for me i'd say:
the guitars on katatonia's "last fair deal gone down" and "tonights music"
dimebag darrells guitar sounds amazing, especially on cemetery gates when he uses the whammy pedal with pinch harmonics
martin farfalla's bass on morningrise and martin mendez's slapping and popping on "blackwater park"(title track)
dino cazares of fear factory (the double pedal play's a big part in his tone)
stephan carpenters guitars on deftones' "the white pony"

, then they change their minds about the song. (its on the Salival box set, as a hidden bonus track at the end)
