The BK-600 is one of the LTD Signature Series guitars for Bill Kelliher, guitarist for award-winning American metal band Mastodon. Designed by Bill to provide the wide range of tones needed for Mastodon’s music while being sturdy and reliable enough for his most punishing rhythms and brutal riffs throughout long tours, the BK-600 is based on the single-cutaway ESP Eclipse guitar style, along with a traditional full body thickness and no waist cut. Its 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 BK-600 offers an ebony fingerboard with pearloid “ESP Flag” inlays and 22 frets, as well as binding on the body, neck, and headstock. Its sound is generated with a set of customized Seymour Duncan Distortion pickups, the original high output humbucker with a massive ceramic magnet and hot coil windings to deliver full-bodied rock and metal tones that are controlled with master volume and tone knobs that each offer a push-pull control to split the bridge and neck pickups respectively. Other professional features on the LTD BK-600 include locking tuners and a TonePros locking bridge and tailpiece. It’s available in a distinctively cool Military Green Sunburst Satin finish.

If i want to replace the pots on this guitar, should i go with short or long shaft?

Carl N.

Should be fine with short shaft.

Michael L.

It's not a common color.

I think we may shoot a lot of riffs with that guitar ^^

Carl N.

Best of luck Michael!

Hey Luke, not currently but thank you for your input!

Not sure if I feel duped or not..??  I picked up a brand new ESP LTD Bill Kelliher Signature BK-600 on Black Friday 2019 before Christmas through Sweetwater Indiana.  As I ordered it....It came as expected with the Lace Sensor Dissonant Aggressor pickups...which are the original signature pickup version Bill intended for that guitar and specific Mastodon tone.  Bill Kelliher was here in Vancouver, B.C. December 12/19 a few weeks ago for a ESP promotion clinic at Rufus guitar store.  I was honored to see him and he autographed my guitar on the backside body   

So...the kicker is, now I'm seeing and just learning this signature guitar is now being loaded with Seymour Duncan distortion pickups in it..? loaded with SD can this guitar remain a "signature" guitar of Bill Kelliher...?  Which means it no longer carries his original unique Mastodon tone....and should be rebadged and called a Gen 2 model so buyers can know that there is a difference in tone.

I understand if Bill left Lace Sensor..that's his prerogative.  So should I feel blessed or privileged to own the "original Lace sensor signature guitar version" and it being autographed by Bill...??  How does this new Gen 2 version alter the value or resale value of my Gen 1...?? it worth more or less now..? 

Well...all in all my Lace Sensor aggressor pickups Gen 1 guitar sounds kickass with 12-52 D'Addario NYXL strings tuned to drop CGCFAD.  Tone complimented with a REVV G4 aggression pedal and keeping that aggression tighter with a Fortin Grind.

Hey Tony, artist change their specifications all the time, you shouldn't feel you received less of an instrument because you received one with their previous specification.  I am sure it is worth more now with his signature.  Hope you continue to enjoy it!
