Glad to know that we see the same things If you want, I can send you the archive and you can tweak it at your taste, no problem at all

Thank you for the offer, but I have already finished the Express sch one. Except for minor differences on how we laid things out, they are identical.
Now if Anderton had left the diode clipping section in, everyone would be cloning this circuit instead of the TS... That's why I compared the Lovepedal Eternity to this one several months ago.
i posted some stuff about the freddie fuzz that i had noticed a while back. it's interesting comparing the schematic i redrew or edited to the seamoon fuzz.
pretty much the same circuit to me.
the edited schematic is the top pic, the circuit below is what i believe the wrong schematic that floats around the net.
Interesting. With the exception of adding the blocking diode, the extra filter cap and a very few value changes, this is the Fresh Fuzz. What is the date for the Black Cat? Looking back at some of my old info, I bought the FF in 1972. Don't ask me why I still have that info...
Black Cat started in 1995...but read this, from his page: (bolds by my own)
"The Black Cat OD-1 (a.k.a. Freddie Fuzz) is an original design Fred created based on the unique properties of the OP275, a dual operational amplifier chip made by Analog Devices. The OP275 is a high-quality op-amp that gives a distinctive linear output waveform. The Black Cat OD-1 can go from clean, to slightly crunchy, to all-out saturated distortion. It is unique in that it is extremely sensitive to the guitar; it responds to the player’s pick attack, and like a good Fuzz Face, it cleans up well when you roll back the volume on the guitar. The Black Cat OD-1 has been used by Scott Henderson, Steve Luthaker, Beck, Lyle Workman, Kyle Cook (Matchbox Twenty), and many others."
Looking at those images, my gut feeling is it will be pretty much the same as the first stage, just figuring out where the bite pot ties in. I will have to look at them a bit closer to see if I can make out that part of the circuit. It would help if they had popped the board up from the glue holding it down to the case. It was a similar glue on mine, but after a whole bunch of years the glue separated pretty easily from the board and case. Some kind of silicon sealant.
Using the Fuzz Central Black Cat OD pcb all you have to do is flip the one end of the 100k to the other side of the 430R resistor (trace connected to pin 8 of IC)and you're good to go?
