Avoid the Boss Fuzz. I don't care what the anybody says digital dosn't manage it, it may be fine for the metal head stuff (and some can manage Tube screamer type boost in a tolerable fashion)
I like the Big Muff pedals (I have made enough of them for myself), but for what you seem to desire you want something with Germanium transistors in it. Possibly (as I think was mentioned) a germanium based booster may also do the business for you.
Silicon transistors are (usually) fizzier & harsher sounding.
