I like overdrive (and fuzz sometimes), but I don't like the tain up too much. I like chords to ring and to jangle, and I like hearing note definition. Too much gain takes away that beauty! But fuzz makes some nice, thick, sustaining single-note lines.
I use tremolo and chorus sparingly, but they are both on my pedalboard. I like analog (or analog-ish) echo for lead parts. The BBE Two-Timer sounds great, but I can get a very similar sound with my Boss DD-20 in "analog" mode, and that has tap tempo.
Like I said before, different guitars bring the variety. The only thing I ever adjust is the output level on my overdrive pedals, since humbuckers and single coils have different unity gains with my overdrives.
I like a bright-ish midrange crunch sound, kinda like some AC/DC, although I never tried to match their sound exactly.
How do you get your sound? Did you model it after another player?
