Pretty amazing stuff that may be of interest. Vittorio Camardese demonstrating advanced tapping techniques from way back. Be interesting to know just how far back this does go; I would have thought plucking and tapping are synonymous. I believe there was a vaudeville entertainer called Roy Smeck who also used tapping techniques on hawaiian guitar and banjos. But it seems safe to say that tapping was around long before it was invented in California in the 70s. Does anybody know if any classical players used this technique possibly much further back?
