If you do a search for "Anastasio" in the Pickup forum you'll find some great info. there. My thoughts are that, because Trey plays a hollowbody, it'll be hard to get exactly the same sound as Trey out of a Strat. That said, for BKP humbuckers I'd look into AIV Mules. If you get them unpotted that might give a little more breath to the sound. I don't play single coils so I'm not sure what to recommend there, maybe Apache?
