Yep, my first experiences with Sultans bear out what you're saying Prawnic... after only one day, it looks like if I want to "be" SRV, I need to reach for my Sultan'd strat rather than my IT'd strat...
My IT'd strat is still my "favourite" strat tone at the moment, but it has possibly a bit too much oink for SRV impersonations when the other one is sat right next to it :D
