IN HIS CAREER as a guitar builder, Jon Sullivan has likely agonized over a myriad of decisions regarding the form and function of his eye-catching instruments, but what to call them was never up for debate. “I got my first electric guitar in 1983, when I was 12,” he recalls. “It was a Maxitone, from the Matsumoku factory in Japan, that was a very ’60s, Jetsons-like bastardization of a Strat. I was very excited about it, and I took a Sharpie and signed ‘Sully’ on the headstock. So it was always going to be a thing.”
