This is the guitar that my signature model is based off of, in terms of the pickups and also the neck shape. This has been in my bedroom when I was 19 practicing guitar playing, and Madison Square Garden, and Tokyo, and television shows… this is the representation of all the places I've been. This guitar started in my bedroom, when I had just gotten out of high school.
