I shouldn't have to do the research, you made the claim. Maybe you should have done your own research. Anyhoo, I went ahead and downloaded the original 1937 RCA tube book. None of those schematics are anywhere close to a tweed Fender amp.
Get your facts straight...
"It’s my design, performed by Martin who used to work for me and Bradshaw, he would be a little loose on the values for each amp. I still do them and feel I’ve refined it quite a bit since then." John Suhr aka oso@tgp...
Try the Skreddy Lunar Module. It does the FF thing but is fine after buffers. The Boss FZ-2 was a good fuzz, but it was more Big Muff/ Super Fuzz. Didn't sound or respond like a FF at all.
