I bought A Jeff Healey video. HIs solos really kick, like Hendrix only faster and cleaner. What is bizarre is the way he plays- with his guitar on his lap and his left hand playing over the top in a fashion that allows him to hammer on with his left hand thumb for extra stretches. Does anybody know of anyone else who plays this way? Is it worth the hassle of re-learning shapes? Are we guitarists depriving ourselves by not being able to use our left-hand thumbs for more than occasionally hooking the low strings.
