Hi. Nope. None of the above. Several of his contemporaries remarked on his totally bizarre style. He played with his INDEX finger...using it like a flatpick with up and down strokes. One of the pictures of him playing, confirms this if you REALLY look closely. Although he's often pictured playing a Stella or a Martin, Alton Delmore and Clarence Ashley say he normally used a "metal" guitar. Obviously they mean a "National".

He is one of my favourite artists, although sometimes his bass runs just got plain silly!
