I don't find anything wrong with what Richie's doing - and if you're looking for something different what about the Any Other Day solo.

I agree that a guitarist defines themselves by their sound, and so you can tell them apart from any other guitarist - the two best in my opinion are Slash, obviously, and Tom Morello, and both have very distinctive guitar sounds, and so does Richie.

But if you're looking for variation, try listening to some Rage Against The Machine live stuff where Tom Morello basically kicks the shit out of his guitar, making some pretty obscure noises while he's doing it.

Anyway, if you listen to more recent bands - nobody does ****ing guitar solo's any more anyway.
