If you ever want to hear a master at economy picking check out Tommy Tedesco sometime.
You've probably never heard of him but if you've ever watched any tv shows from the 80's, you're pretty much guaranteed he did the guitar on the theme songs. ie, Happy Days, MASH, Colombo, Charlies Angels, Three's Company... and movies like Godfather, Poisidon Adventure...
If you ever come across a show called Fernwood Tonight, he's the fat guy sitting perfectly still with a cigarette hanging out of his mouth. Meantime he's playing these incredibly fast runs that just blow you away.
