There's a little story behind those particular ESPs. Shortly after they started making the Vipers, I did get some Vipers, but I've got three that they made in the custom shop for me originally, and they were a little too close in proportion to the Gibson SG. And I think Gibson said, "Naah, y'all can't make anymore of those" [laughs]. So I do have some Vipers that I occasionally play. I used some in the studio this time, but for the live play I'm just kind of stuck with the old customs I've got. They are real lightweight and well balanced, and they just play well. The only problem is, I've only got three and those are the only three they ever did [laughs]. So I've got to take care of them.
