I didn't consciously use any... I set up my amps the other day, and just switched the dirt off.
It's a Brunetti 059 with a Nova System in the loop, a clean Plexi, and a Dr Z Carmen Ghia with a MXR Comp and a BOSS RV5 going it.
I also took the direct signal and added the Waves Amp to it.
That was awesome...well done! One of my favorite players and songs. I've started to learn it on a couple different occassions but I've never had the patience to do the whole thing...you obviously put some time into it.
Killer job! Mark Knopfler knows his fretboard pretty well doesn't he.
I still remember hearing Sultans Of Swing for the first time on AM radio as a kid, loved it.
