DAM GT-73 Graveyard Tramp
A cool sounding Fuzz Face derivate. Note that the value of the volume potentiometer is unknown but we found out that 250k or 500k sounding good. Also, the fuzz control is wired backwards per original but if you want a normal counter clcokwise control, just swap 1 and 3 lugs and use a 1kC pot. OC82D transistor might be a bit hard to come by so try others that suits your taste.

God City Instruments Uno Fuzz
There is two layouts of this one, one stock with one control. Since it begs for modifications I added a second layout with four pots for more control:
- 100K resistor at the output is replaced with a 100k volume control.
- 33k/68k before Q2 is part of a fixed Big Muff style tonestack so they are replaced by a tone control.
- The tonestack itself has a very deep and quite narrow mid scoop so a Shape pot is added to blend in some more mids via 27nF cap.
Stock layout
...and four knob layout.

Mighty Nut - ENGL Powerball Pre Amp Emulator Lead Channel
Schematic and info HERE
I added the" Low Mode" as well hence the additional Mode switch.
And by request, a layout with a Klon buffer before the main circuit.
