Kurt Ballou takes tone very seriously. He’s been on the leading edge of aggressive guitar sounds since 1990, and Converge’s fourth album, 2001’s Jane Doe, is still seen as a game-changing release, with its ferocious performances and masterful production. His sonic temple, God City Studio, is the destination for artists looking to make their rawest, heaviest, brutalist work. Ballou has even developed a gear brand (God City Instruments) that includes guitars, pedals, and pickups, all in the pursuit of turning ideas into art.
During our conversation before Converge’s sold-out performance at Nashville’s Basement East on May 22nd, Ballou dove into his Line 6 Helix spice rack and shared how 30 plus years as a guitarist and in-demand producer have informed his guitar-design philosophy. Plus, he detailed why his goal is to get to a place where “gear doesn’t matter.” And then, longtime bassist Nate Newton joined the fun by showing off his “Riffblaster” setup and how a special P-Bass helps him honor a dear friend.

Construction Zone
For this headlining Converge run, Kurt took to the road with a pair of his own God City Instruments shred sticks. This one is the Constructivist model that has a body shape Kurt has been employing for over a decade. This current iteration has an ash body, roasted maple neck (with bolt-on assembly and C profile), ebony fretboard with cream binding, a Graph Tech nut, and comes loaded with a set of GCI’s Soap Jammers that are stacked alnico 5 humbuckers (10k bridge output/7k neck output). Ballou describes the Soap Jammers as “being high-output humbuckers that have the midrange push of a P-90 that still chugga chuggas like a humbucker.” He’s been using D’Addario strings for over 20 years and has been loyal to the NYXLs since they came out. He currently prefers the Medium Top/Extra Heavy Bottom set (.011–.056) and bludgeons them with D’Addario Duragrip Yellow (light/medium) picks.
Rock 'n' Roll Machine
Here is Kurt’s single-pickup GCI Craftsman that has a chambered mahogany body paired with a wenge top, a maple neck with set-neck construction, wenge fretboard with cream binding, Graph Tech nut and PM-8593 bridge, and it screams—thanks to the high-output GCI Slug Jammer humbucker that has a ceramic magnet and 13k resistance.
Ballou adds that “It’s a beautiful guitar that I just love to play. This is my favorite—just a basic rock ’n’ roll machine, and I use it the most for writing and recording Converge stuff.”
A Floor Smorgasbord
Converge would love to tour with stacks of gear, but they also live in the real world. They understand the compromise a modern hardcore band must make to pull off shows to their high standard, while also staying in the black, so for a few years Kurt has turned to the Line 6 Helix. He says it gives him a consistent, reliable sound each night that can be stored as a carry-on. Another perk is that his setup is in a stereo configuration, and the Helix’s direct-out function allows him to run front-of-house a stereo signal without having to worry about miking cabs (and possible phasing issues) that inevitably happen when mics and cabs get bumped and moved during Converge’s chaotic performances.
For these “Converge Classic”** headlining shows, Ballou operates the Helix in stompbox mode with a “Kvrt Preset V6.” Some of the pieces of the puzzle include a Centaur-style distortion, two separate noise gates, a Tycoctavia Fuzz, a Dual Pitch setting, Ping Pong (turning on stereo delay and reverb at the same time), and a Searchlights reverb patch. All of these are engaged and omitted by Ballou as if they were pedals on a standard board. He does use a phase looper for the song “Eye of the Quarrel” that allows him to play both guitar parts featured on it. His amps are based on modelings chasing a Diezel (Das Benzin Mega) and PRS Archon.
Worth noting that Ballou's grievances on the Helix were addressed by Ben Adrian of Line 6. Here's what he had to say: The gripes Kurt had with the unit can be resolved by issuing an update a while back, the tuner got a "Trails on/off" control, which allows delay, reverb, and looper audio to pass when the tuner is engaged. Also, with an update, "Command Center" was implemented a while back.This allows almost any function to be assigned to any switch in stomp mode. This includes all the controls for the looper.
(**Converge did an album with Chelsea Wolfe in 2021 called Bloodmoon: I. That included the standard four-piece Converge lineup but then added Wolfe, Stephen Brodsky, and Ben Chisholm. They toured as a seven-piece band, then Ballou had his Helix in snapshot mode that had several changes and settings moved automatically by the unit. The band now jokingly refers to their regular quartet as “Converge Classic.”)
Mighty Minis
Rather than employ the Helix’s IR technology, Ballou runs out of the Helix to a pair of Quilter Overdrive 202 heads.
Cat Power
Those Quilters then power a couple of Bad Cat 4x12s filled with Celestion Vintage 30s, giving Kurt all the stage volume he can handle.
Meet Mr. Riffblaster
Nate Newton has been the Converge bassist since 1998, and has always stayed true to the Fender Precision bass. He was gifted this green P from Fender, and modded it by adding in his signature Lace Riffblaster that the company says utilizes “the power of ceramic magnets to create the perfect balance of extreme power and articulation.” He uses Ernie Ball Regular Slinky Bass strings and green D’Addario Duralin Precision picks (medium).
In the Stream of Caleb Scofield
Newton’s other main gig since 2018 has been filling the void of Cave In bassist Caleb Scofield who tragically passed away five years ago. To honor their fallen brother, Cave In has kept Scofield’s P in their gear collection for Newton to use on Cave In recordings and tours. He has it with him on the Converge tour because once their run ended, he met the Cave In crew out in Colorado for their tour behind 2022’s Heavy Pendulum. Newton put in a set of his Lace Riffblaster pickups and noted during the Rundown that “it’s the best-sounding P-Bass” he’s ever played, and, for what it means to play this bass in Scofield’s spot: “It’s a weird thing, especially playing the older songs and using this bass. In a twisted way, it kind of feels like hanging out with Caleb. It feels like he’s there with us, and it’s an honor to play this bass in that band. I cherish it.”
Slim and Husky
For years Newton has plugged into this Orange AD200B Mk3 that pumps out 200 watts, thanks to four KT88 power tubes. It runs into an old Ampeg 8x10 cabinet. A Quilter Bass Block 802 rides as a backup for Converge, but takes the spotlight when he plays with Cave In.
Nate Newton's Pedalboard
The condensed stompbox station still shifts tectonic plates, in large part because of the Nunez Tetra-Fet Drive always being on with Converge. It takes the AD200 from a rumbler to molten-lava erupter. Both the Dunlop CBM105Q Cry Baby Bass Mini Wah and DOD Rubberneck Analog Delay are rarely used with Converge, but both get plenty of usage for Cave In sets. The Shift-Line A+ CabZone Bass sends the signal to front-of-house and offers 10 power amp emulations for additional shaping. The TC Electronic PolyTune keeps his Ps in check, and everything rides tight and tidy on a Pedaltrain Nano+ platform.

If you’ve thought to yourself, “this is the most vicious-sounding record I’ve heard,” chances are Kurt Ballou’s fingerprints are on it. Since officially starting in 1995 inside his parents’ garage and eventually opening GodCity Studio’s doors in 2003 (in “Witch City” Salem, MA, no less), Ballou has chiseled out granite tones for bands like Every Time I Die, High on Fire, Torche, Cave In, Old Man Gloom, American Nightmare, and Kvelertak. (“He brings a lot to the table, and he’s been pretty important in terms of how our sound got formed,” Kverlertak’s Vidar Landa in a PG interview on working with Ballou.) Oh, and we can forget his genre-shaping band Converge, that he’s played guitar in since 1990, co-produced since 2001’s hardcore pillar Jane Doe and been the console captain since 2006’s No Heroes.
As you’ll soon find out in this hour-plus episode, the dude is fascinated with every component of guitar tone. In between recording projects and creating new instruments and pedals, Ballou virtually welcome PG’s Chris Kies into GodCity Studio. In this Rig Rundown, Ballou details his own GodCity Instruments Craftsman Series 1 (something he calls a “simple rock ’n’ roll machine”), provides a crash course on mics (types and techniques), and shows off additional GCI pedal wares—and a few foreign specimens—that contort, mangle, and destroy any (in the prettiest way possible) guitar’s native tongue.

[Facing a mandatory shelter-in-place ordinance to limit the spread of COVID-19, PG enacted a hybrid approach to filming and producing Rig Rundowns. This is the 38th video in that format.]
As you’ll quickly find out, if Kurt can’t find exactly what he’s after, he’ll design something that will get the job done. Above is his first guitar—built under the God City Instruments brand—called the Craftsman Series 1. This one features a chambered mahogany body with a spruce top (“it’s incredibly resonant, snappy, and lively”), set-neck construction (maple neck/wenge fretboard), 25.5" scale, Graph Tech nut and bridge, and a custom-wound, hot Slugjammer humbucker (13k output, 44 AWG). He prefers D’Addario NYXL strings (.011–.052), hammers away with Planet Waves Duralin picks .70 mm (yellow), and Ballou uses a bunch of tunings for Converge, but two of his favorites are “a little out of tune” D standard and one he calls “open Slayer” (C–F#–C–F#–C–F#).
(This isn’t the first time we’ve seen a God City Instruments’ Craftsman Series 1 on a Rig Rundown. For those that missed it, Djunah’s Donna Diane rocked out a wenge-top Craftsman Series 1 in her Rundown in late 2020.)

Need proof that Converge have diehard fans all over the world? Look no further than this Sparrows’ Sons head that was built for (and sent over to) Kurt from their Belarus guitar shop. He doesn’t know much about the circuit, but he notes in the Rundown that early in the signal path sits an active inductor-based midrange boost that sort of acts like a Neve preamp. Another think he mentions is that its gain knob is a dual pot that controls two tube stages at the same time giving the amp a wide range of crunch. (Ballou admits that he doesn’t use it for clean and rather make it a blast furnace of rock.)
The handmade beast (even has handwound inductors) floored Ballou enough that he ordered a second head for his European setup (but has since brought it home). He believes he owns are two of four or five in existence.
The Sparrows’ Sons custom jobber runs into a massive Emperor 6x12 that is loaded with various speakers, but what was mic’d and recorded for the Rundown were a pair of Eminence Texas Heats.
Because he’s Kurt and he’s awesome, not only did he treat this like a recording session, but he used four mics, in four different positions, to show how each works independently and how they work in unison to create a monolithic sledgehammer. The lineup starts (left to right) with an AEA N22 active ribbon mic, Heil Sound PR 30 large diaphragm dynamic supercardioid mic, a Rode (top) Reporter omnidirectional dynamic mic, and an sE Electronics X1 D large diaphragm unidirectional condenser mic.
“One of the nicest things about owning a studio and designing pedals is that I can figure out what do I have a need for,” admits Ballou. And as you’ll soon find out, his biggest (and constant) need is angry, violent, metallic distortion. Starting at the top left (and then going clockwise), we have the Demedash Effects T-120 Videotape Echo. “This is one of the coolest analog delay pedals,” giddily asserts Ballou. He loves the overall functionality of the pedal and its feature set, but the icing on the cake is that when bypassed you can hold down the left footswitch and it will act as a momentary freeze/shimmer/oscillator. Next you have the Shift Line A+ Astronaut III Multiverb Space Unit. Kurt got hip to this pedal when Converge was touring Russia and ventured into a guitar store in St. Petersburg. For this pedal, Kurt’s go-to setting is the reverse shimmer.
The single-knob red GCI design (Oh Yes!) is Kurt’s latest creation (mentions tentatively it may be called Onslaught) that is a “mid-forward, ultimate thrashy, djenty, clanky, articulate, heavy guitar pedal.” The red pedal on the right is Kurt’s first original codesign—the SBD or Super Beatle Distortion—that was inspired by a circuit from Fu Manchu bassist Brad Davis’ Creepy Little Fingers. Taking it up a notch, Ballou added in an active mid boost in front of the fuzz circuit. Additionally, he boosts the bass level after the fuzz circuit so it sounds huge.
Next up in green is the God City Instruments OGR (a collaboration with Electronic Audio Experiments’ John Snyder). The Optical Gain Reduction is a compressor that Ballou uses on every bass-recorded track in God City Studio.
Then there is the Foxrox Electronics Octron2 (inspired by the guitar feedback lassoed by Mahogany Rush guitarist Frank Marino) that Ballou uses for thorny solos that bristle with weird overtones and elastic ghost notes. Following that is a newer GCI Crimson Cock (original codesigned with Rob Davis) that is a treble booster loosely based on the Rangemaster circuit with an added range control (a cap blend on the input) and the switch toggles in a Muff stage at the end of the circuit.
The penultimate stomp is the God City Instruments Ape Eye (collaborated with Soursound) that is dirt box centered around the API 2520 discrete op amp. Lastly, we have Kurt’s Jugendstil silicon fuzz that is aptly described on their site: “If there were a Venn Diagram showing the overlap between ‘90s British shoegaze and ‘90s Swedish death metal, Jugendstil would feel right at home in the middle.” And everything was powered by a Truetone 1 Spot PRO CS7.
An unheralded but appreciated tool used by Ballou is this Radial Engineering SGI TX that is line driver system that takes an unbalanced instrument signal and allows you to drive it as far as 300' feet without noise.
