Am I watching a completely different video or something? I don't reckon this guy has had classical training and I don't know why you think he has? Just by watching his left hand technique you can see that he hasn't, speaking from experience. Don't get me wrong his playing is excellent but just because he throws in a few harmonic minor scales and arpeggios doesn't mean he was a classical guitarist. Most classical guitarists struggle with electric I noticed at Uni because classical technique is strict. Anyway you don't need and I certainly wouldn't recommend Classical guitar lessons if you want to play like this, I did a degree in classical guitar and it made me quit playing for 7 years.
