Converge’s 6-string steamroller—who also happens to be a famously heavy and in-demand producer (and gear designer)—takes PG inside his GodCity Studio to talk mics, tracking, instrument building, and more.
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.)
A close-up of his Malcolm Young-inspired Craftsman Series 1 body.
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.

This legendary vintage rack unit will inspire you to think about effects with a new perspective.
When guitarists think of effects, we usually jump straight to stompboxes—they’re part of the culture! And besides, footswitches have real benefits when your hands are otherwise occupied. But real-time toggling isn’t always important. In the recording studio, where we’re often crafting sounds for each section of a song individually, there’s little reason to avoid rack gear and its possibilities. Enter the iconic Eventide H3000 (and its massive creative potential).
When it debuted in 1987, the H3000 was marketed as an “intelligent pitch-changer” that could generate stereo harmonies in a user-specified key. This was heady stuff in the ’80s! But while diatonic harmonizing grabbed the headlines, subtler uses of this pitch-shifter cemented its legacy. Patch 231 MICROPITCHSHIFT, for example, is a big reason the H3000 persists in racks everywhere. It’s essentially a pair of very short, single-repeat delays: The left side is pitched slightly up while the right side is pitched slightly down (default is ±9 cents). The resulting tripling/thickening effect has long been a mix-engineer staple for pop vocals, and it’s also my first call when I want a stereo chorus for guitar.
The second-gen H3000S, introduced the following year, cemented the device’s guitar bona fides. Early-adopter Steve Vai was such a proponent of the first edition that Eventide asked him to contribute 48 signature sounds for the new model (patches 700-747). Still-later revisions like the H3000B and H3000D/SE added even more functionality, but these days it’s not too important which model you have. Comprehensive EPROM chips containing every patch from all generations of H3000 (plus the later H3500) are readily available for a modest cost, and are a fairly straightforward install.
In addition to pitch-shifting, there are excellent modulation effects and reverbs (like patch 211 CANYON), plus presets inspired by other classic Eventide boxes, like the patch 513 INSTANT PHASER. A comprehensive accounting of the H3000’s capabilities would be tedious, but suffice to say that even the stock presets get deliciously far afield. There are pitch-shifting reverbs that sound like fever-dream ancestors of Strymon’s “shimmer” effect. There are backwards-guitar simulators, multiple extraterrestrial voices, peculiar foreshadows of the EarthQuaker Devices Arpanoid and Rainbow Machine (check out patch 208 BIZARRMONIZER), and even button-triggered Foley effects that require no input signal (including a siren, helicopter, tank, submarine, ocean waves, thunder, and wind). If you’re ever without your deck of Oblique Strategies cards, the H3000’s singular knob makes a pretty good substitute. (Spin the big wheel and find out what you’ve won!)
“If you’re ever without your deck of Oblique Strategies cards, the H3000’s singular knob makes a pretty good substitute.”
But there’s another, more pedestrian reason I tend to reach for the H3000 and its rackmount relatives in the studio: I like to do certain types of processing after the mic. It’s easy to overlook, but guitar speakers are signal processors in their own right. They roll off high and low end, they distort when pushed, and the cabinets in which they’re mounted introduce resonances. While this type of de facto processing often flatters the guitar itself, it isn’t always advantageous for effects.
Effects loops allow time-based effects to be placed after preamp distortion, but I like to go one further. By miking the amp first and then sending signal to effects in parallel, I can get full bandwidth from the airy reverbs and radical pitched-up effects the H3000 can offer—and I can get it in stereo, printed to its own track, allowing the wet/dry balance to be revisited later, if needed. If a sound needs to be reproduced live, that’s a problem for later. (Something evocative enough can usually be extracted from a pedal-form descendant like the Eventide H90.)
Like most vintage gear, the H3000 has some endearing quirks. Even as it knowingly preserves glitches from earlier Eventide harmonizers (patch 217 DUAL H910s), it betrays its age with a few idiosyncrasies of its own. Extreme pitch-shifting exhibits a lot of aliasing (think: bit-crusher sounds), and the analog Murata filter modules impart a hint of warmth that many plug-in versions don’t quite capture. (They also have a habit of leaking black goo all over the motherboard!) It’s all part of the charm of the unit, beloved by its adherents. (Well, maybe not the leaking goo!)
In 2025, many guitarists won’t be eager to care for what is essentially an expensive, cranky, decades-old computer. Even the excitement of occasional tantalum capacitor explosions is unlikely to win them over! Fortunately, some great software emulations exist—Eventide’s own plugin even models the behavior of the Murata filters. But hardware offers the full hands-on experience, so next time you spot an old H3000 in a rack somewhere—and you’ve got the time—fire it up, wait for the distinctive “click” of its relays, spin the knob, and start digging.

The luthier’s stash.
There is more to a guitar than just the details.
A guitar is not simply a collection of wood, wire, and metal—it is an act of faith. Faith that a slab of lumber can be coaxed to sing, and that magnets and copper wire can capture something as expansive as human emotion. While it’s comforting to think that tone can be calculated like a tax return, the truth is far messier. A guitar is a living argument between its components—an uneasy alliance of materials and craftsmanship. When it works, it’s glorious.
The Uncooperative Nature of Wood
For me it all starts with the wood. Not just the species, but the piece. Despite what spec sheets and tonewood debates would have you believe, no two boards are the same. One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.
Builders know this, which is why you’ll occasionally catch one tapping on a rough blank, head cocked like a bird listening. They’re not crazy. They’re hunting for a lively, responsive quality that makes the wood feel awake in your hands. But wood is less than half the battle. So many guitarists make the mistake of buying the lumber instead of the luthier.
Pickups: Magnetic Hopes and Dreams
The engine of the guitar, pickups are the part that allegedly defines the electric guitar’s voice. Sure, swapping pickups will alter the tonality, to use a color metaphor, but they can only translate what’s already there, and there’s little percentage in trying to wake the dead. Yet, pickups do matter. A PAF-style might offer more harmonic complexity, or an overwound single-coil may bring some extra snarl, but here’s the thing: Two pickups made to the same specs can still sound different. The wire tension, the winding pattern, or even the temperature on the assembly line that day all add tiny variables that the spec sheet doesn’t mention. Don’t even get me started about the unrepeatability of “hand-scatter winding,” unless you’re a compulsive gambler.
“One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.”
Wires, Caps, and Wishful Thinking
Inside the control cavity, the pots and capacitors await, quietly shaping your tone whether you notice them or not. A potentiometer swap can make your volume taper feel like an on/off switch or smooth as an aged Tennessee whiskey. A capacitor change can make or break the tone control’s usefulness. It’s subtle, but noticeable. The kind of detail that sends people down the rabbit hole of swapping $3 capacitors for $50 “vintage-spec” caps, just to see if they can “feel” the mojo of the 1950s.
Hardware: The Unsung Saboteur
Bridges, nuts, tuners, and tailpieces are occasionally credited for their sonic contributions, but they’re quietly running the show. A steel block reflects and resonates differently than a die-cast zinc or aluminum bridge. Sloppy threads on bridge studs can weigh in, just as plate-style bridges can couple firmly to the body. Tuning machines can influence not just tuning stability, but their weight can alter the way the headstock itself vibrates.
It’s All Connected
Then there’s the neck joint—the place where sustain goes to die. A tight neck pocket allows the energy to transfer efficiently. A sloppy fit? Some credit it for creating the infamous cluck and twang of Fender guitars, so pick your poison. One of the most important specs is scale length. A longer scale not only creates more string tension, it also requires the frets to be further apart. This changes the feel and the sound. A shorter scale seems to diminish bright overtones, accentuating the lows and mids. Scale length has a definite effect on where the neck joins the body and the position of the bridge, where compromises must be made in a guitar’s overall design. There are so many choices, and just as many opportunities to miss the mark. It’s like driving without a map unless you’ve been there before.
Alchemy, Not Arithmetic
At the end of the day, a guitar’s greatness doesn’t come from its spec sheet. It’s not about the wood species or the coil-wire gauge. It’s about how it all conspires to either soar or sink. Two guitars, built to identical specs, can feel like long-lost soulmates or total strangers. All of these factors are why mix-and-match mods are a long game that can eventually pay off. But that’s the mystery of it. You can’t build magic from a parts list. You can’t buy mojo by the pound. A guitar is more than the sum of its parts—it’s a sometimes unpredictable collaboration of materials, choices, and human touch. And sometimes, whether in the hands of an experienced builder or a dedicated tinkerer, it just works.
