I'd definately have to say Slash. I spent the first three years of my guitarin' trying so hard to cop his style that it's just kinda there with me now. I've since moved on, but anytime I do some improv whilst jammin' with some buds a dreamy slash-esqe pent run will come out (maybe i should take the "slash" patch out of my RP300 lol, it's the first to load up when I plug the thing in). I'm movin' on though, now I'm trying to tackle Eric Johnson's tone.... it's to die for.
