One of my all-time favourite songs, but Be Quiet & Drive by Deftones has an amazing dirt tone, still a great reference of mine.
Fugazi has an amazing trick of making their guitar tones just sound RIGHT for the song. Bed for the Scraping has some great guitar sounds and work! Lead @ 0.29 is great!
I'd also like to doff the cap to Christian Hayes of Levitation & laterly Dark Star, his sound is tremendous - a b-side called 'Jay' from the World Around single has my favourite lead tone ever - can't find any links to it anywhere tho!
Dark Star - Twenty Twenty Sound
Levitation - Need for Not
Pretty much anything Mike Campbell has ever recorded: for Tom Petty, for Don Henley, etc. His tone sounds deceptively simple and basic, but is fiendishly hard to reproduce. (Probably because I don't have his hands! )
The Edge - Unforgettable Fire and Achtung Baby (opposite ends of the spectrum, but killer tones)
Ken Bethea - Pretty much every Old 97s album. He's kind of like Campbell. Tone sounds simple, but it (a) just works, and (b) is harder to reproduce than you would think.
David Bryson/David Immergluck/Dan Vickery - Pretty much every Counting Crows album. These three guys intertwine and play off each other so well, each with killer tone and each positioning themselves in the mix that their combined playing (and respective tones) just sound like one integrated whole. Amazing!
Johnny Marr - How Soon Is Now? Because... duh!
Mick Ronson - Again. Everything. Bowie. John Mellencamp. And on and on...
