After 8 years of playing an F-hole mandolin, I’ve gone back to playing a vintage Gibson oval hole.  I’ve had a 1914 F2, a 1926 F2, and a 1927 F4. The mandolin in the video is a 1919 Gibson F4 that was refinished by Gibson in the late 1920s or early 1930s. Whenever I play an oval hole, my ears always go back to Jethro Burns. Tico Tico is one that Jethro popularized for mandolinists.
