John Mayer performs with his Fender Stratocaster electric guitar in Phoenix on Thursday, Oct. 3, 2013. When asked how the Stratocaster has shaped his creative process, he says, "It's the machine of my dreams. It's the Ford Mustang, the Marilyn Monroe, the lightning rod, surfboard, magic carpet for music."
