OP,
Metronome and finger exercises. Rhythm and repetition. There is no other way to develop speed and accuracy. Like the fast guys, musical guys- say Steve Morse, Yngvie, Petrucci- pick every note. Wouldnt worry about the pickups.
Rick- on Yngvie. One the great characters in rock, a complete asshat and a walking cliché (who can forget the comical “unleash the fockin fury” aeroplane incident) my god that man can play the guitar. I watched that video, I’ll give him the benefit of the doubt (because Ive seen him play live) and say that clip was done in one unbroken take. Six minutes of balls out neo classical guitar pyrotechics and I heard one dud note at around 5.27. I think. Utterly amazing. Here he is doing it again, live (this gig could only happen in JPN). No mistakes. Hes a freak. There is whole concert of YJM and orchestra. No mistakes.
