ART - Gretsch guitars built since They need no introduction. Everyone knows the hollow-body guitars with the Bigsby like the Brian Setzer and the White Falcon models. Their Custom Shop creates awesome hand-painted guitars.
Some of my closest guy friends didn't know what they were. We showed them, and began to play catch with it, and pull on the string. One of them started laughing hysterically. They also stuck a period pad to each other's faces.
