Mark Morton discusses how he gets his iconic amp tone in Lamb of God, the MESA/Boogie Badlander 100, and his signature Les Paul
Fresh from the launch of his signature Les Paul™, the acclaimed guitarist and solo artist Mark Morton from Lamb of God sat down at the Gibson Garage Nashville to discuss his relationship with MESA/Boogie® amps, delve into the secrets of what he looks for when dialing in his iconic Lamb of God amplifier tone, and the amps he’s been using on the Into Oblivion album and tour.
In this interview, he talks about how he has expanded his rig, which now includes the MESA/Boogie Badlander™ 100 alongside the MESA/Boogie Mark IV™, and how, after years of experimenting with amplifiers, tubes, and gain structure to nail his iconic sound, it’s become a key part of his rig.

What amps does Mark Morton use in Lamb of God?
As he discusses in the interview, Mark Morton’s live amplifier rig has evolved from his MESA/Boogie Mark IV to incorporate the Badlander 100 as a central component of his tone on recent Lamb of God material. While he continues to use the Mark IV—and still loves it, citing it as one of the most versatile and expressive amplifiers he has played, particularly for its midrange shaping and gain response—the Badlander offers a different sonic quality that is more aligned with what he needs for the Into Oblivion sound.
“I think what the Badlander does, in a lot of contexts, was a real gain for me sonically, because there’s such a usable low-end presence to it,” explains Mark, describing the shift away from his long-time use of the MESA/Boogie Mark IV.
While he still considers the Mark IV one of his “favorite amps ever made,” particularly for its gain response and the way you can get such a wide range out of the mids, which he describes as “untouchable,” he found that the Badlander offered a different kind of control that better suited his current needs.
As he puts it, the Badlander retains “wonderful, very present mids,” but crucially delivers a low-end response that is “so usable and so not saggy, and it doesn’t fall apart on the bottom end.” This is something he notes is essential for Lamb of God’s fast, heavy riffing style. Paired with a Rectifier 4x12 cabinet, the Badlander provides the tight response and sonic consistency required for his style of playing on stage and in the studio.
Why Mark Morton loves MESA/Boogie amps for the Lamb of God tone
“The Badlander has these wonderful, very present mids,” explains Mark. “The low-end response is so usable and not saggy, and it doesn’t fall apart on the bottom end.” That balance of tight low end and articulate gain response is central to how he shapes his sound with Lamb of God, and it is a key reason why the MESA/Boogie Badlander 100 has become a core part of his rig.
Known for its controlled low-end performance and strong midrange presence, the Badlander allows Morton to push low frequencies without losing clarity, ensuring that fast, palm-muted riffs and those signature pinch harmonics are front and center.
The Mark IV was produced between 1990 and 2008 and is now an icon of Boogie tone
From the Mark IV to the Badlander 100
While the Mark IV remains an old companion, the Badlander has become the go-to for Mark's live rig and studio recording setup. Mark Morton’s relationship with MESA/Boogie dates back to his early years as a guitarist, when he first encountered a Mark IV in a local music store and immediately connected with its sound.
“I plugged into one, and I didn’t want to leave. It just did everything I wanted,” he recalls, describing the moment that would shape his tone for years to come. That amplifier became a core part of his rig and has been used on many Lamb of God recordings. However, he feels that the Badlander better suits his sound at this moment in time.
“The first thing that grabbed me was the low end. I can really now push some low into it and still have it have a gain structure and a gain response that is usable for me.” He says. “I find it to be this unique blend of the Boogie Rectifier family with that emphasis on low end, but it also does this very old-school throwback British kind of mids.”
Mark Morton’s Signature Les Paul
In 2026, Gibson partnered with Mark Morton on a signature Les Paul model that pairs stylish hardware and a classy AAA quilted maple top with modern features designed for guitarists seeking a high-performance guitar ideal for metal. “I’m thrilled with the whole process, and it’s really exciting to put it out into the world and see that it’s already been so well received,” Mark says.
The Gibson Mark Morton Les Paul Modern Quilt was designed in collaboration with the acclaimed guitarist and captures the precision and power of his playing style across both Lamb of God and his solo work, with features specially selected for both comfort and expression, including an AAA quilted maple top with Translucent Ebony Burst Satin finish complemented with chrome hardware, Grover® Rotomatic® locking tuners, and a truss rod cover bearing Mark’s signature.
The guitar is loaded with two Mark Morton signature humbucker™ pickups, handcrafted by the Gibson Pickup Shop, each with unique qualities. The rhythm pickup features moderate, Patent Applied For-style windings with a ceramic magnet for clarity and punch, and the lead pickup, which Mark describes as a “flamethrower,” offers higher-output windings and a ceramic magnet for added presence and power.

Talking about what the release of his signature Les Paul meant to him, and his love of the Les Paul in general, Mark said, “It was the first guitar I ever fell in love with. It’s such a historic guitar. It’s so synonymous with rock ’n’ roll and so many other kinds of music, but for me it was always the quintessential rock ’n’ roll guitar.”
