Rig Rundown: Gwar

When GWAR stomped through Nashville with the goriest gear of all, we had to take a look. PG’s Chris Kies caught up with the band at Marathon Music Works to hang with Grodius Maximus, Bälsäc the Jaws ’O Death, and Casey Orr (aka Beefcake the Mighty). The band rolls cab-free, armed with a stack of dangerously signature gear.

Totally Radical

Grodius Maximus’ rig is all about spectacle, aggression, and controlled chaos—designed to sound less like a guitar and more like a “big crazy animal.” His primary instruments come from Radical Instrument Products in Salt Lake City. His go-to is pointy, pink, and equipped with a locking tremolo and a single humbucker. He also carries a gold neck-through model loaded with a pair of humbuckers and a coil tap.

Inspired by Buzz

Rounding out the guitar lineup is an Electrical Guitar Company instrument—something Grodius was turned onto by Buzz Osborne of the Melvins. That guitar features dual humbuckers and a Mastery bridge, adding a slightly more refined edge to an otherwise savage setup.

Dark Favorite

Grodius calls the Orange Dual Dark 100 his favorite amp of all time. While it’s not being used onstage for this show, its DNA is still present via a Kemper, which houses a model of the Dual Dark that anchors his core tone.

All Sorts of Nasty

Effects are where things get truly unhinged. On his rack, a Line 6 Filter Pro handles “all sorts of nasty tones,” while a lineup of Bananana Effects pedals sit in reserve, ready to be unleashed when needed. Switching duties are handled by a Voodoo Lab Guitar Audio switcher, and he also shows off a Death By Audio prototype, alongside trusted staples like the DBA Echo Dream 2 and DBA Robot.

His actual pedalboard is deceptively compact but vicious: a Boss Chromatic Tuner, a Line 6 FM4 pedal, a Hotone expression pedal, DOD Gonkulator, Bananana Mandala, and an MXR Carbon Copy Bright, all powered by a Voodoo Lab supply.

Bälsäc the Jaws ’O Death - Blue Beast

Bälsäc’s rig blends modern metal precision with an openness to conventional and unconventional tools. His signature Schecter Bälsäc Blue Jaw model—soon to be released at what he jokingly calls “an exorbitant price”—is constructed using material from his actual costume. Finished in Antarctic crackle, it’s loaded with a pair of blue Fishman Fluence pickups, delivering clarity and aggression in equal measure.

Non-Metal Vibes

He also relies heavily on a Schecter PT Custom with a purple finish—a T-style guitar that initially raised eyebrows. “It’s surprising how much I love the PTs,” he admits. “It’s such a non-metal shape.” The guitar is outfitted with Fishman Fluence pickups and an Amptone XY MIDIpad, which wirelessly controls his Fractal Axe-Fx III.

Modeling Rig

The Axe-Fx handles amp modeling duties, often dialed in to a Mesa/Boogie-style sound. He also rocks the familiar purple Line 6 Filter Pro. Because Gwar performs to click tracks, all patch and effect changes are automated through Ableton, keeping everything locked tight.

Chaos via Kaoss

Bälsäc’s pedalboard is deep and experimental: a Chase Bliss Onward, Death by Audio Robot and Disemboweller, and a Meris Ottobit and Hedra. In the rack, he keeps a Korg Kaoss Pad, EarthQuaker Devices Data Corrupter, and an EHX C9 organ emulator, allowing him to blur the line between guitar, synth, and noise weapon. He even uses a Moog Theremini as an expression controller, further expanding his sonic vocabulary.

Casey Orr/Beefcake the Mighty - Slim Nikki

Handling low-end duties behind the scenes is Casey Orr, who you might better as Beefcake the Mighty. His primary instrument is the Schecter Casey Orr Beefcake Bass, which shares its electronics with the Riot 4, but features a Nikki Sixx–style body, slimmed down for comfort. The bass also sports a thinner neck, along with 24 frets, a kill switch, and a pair of EMG pickups—a combination Orr describes simply as “super comfortable.”

Backpack Rig

On the amplification side, the cornerstone of Orr’s sound is the Darkglass Alpha·Omega Ultra, which he calls the “missing link” in achieving the bass tone he’d previously been chasing—aggressive, articulate, and perfectly suited to Gwar’s controlled mayhem.
