Mastodon is pushing the sonic envelope into new metal territory, and we’ve built a unique instrument for guitarist Bill Kelliher that is sure to help in this endeavor. It’s a distinctively arranged 9-string guitar: three strings on the bass side and six on the treble side, with each treble string doubled for that chorused twelve-string guitar sound. The body is a robust double cutaway with a mahogany back, maple top, and silverburst finish, and the ebony fingerboard features pearl block inlays inscribed with the Mastodon logo. Two Seymour Duncan Distortion pickups provide high-output tone while preserving clarity for high-end sparkle.
