This is a tenor banjo I just completed. A friend gave me a large tortoise shell, and I thought it might look good on the back. I put a thin back on the banjo with a 3" hole in the center. I glued the shell over the hole with epoxy. The raised part of the shell (I think that's where the head poked out) sends the sound right at me. I also added a knee rest so the tuning hooks don't jab my leg.
