The best guitar player ever......
How about the one who started it all:
Perhaps the most remarkable of Maybelle's many talents was her skill as a guitarist. She revolutionized the instrument's role by developing a style in which she played melody lines on the bass stings with her thumb while rhythmically strumming with her fingers. Her innovative technique, to this day know as the Carter Scratch, influenced the guitar's shift from rhythm to lead instrument.
