You all probably know him, but i just thought id throw him in here for the people who dont.
I think hes made a solo album or two, and a couple of albums (Front Page & Manring) with some other guys.
Anyway, hes uses a technique where he uses his thumb to pick and his other fingers to pick on the higher strings.
