Yeah, fuzz has to be the most variable by far. I generally chalk it up to the circuits being so simple and unfiltered. You can spend the rest of your life going being between different fuzzes and they will all be so damn unique. I am totally with you in the Strat bridge pickup, I never use it except for Gilmour stuff, and he managed it because he had these full tilt dark wooly fuzz faces and Muffs. The combo goes together like peas and carrots. I still have to add a touch of 1.5k on an EQ to get it right I find.
I currently have an Analogman Sunface, which is a Fuzz Face, with the BC109 chip, to mimic the Dark Side era Fuzz Face. But just typing this it's wild to think how much variation there is in these, same circuit but different chip is wildly different. I also have a Sunlion with a Tonebender 1.5 circuit, which is very Fuzz Face like.
I have always considered Muffs their own thing. I have an original Black Russian I've owned since it was new. I actually just got it because I didn't know any better back then, I was just trying to buy a distortion pedal lol. They fetch decent money these days actually. I got the Ram's Head reissue not super long ago, and that was a 100% Gilmour thing.
