After a devastating theft in 2021, the metal band’s guitarist rebuilt his tone empire around some life-changing loans.
Chicago post-metal band Russian Circles had to battle their way back to gear heaven. In 2021, the bulk of the band’s gear was stolen while on tour, leading to a years-long rebuild. As a result, many of the items you might’ve seen in guitarist Mike Sullivan’s Rig Rundown back in 2017 are long gone.
PG’s Chris Kies recently met up with Sullivan at the band’s Chicago practice space, where they’ve resided for nearly 20 years. Check out some highlights from Sullivan’s new, resurrected rig below.
Sullivan has been favoring Dunable guitars of late, borrowing one from tourmate Chelsea Wolfe after his other guitar was nabbed. The green one is based on the Dunable Narwhal, with a more Gibson-like scale—comparable to Sullivan’s old Les Paul. This Narwhal has a mahogany body and neck, maple top, and a coil-tap function for the two humbuckers: a DiMarzio PAF 26th Anniversary and a DiMarzio Joe Duplantier Fortitude signature. Vibrating atop those pickups are D’Addario strings—a set of .011–.056, with the low E swapped for a .058. Sullivan uses a number of different down tunings, all with D-A-D-G-A-D as a starting point.
The white Dunable has a maple neck, a 25.5” scale, and is tuned lower, with a .062 for the low E string. It’s used for drop-A tunings, and has the same DiMarzio pickups.
Gettin’ Hi
Sullivan was turned onto Hiwatts after acquiring some on loan in the wake of the gear theft, and he hasn’t turned back since. The cabinets are loaded with Hiwatt Octapulse speakers.
Mike Sullivan’s Pedalboard
Sullivan runs two pedalboards. The first includes a Peterson tuner, Shure P9HW, Dunlop CBM95 Cry Baby Mini, DigiTech Drop and Whammy Ricochet, and MXR Phase 95.
The motherboard carries a Dunlop DVP3 volume pedal, a Friedman BE-OD Deluxe, Strymon Dig, TimeLine, and Flint, a T-Rex Image Looper, DigiTech JamMan Stereo, MXR CAE Boost/Line Driver, Foxrox Octron3, Electric Eye Cannibal Unicorn, Maxon Apex808, Fortin-Modded Ibanez Tube Screamer, and a Radial Shotgun Guitar Splitter and Buffer.
An all-analog flange and chorus with a lot of character.
Way back in the 2010s, before starting Mr. Black as his pedal-building outlet, when Jack DeVille was releasing effects under his own name, he created the Mod Zero. This multi-modulation unit covered flanging, chorus, rotary effects, and vibrato, and, with a limited run of 250 units, gained a reputation and is long sold out.
Although Mr. Black’s Mod.One is not that pedal, this all-original unit designed by DeVille follows a similar mission, and its reverential name is surely no accident. The Mod.One is a 100-percent-analog modulator that spans chorus, flange, and high-band flange with a unique control set designed for flexibility, sonic excitement, options and a lot of character.
Controls for the Curious
If you come to the Mod.One a little fuzzy on the differences between chorus and flange, here’s a brief explanation: Chorus is created using a slower set of delay times on a secondary, parallel signal. Flange uses shorter delay times, and high-band flange the shortest. On the Mod.One, a pair of knobs—one for lower limit and one for upper limit—allow users to set that range of delay times. The lower limit knob has a max delay of 31 mS and a minimum delay of 1.9 ms. The upper limit knob ranges from 1.9 ms to .5 ms. Within those ranges, you’ll find the difference between chorus and flanging, and the position of the two knobs, rather than a switch, determines which effect you’re using. Ultimately, I’m a firm believer that we should use our ears and not get hung up on definitions when listening to an effect. The Mod.One is a great example. Determining exact delay times and whether you’re chorusing or flanging is inexact but ultimately it doesn’t matter. What matters is what sounds good.
The lower limit/upper limit controls might frustrate purists that want to toggle between a clearly defined chorus and flange tone. But Mod.One’s controls, and its central premise, are all about sound sculpting and opening up creative options. And options abound: LFO speed, for example, reaches up to 20 seconds long when using the tap-tempo switch. Six waveform options also widen the sonic lane.
Let’s Get Exponential
The Mod.One is powerful in a literal sense. The active volume control provides plenty of juice, and is capable of really pushing whatever comes next in your chain. That lends a gooey vibe to everything that passes through the pedal. Whether you use that power to drive your amp or not, the combo of gain and all-analog circuitry give the Mod.One a warm, thick voice. This is not just another metallic-sounding flange device.
I found myself stomping on the Mod.One to add space and texture to rhythms, riffs, and leads that cover a lot of range. Sometimes, I was looking for subtlety—Andy Summers on “Walking on the Moon,” for example. For that, I kept the enhance knob, which determines the intensity of the effect, toward lower settings, and kept the speed on the slowest part of its range, which generates molasses-like movement. For more obvious results, I nudged the speed and enhance knobs. There’s a lot of play in each control, so it doesn’t take much to get things moving in a different direction. The enhance control can even self-oscillate at the top of its range, where more extreme sounds live.
Each of these controls interacts differently with alternate waveform settings, making the possibilities exponential. If there’s one complaint I have about the Mod.One—and I do think it’s just one—it’s that it’s hard to tell which waveform is selected. When experimenting by ear, that’s not the worst thing, but when searching for specific settings, it can be hard to tell if the single LED lights up in a sine, triangle, or other pattern. Eventually I got better at telling the difference, but I didn’t always nail it.
To get some ’70s pseudo-cosmiche tones for a recording project, I rocked the triangle, sine, and hypertriangle waveforms at varying levels of excess. And all three were useful for thickening up high-fretted chordage rather than just the crystalline kind of flange I tend to associate with Prince. I found true excess with the step wave selected and the enhance cranked to its fullest, and there are many experimental sounds to be heard in these wilder places. With so many variables at play, I know there is a lot to be discovered still, which makes the Mod.One compelling.
The Verdict
The Mod.One is a powerful flange and chorus with a strong, recognizable character and wide range. It’s not a do-it-all kind of modulator meant to compete with digital units. But this all-analog device can deliver texture to your sound at dosages that are easily controlled. The unique sculpting possibilities make it exciting and refreshing, and in my time with the pedal, I was impressed with how much I hadn’t yet discovered. It strikes a difficult balance between a quick learning curve and the kind of depth that’ll keep it in heavy rotation for a long time to come. It simply sounds excellent, too.

In shape and sound, the Chleo Limited Edition is a very different PRS. It is, in part, a product of the vision of Herman Li, who is one half of the virtuoso lead guitar team behind DragonForce. With a total production of just 200 instruments, and a price tag just below $7,000 (and currently fetching upward of $12,500 on Reverb) the original Maryland-built version remains well out of reach for many of Li’s core fans (not to mention some wealthy landowners).
PRS Chleo SE Herman Li Signature Guitar Demo | First Look
Someone apparently heard the clamor for a more accessibly priced version, though. Enter the PRS SE Chleo. It features the same contoured, maple-topped mahogany body, super-thin neck with 20" fretboard radius, and trifecta of Fishman Fluence single- and double-coil pickups as the more expensive version. It even features Li’s preferred “Eclipse Dragon” fret inlays—a major departure from PRS practice.
All this still comes at a cost. While more affordable than the Limited Edition model, the SE Chleo is priced just under $2,000, which isn’t exactly modest. That raised some eyebrows in the guitar community. After all, the excellent PRS SE DGT David Grissom is around $700 new. The sought-after SE Silver Sky is usually around the high $600 mark. Even the SE Mark Holcomb Signature, the SE Mark Tremonti, and the classic SE Custom 24 Floyd are less than a grand.
Given that the SE Chleo’s materials and build-quality seem on par with those less expensive guitars, what exactly tilts this ostensibly metal-centric SE toward the price range of a U.S.-made PRS Silver Sky or Mark Lettieri Signature Fiore?
Dragon's Teeth
SE Chleo is as well-made and designed as any of the SE class, which is to say, it is very well built. But the SE Chleo also boasts a carbon-fiber reinforced bolt-on maple neck and a custom-contoured maple-topped mahogany body, with an artfully scooped lower cutaway offering unfettered access past the neck’s top 24th fret. The super-flat fretboard radius, smooth ebony fingerboard, and jumbo fretwire mean even the biggest hands will find sure purchase while blazing three-notes-per-string runs and sweep-picked arpeggios. The Chleo’s generous 1.75" nut width also suits the flat radius and is ideal for bigger hands and fretting fanned-out Allan Holdsworth chord voicings.
That said, the body—whose narrow upper and lower horns evoke a 1980s Veillette-Citron—can feel small and a bit awkward while sitting or standing. Whether or not you find the guitar’s ergonomic design beneficial is very personal and subjective, but the SE Chleo’s limited upper-bout surface will offer less support for some players' forearms beyond the wrist. Given that the included steel-saddled Floyd Rose 1000 Tremolo Bridge (with PRS locking nut) practically demands a default palm-mute posture for the right hand, the smaller dimensions sometimes feel like an odd design choice. Herman Li might disagree, however. Weight, by the way, is about 7 pounds, 4 ounces, around the same as an SE Silver Sky.
How to Train Your Dragon
For my money, the most compelling thing about the SE Chleo, and something it shares with its much pricier Limited Edition confrere, is the HSH-arrayed trio of Herman Li Signature Fishman Omniforce hum-free pickups. And with the push-pull volume and tone knobs and 5-way pickup selector blade switch you end up spoiled for choice when it comes to tone blends. Two voicings are available for each pickup using the push-pull tone pot alone. But the push-pull volume pot opens up coil-tap options for each humbucker which can be paired with the middle single-coil pickup. You can also jump the middle pickup entirely and blend the bridge and neck humbucker.
The Chleo’s generous 1.75 nut width suits the flat radius and is ideal for bigger hands and fretting fanned-out Allan Holdsworth chord voicings.
The sound of these single- and double-coil pickup configurations, in concert with the Chleo’s unique body resonance, mean few settings are evocative of a classic Stratocaster, Telecaster, Les Paul, or SG in a literal sense. They can be impeccably clean and have presence, but they are clearly meant to complement the kind of technical, progressive metal that DragonForce excels at with, perhaps, a tip of the cap to PRS-based riff and lead sounds from bands like Opeth, Periphery, and Sevendust.
That said, the bridge pickup’s voicing is aggressive and tight, great for fifth- and sixth-string-based pedal-tone riffing. It also kicks up syrupy sustain for soaring metal lead work (Bleed From Within’s Craig Gowans and Sam Vellen of Caligula’s Horse come to mind). Many other pickup blends hint at the coppery-clean semi-acoustic sounds you associate with King Crimson’s Beat period or latter-day Porcupine Tree.
The Verdict
So, does the PRS SE Chleo merit its nearly $2,000 price tag? Whether it does or doesn’t will be a judgement best left to the beholder. DragonForce’s best-selling record, Inhuman Rampage, moved more than 600,000 copies in the U.S. alone, a prodigious figure for a band and genre outside the mainstream. But that number suggests a lot of possible customers for the SE Chleo, with all its idiosyncracies, as well.
Factor in the persona of Li himself, an affable gentleman rocker and role model who performs challenging technical passages with ease, and the appeal grows. The SE Chleo’s build quality is excellent, so if the guitar design suits your style you should round the “build/design” score up. Similarly, players that favor the Fishman Fluence pickups’ precision should adjust upward accordingly. If Li’s sensational sweep-picking salvos and DragonForce’s fantasy concept albums are your cup of mead, this is a solidbody worth experiencing.

Though the business of cloning pedals is competitive (and endless fodder for frothing Reddit denizens), I appreciate when a pedal company offers a useful twist on an established formula.Warm Audio accomplishes this with the Throne of Tone. It is clearly inspired by theAnalog Man King of Tone. But it is also very obviously a nod to the Marshall Bluesbreaker, the pedal that Mike Piera used as a departure point for his KOT design. The Throne of Tone, though, might mark the point at which the snake bites its tail. It cross-pollinates the circuits in a dual overdrive that opens up many, many tone-coloring avenues and options.
Split Personality
Mike Piera ripped up a friend’s Bluesbreaker to build the first King of Tone. But by the time he rewired it, it was a different pedal altogether. To the extent that the KOT and Bluesbreaker sections are accurate in the Throne of Tone, the differences between the original Bluesbreaker and King of Tone are easy to hear. It’s hard to accurately assess the accuracy of the Throne of Tone’s two circuits without a real-deal King of Tone or Bluesbreaker at hand. But I’ve played through both as well as excellent clones, and in both sound and feel, both Throne of Tone circuits are in the ballpark and better.
In very general terms, that means the “king” side is a bit less aggressive, darker, and more dynamically responsive to changes in pick intensity—especially when you want to go from gnarly to truly clean. The “blues” side is a bit more dynamite, revved up, and lively in the midrange. It’s more immediate and a bit harder to keep on a leash for dynamic purposes. But the Throne of Tone is a great multiplier—and mixer—of these qualities, because you can experience each basic voice through the lens of high gain and low gain settings, a boost, an overdrive or a distortion. Additionally, output from each side can be modified with a presence control which appears on neither pedal in its original form. Add up the possible tone permutations and, well, you’ll probably be less occupied with the accuracy of the circuits, and more excited about harnessing the copious killer tones here.
Pick A Door
Of the three modes, the boost is the most user friendly and easy to apply to a base tone that just needs heft and body. It’s also great for demonstrating the basic duality in the king and blues voices—which align along a Marshall/Fender divide. The blues, or Marshall-like side feels considerably more compressed as a boost, but it positively rings in the high-mid zone. If you want a guitar to be boss in a mix it dishes the goods. But it’s agreeable too, and flattered PAFs, Telecaster single-coils, Wide-Range humbuckers, and a Rickenbacker 12-string—lending all of them an infectious, excited edge. Matched with an EL84 amp it can feel a touch redundant, but with 6L6 amps it shines. The king, or more Fendery side, sounds comparatively scooped. It feels much less hyperactive, and it excels in the clean, low-gain range, but it also gets squishy when you dig in.
These same qualities are very apparent in the overdrive mode. Each voice sounds more compressed than the boost mode. But the higher reaches of the gain controls yield treasure. Here again, the blues side was explosive—sounding at many settings like Malcolm and Angus Young after consuming a bag of firecrackers. Angry but fun. The king’s OD side, at high gain range, sounds much more like a mid- to late-’60s Bassman at high volume: crunchy, but softer around the edges. Each of these voices can be nudged into more savage extremes by the high-gain toggle, which depending on your amp and guitar, can be surprisingly airy to downright sizzly.
The distortion mode kicks the high-midrange in the pants, but retains much of the overdrive mode’s basic coloration. It’s an especially cool match for 6L6 amps—especially on the king side. But the way the distortion modes remain responsive to dynamic input like volume and touch variation is impressive. Distortions can often sound quite binary—either raging or gobbling up midrange oxygen. Both distortions in the Throne of Tone give you gray area to work with that can range down to chiming clean tones.
The Verdict
The original King of Tone and Bluesbreaker pedals are revered for good reason. And if Warm Audio’s take on the two circuits represents even 80 percent of those pedals’ prime tonality, you’ll still hear and feel what makes them special. As a whole, the Throne of Tone is adaptive and versatile. The kind of pedal that could save your hide and solve problems in a studio. But it could work the same magic in a live situation, especially one with a backline surprise in store. In performance, the vertically oriented mini toggles, which are situated perilously close to the bypass switches, could be a liability. I accidentally switched the gain and mode switches with my toe more than once. That’s a shame, because they make experimentation so much easier than when DIP switches are in the mix. It’s hardly a dealbreaker, though. For $229, the Throne of Tone offers a very big bucketful of tone options that can span civilized and rabid.
