Lets see.....
I had an original Fuzz Face. Got stolen around '72. I didn't think it was great, but it was one of the few pedals that you had back then. You didn't have 247 different fuzz pedals! Replaced it with a Jordan Boss Tone that plugged into the front of the Jaguar. Great for doing Satisfaction and Inna Gadda Da Vita. I eventully traded that for an EEPROM burner many years later. The knobs were broken where the whammy bar would swing around and hit the plastic. I covered it up later with a piece of Erector set with electrical tape on it to protect it.
Got a Fender Blender. Very fizzy. It did fuzz and octave. I don't know where that pedal went. I probably left it at the bass players house.
All told those 3 would probably fetch you 2 or 3 grand today. At the time, I was out about $100 total. Pedals back then were much cheaper!
Most of the time, I simply turned my Guild Thunderbird amp to 10 and if you toggled the 3 way tone switch between two settings, it was almost like doing the jumper on a Marshall. The amp was only about 35 watts, so it would really distort when full up.
Today, I don't use fuzz, I prefer the OD. Klon style and Tube Screamer have been my mainstays, although I really like the Blues Driver that Pete Farmer lent me at PSP. It wasn't so midrangy like a TS. Haven't bought one yet but it will happen. I haven't decided if I'll get the standard or WazaCraft model.
I have a Soul Food, but I replaced it with a NotaKlon. It sounded smoother to me, and was less noisy.
My preference is for a smoother, creamy overdrive, not a harsh biting sound. I like the sustain for soloing.
