he used alot of strats on crush but they were vintage instead of the supped up ones on these days and ktf. you could say that crush is the real "strat" album and the previous weren;t.

he just uses guitars as needed i mean he had some sort of gretsch-esque hollowbody on misunderstood for example, he uses les paul on heavier tunes, he uses the 52 tele on saturday night and his own prototype guitars if and when needed live.
