heard of these until this morning - and I could not believe the second-hand prices of the original... especially considering the new price of a hand-made pedal from the builder.
It's kind of a Timmy x boutique Tubescreamer type thing - can find the schematic here. Dual tin can opamp is required - hope this is the layout you were looking for.

Gearmandude! I miss that guy man. Good looking out Andrew!
