I'll nod to some classics for the first three:

Clapton's "Woman" tone: While My Guitar Gently Weeps
Eddie Van Halen's "Brown Sound": Drop Dead Legs
Andy Summers (the Police) wet chorus/dry echo: When the World is Running Down . . .

My latter day fav's have been:

King's X: Gretchen Goes to Nebraska
The Deftones: White Pony
Kyuss: Gardenia (Welcome to Sky Valley)
Incubus: Circles (the Incubus guy has tons different tones)

I'm sure I've forgotten many more of my favorites, but for my judgement, Gretchen Goes . . . has got the tastiest crunch of them all.
