Please listen to jazz guitarist instrumental songs, they can play rock easiely, it's a question of drive on/off. Jazz guitarists start to learn guitar playing from 7 years living. The only thing is that they didn't play rock before and 2 hours to listen what they must do. That's it. Rock guitarists mainly create their experience starting allready from easy rock song covers and then, try to create something like that on their own. Yes, a lot of them have musical theory experience, but if the interest was born in rock, they never be able to play jazz in future.
