Just seems like fuzz kind of lives in its own world. I hear much bigger differences between the flavors of fuzz than I do with, say, flavors of overdrive. Fuzz face, big muff, tonebender, octavia ,etc... all seem to have their own distinct sound and characteristics. ODs do, too, but not to the same degree. They also seem to really favor certain pairings with pickups and/or amps. Like, I hate the bridge strat pickup. But get some dark fuzz on it, and all the sudden its a usable, musical thing. Put that same dark fuzz on a humbucker, and its sounds like a bowl of oatmeal.
My current favorite fuzz, tonebender style, in a mini format. Can get as wooly as I'd ever want, tone knob to dial out darkness, it cleans up superbly with a guitar's volume knob and sounds good with most pickups. That last thing I sent you, @G650, used this with the volume knob rolled to 3-4 w/neck & middle strat pickups.
