on this guitar I personally did not see the blemish. However, just because I did not notice it does not mean there is not a small cosmetic flaw somewhere on the guitar. This was sold to us as a B-Stock for a reason where ever that reason is it is small in nature. (see pictures)

ESP LTD BK-600 Bill Kelliher Signature – Vintage Silver Sunburst

Designed in collaboration with Bill Kelliher of Mastodon, the LTD BK-600 is a formidable single-cut powerhouse made for players who demand both crushing tone and refined versatility. The latest version of this signature model features a bold Vintage Silver Sunburst finish with striking copper highlights and multi-ply binding that gives it a high-end, custom-shop aesthetic.

Built on the ESP Eclipse platform, the BK-600 boasts a full-thickness mahogany body with no waist cut, giving it substantial resonance and sustain — ideal for delivering Bill’s punishing riffs and melodic leads. The set-thru 3-piece mahogany neck offers seamless upper fret access across the 24.75” scale, while the Macassar ebony fingerboard with 22 extra-jumbo frets and ESP flag inlays ensures fast, fluid playability.

What truly sets the BK-600 apart is its set of Bill’s signature Mojotone Hellbender humbuckers. Designed to handle Mastodon’s dynamic sonic range, these nickel-covered pickups can unleash ferocious, high-gain aggression or pull back for clean, articulate tones. With push-pull coil-splitting on both volume and tone knobs, you’ll have access to a vast tonal palette, from tight rhythm chugs to shimmering cleans.

Equipped with LTD locking tuners and a TonePros locking bridge and tailpiece, the BK-600 is tour-ready and rock-solid in tuning stability. Whether you’re on stage or in the studio, this guitar delivers premium performance with style.

Comes with an ESP deluxe form-fit hardshell case.
