Here are some guitar wizards for this #threetunetuesday by @ablaze
Of course there is Yngwie Malmstein making super fast sweep picking riffs. I saw hime live at a G3 tour and the whole concert sounded like this. He is quite fast but doesn't deviate too much from this style.
Here is John Petrucci way back when he was a teenager with an audition tape. Later on he joined Dream Theater who still tours and makes prog rock albums.
Steve Vai is quite the guitar wizard playing all sorts of strange guitars like this three neck beast with extra drone chords. He has the technical ability and puts the best feel into the solos and overall composition.
That's all for now, thanks for looking :-)
