I started with a Gretsch Anniversary Jr., which was the only small hollowbody guitar I could find. I made it a double-cutaway instead of a single. I had a Bigsby installed, and I put in an old mute, too. When you pull a lever, the mute comes up and dampens the strings. I also had a light-activated Theremin installed that I could control with my wrist while I was playing. When I lifted my wrist, the Theremin would be added to the sound.
