From the post

Request, and as it was a quicky I thought I may as well get it out of the way. A tweaked positive ground Fuzz Face using Russian germanium transistors. Being positive ground as usual I would suggest trying it with a negative voltage inverter to supply the -9V and allow you to use a 0V ground and allow you to daisy chain with all the rest of your pedals. Note the required pin orientation and arrange them accordingly.

Info about the original:

Following in the footsteps of Fuzz Face masters Eric Johnson, David Gilmour, and Jimi Hendrix—Joe Bonamassa relies on his Fuzz Face to deliver his trademark searing leads. Tested and developed over several world tours, the JBF3 Joe Bonamassa Signature Fuzz Face is voiced specifically for Joe’s humbucker-driven tone, adding sustain and thickness for a rich, creamy fuzz. This pedal’s hand-wired circuitry is built around matched NOS Russian military germanium transistors for their characteristic warmth and growl. The JBF3 also features classic Omeg pots, housed in a polished copper finish that will patina over time. “I wanted this Fuzz Face to be a pedal that would instantly transform your tone,” Joe says. “It drives you to a different place as a player. Kick on the inspiration box!” Production of the Joe Bonamassa Signature Fuzz Face is limited to a single batch each year.
