Whan I asked that question, it was only to see if there were people outside of those that we usually hear in those threads, such as van halen ,rhoads, or Satriani...
I know art tatum, and some jazz soloists can beat hands down those guitarists everyone talked about, but it was still fun to hear about those fastest guys...
I've seen mac alpine, because he is actually backing Vai on his world tour, and he is awesome...
As for shawn lane, he is said to be the 'art tatum of guitar', because he is one of the best specialists of this pianist in the world... So, go check him out... I really think that he is the fastest though, because not only is he fast, but he plays be bop lines, and not arpeggios, like you can hear with malmsteem and becker, when you slow lane's tapes, you hear a normal jazz tune, whereas you slow malmsteem, what you hear is a warmup exercice...
