In this interview with Guitar Center, when asked about Ernie Ball guitars, Warren says, "There's a couple of things I like about them. First of all, they don't break! I've played tons of different guitars for my whole life. I've gone through like 12 necks from just a bunch of different companies. The Ernie Balls, they just don't break." And on this page of the Music Man official website, it lists the Music Man Axis as one of Warren's guitars.
