Try the trilogies - they're a great pickup!
Don't forget SRV used EMG pickups on at least one of his strats (used on the Texas Flood album). So as a modern voiced strat pickup, the trilogies will not be too far out. Plus there very high output, so you're amp will get a helping hand!
What you might find is that you have to hit the strings a bit harder, then you'll start to hear the SRV tone come out!
Don't worry yet - road test 'em first!!
