ESP Guitars has announced that Bill Kelliher of world-renowned American metal band Mastodon has joined their family of endorsed artists.

Says ESP: “But equally big news is that we’re also announcing the introduction of two new Signature Series models: the ESP Bill Kelliher and the LTD BK-600. Visitors to our booth at the Summer NAMM Show in Nashville later this month will be able to check out Bill’s new signature guitars in person. They will be available at ESP dealers later this year.”

“Working with ESP has been a breath of fresh air,” says Bill. “When I first set eyes on this guitar, I couldn’t wait to play this mean-looking weapon of sound. After plugging it in and cranking it up, I couldn’t put it down. What a great piece of work!”

“We are beyond proud to have a guitarist who is as universally respected as Bill in our artist roster,” says Chris Cannella, ESP director of artist relations. “Mastodon is a consistent favourite among fellow musicians and fans, crossing multiple genres of metal with an appeal that’s like no other band. Bill is a great representative of an ideal ESP player. We’re completely stoked to have him onboard.”

The new ESP Bill Kelliher and LTD BK-600 are single-cutaway designs that employ a mahogany body with a traditional full thickness, and no waist cut. The three-piece mahogany neck is joined to the body with set-thru construction at 24.75” scale for smooth and comfortable fast access to the upper frets. The guitars feature an ebony fingerboard with pearloid “ESP Flag” inlays and 22 frets, as well as binding on the body, neck, and headstock.

Bill’s new Signature Series guitars are powered by two of his own signature Lace Sensor “Dissonant Aggressor“ pickups, a sonically versatile humbucker set with excellent dynamic response, sustain, and tone. The guitars also feature locking tuners and a TonePros locking bridge. Both are being made available in a distinctive Military Green Sunburst Satin finish.
