Not that these are better than any of the previously mentioned guitarists. But to add a couple:
Buddy Guy, Yngwie Malmsteen, Doug Aldrich(Dio, Whitesnake), Wolf Hoffman (Accept, solo work), George Lynch, Trond Holter (Jorn), Rik Emmett (Triumph), Ritchie Blackmore, Reb Beach, Rick Medlocke, Adrian Smith (Iron Maiden, Bruce Dickinson solo), Craig Goldy (Dio), Gary Hoey, too many to mention.
And I do not think I saw Stevie Ray Vaughn mentioned, may have been though.
Here is a video from Gary Hoey if you may have never heard of him. He is definitely worth checking out.
