We get the scoop on the gear behind Mick Thomson’s and Jim Root’s brutal sound thanks to their signature guitars and 100-watt rock-boxes.
In Cedar Rapids, Iowa, on Mother’s Day 2015, Slipknot guitarists Mick Thomson and Jim Root took some time before their somewhat hometown show and hung with PG to talk about signature guitars, tube heads, and the handful off effects they need to punish arenas each night.
Mick Thomson is a creature of habit—give him a few of his Ibanez MTM signature guitars packed with his Seymour Duncan EMTY Blackout pickups and he’s a happy dude. Each one of his guitars features a mahogany body, maple neck, and rosewood fretboard.
As far as he’s concerned, the best guitar he has out on the road right now is his white-and-black “storm trooper” Ibanez MTM that’s kept tuned to dropped-B. According to Thomson, it’s perfect for rhythm work and can stand up against any other 6-string in his collection for leads. Nearly all of 2008’s All Hope is Gone and the bulk of the rhythm material for last year’s .5: The Gray Chapter was done with the storm trooper. For this run, the band is primarily using two tunings and he uses a different set of D’Addario EXL117 strings for each one. For dropped-A tunings, he goes with .011–.058 and for dropped-B tunings he goes with .012–.068. Thomson recently worked with Dunlop to create a custom Jazz III pick made of a graphite composite because he feels they’re slicker, harder, and doesn’t make any scraping or scratching sounds when they wear down.
This is #7’s backup to the storm trooper—his very first prototype he got for his signature line back in the early 2000s.
Thomson starts the night out with this Oakland Raiders-themed Ibanez MTM that’s tuned to dropped-A for “Sacrastrophe.”
Thomson’s newest signature model features a carbon-fiber cap on the body and headstock and is tuned to dropped-A.
All of Thomson’s Audio-Technica wireless packs on his guitars are protected by Trojan condoms to keep them from getting wet from water, beer, sweat, and blood.
Much like his guitars, Mick rocks only the gear with his name on it—for this tour, he’s been using two Rivera KR-7 heads. One head goes to front of house and the second head runs through a 1x12 iso cabinet with a Celestion G-12K-100 because it meshes well with the third channel of the KR-7 and allows more headroom giving more clarity to the drop-tuned notes.
The secret weapon of his amp setup is the Rivera RockCrusher because he runs the FOH signal through the unit allowing him and his tech to color and dial in the sound from room to room or venue to venue. In addition, the RockCrusher can emulate most speakers on the market making it an invaluable tool for Mick in the studio.
Thomson’s rack of effects is slim—but utilitarian. He only uses six effects plus a Voodoo Lab Pedal Power ISO-5 and Peterson Stomp Classic tuner. His noisemakers include a Maxon OD-820 Overdrive Pro for lead boosts, an Electro-Harmonix Bassballs that’s kicked on for “Disasterpiece,” an MXR Carbon Copy Delay for parts of “Vermillion,” a Death By Audio Fuzz War, and a custom-made octave fuzz created by Thomson’s tech Kevin Allen. Mick commissioned his tech to make the filthiest, gnarliest, most obnoxious-sounding fuzzbox possible because as the guitarist sees it, “the fuzz better fuck your sound up.” He uses the custom octave fuzz on parts of “Duality.”
His rackmounted gear includes Audio-Technica wireless units, a Furman power conditioner, a Boss GT-Pro, and a Dunlop Custom Shop DCR-2SR Cry Baby Rack Wah. Thomson uses the GT-Pro to mimic the vocal sounds he originally recorded on tracks like “Spit It Out,” “Surfacing,” “Prosthetics,” and others off their 1999 self-titled debut. He switched to the GT-Pro from the Boss GX-700 during the recording of All Hope is Gone because of the updated algorithms, added MIDI capabilities, and to preserve the 700’s life.
Tech Kevin Allen uses a Voodoo Lab Ground Control Pro backstage to do all of Thomson’s switching throughout a show.
Like his 6-string counterpart, Jim Root uses various body stylings of his signature Fender guitars that feature mahogany bodies, maple necks, rosewood fretboards—ebony for his Jazzmasters—single volume knob, and EMG pickups. All of his axes are equipped with Dunlop .011–.056 strings for dropped-A and .012–.058 for dropped-B tunings. And for guitar picks, #4 recently collaborated with Dunlop to customize a Jazz III nylon pick that is the shape of a Tortex III pick.
His newest signature guitar is a sandblasted Jazzmaster that he recently created with Fender. The company describes the process as “leaving the surface grain pattern wonderfully textured with parallel ruts and grooves in which the black grain-filler coat shows beneath the color finish coat.” Root commented that he feels the removal of some of the wood makes this particular Jazzmaster more resonant. This sig offset has an EMG 81 in the bridge and a 60 in the neck.
This signature model Jazzmaster is a flat-black model that is loaded with the EMG JH Het Set pickups that Root feels has more headroom and offers a more “rounder” saturation than the standard 81-60 pairing.
Jim’s favorite stage guitar has been his first signature Tele that was conceptualized with Fender in the early 2000s. The dual-humbucker, mahogany-bodied Telecaster has been used on every album and every tour since he received it nearly 10 years ago. Root hopes to convince Fender to do a limited run of relic’d copies of this guitar in the future.
His lone signature Strat has a matte silver finish with a patina copper pickguard. He currently uses this one the least because it is extra bright.
While he does a have a signature Orange head—#4 Jim Root Terror—he’s currently using a pair of Rockerverbs for his live sound. His main live amp is a Rockerverb 100 that runs into an isolated Orange 4x12 cab loaded with Celestion Vintage 30s that is close-mic’d with three Audio-Technica AT4050s.
His backup head is a Rockerverb 100 MKII.
Root’s batch of effects are fairly simple and straightforward as he has an old Boss NS-2 Noise Suppressor—he claims the updated circuitry and lead-free solder in the new versions are less desirable and impact his sound too much—an MXR Auto Q Wah, a Maxon AF-9 Auto Filter, a Maxon PT-9 Pro+ Phase Shifter, two MXR Carbon Copy Delays—each is set with varying decay and repeat lengths—an Electro-Harmonix Holy Grail Reverb, and an Electro-Harmonix Micro POG. A T-Rex FuelTank Classic powers his stomps.
His satellite board that sits out front onstage includes a Cry Baby controller for the rack-mounted wah, a third MXR Carbon Copy so he can create oscillating chaos, a Maxon FV10 Fuzz Elements Void, an MXR GT-OD for a backup dirt box, and a Dunlop JH1D Jimi Hendrix Signature Wah. He feels the Hendrix wah has a different vibe that is a bit more traditional sounding effect that harkens back to the earliest Vox models. The Hendrix wah sits on a G-Lab True Bypass Wah-Pad that allows Root to leave the wah half-cocked without having to ride the foot pedal.

How David Gilmour masterully employs target notes to make his solos sing.
When I was an undergraduate jazz performance major struggling to get a handle on bebop improvisation, I remember my professor Dave LaLama admonishing me, “If you think playing over the fast tunes is hard, wait until you try playing over the ballads. What Dr. Lalama was trying to impart was that playing fast scales over fast changes could get you by, but playing melodically over slow tempos, when your note choices are much more exposed, would really test how well you could create meaningful phrases.
Although getting past the “this scale works over these chords” approach to improvisation generally requires hours of shedding, aiming for particular target notes (specific notes over specific chords) is an optimum strategy to maximize your practice time. In the realm of rock guitar, I can think of no greater master of the melodic target note technique while playing ballads than David Gilmour.
For the unfamiliar few, Gilmour was first enlisted by fledgling psychedelic rockers Pink Floyd in 1967, when original guitarist/vocalist Syd Barrett began having drug-induced struggles with mental health. The band experimented with various artistic approaches for several years before refining them into a cohesive “art rock” sound by the early ’70s. The result was an unbroken streak of classic, genre-defining conceptual albums that included Meddle, The Dark Side of the Moon, Wish You Were Here, Animals, and The Wall. Although bassist/vocalist Roger Waters assumed the role of de facto bandleader and primary songwriter, Gilmour was a significant contributor who was praised for his soulful singing and expertly phrased lead playing that seemed to magically rework pedestrian blues phrases into sublimely evocative melodies. His focus on musicality over excessive displays of technique made him a musician’s musician of sorts and earned him a stellar reputation in guitar circles. When Roger Waters left Pink Floyd in the mid ’80s, Gilmour surprised many by calmly assuming the leadership mantle, leading the band through another decade of chart-topping albums and stadium tours. Although Pink Floyd are not officially broken up (keyboardist and founding member Richard Wright died in 2008 while Gilmour and drummer Nick Mason joined forces with Ukrainian singer Andriy Khlyvnyuk on the one-off single “Hey Hey Rise Up” in 2022), Gilmour has mostly spent the last few decades concentrating on his solo career. His latest release, Luck and Strange, features his wife, novelist Polly Sampson, as primary lyricist and daughter Romany Gilmour as vocalist on several tracks. His recent tour filled arenas around the world.
Let’s take a page from Gilmour’s hallowed playbook and see how incorporating a few well-chosen target notes can give our playing more melody and structure.
For the sake of simplicity, all the examples use the Gm/Bb major pentatonic scale forms. In my experience as a teacher, I find that most students can get a pretty solid handle on the root-position, Form-I minor pentatonic scale but struggle to incorporate the other four shapes while playing lead. One suggestion I give them is to work on playing the scales from the top notes down and focus on the four highest strings only. I believe this is a more logical and useful approach to incorporating these forms into your vocabulary. Try playing through Ex. 1, Ex. 2, Ex. 3, and Ex. 4, which are based on the top-down approach of the Form I, Form II, Form IV, and Form I (up an octave) shapes respectively.
Ex. 1
Ex. 2
Ex. 3
Ex. 4
Once you’ve gotten a handle on the scales, try playing Ex. 5, which is loosely based on the extended introduction to Pink Floyd’s “Shine On You Crazy Diamond.” We begin by soloing over a static Gm chord for four measures. As target notes, I’ve chosen the root and 5th of the G minor chord ( the notes G and D, respectively). In the first measure, we’re starting in a minor pentatonic Form I with a bend up to the root of the Gm chord. A flurry of notes on beat 4 sets us up for the bend to the D in the second measure. The D note is again targeted in measure three—this time up an octave via a shift into the minor pentatonic Form II shape. Measure four aims for the G tonic up an octave, but ends with a bend that targets a C—the root of the IVm (Cm) chord in the final measure. By focusing on target notes and connecting them with embellishing licks, your lead lines will have a much better sense of direction and melodic narrative. Also, by only targeting the root and 5th of the chord, the target note approach will be easily transferrable to songs in a G blues context (G pentatonic minor over a G major or G dominant tonality).
Ex. 5
A further exploration of this approach, Ex. 6 begins with a two-beat pickup that resolves to the scale tonic G. This time however, the G isn’t serving as the root of the Im chord. Instead, it’s the 5th of Cm—the IVm chord. Employing the root of the pentatonic scale as the fifth of the IVm chord is a textbook Gilmour-ism and you can hear him use it to good effect on the extended intro to “Echoes” from Live in Gdansk. When approaching the C on beat 2 of the second full measure, bend up from the Bb on the 6th fret of the 1st string then slide up to the C on the 8th fret without releasing the bend or picking again. In the final measure, I’ve introduced two Db notes, which serve as the b5 “blue note” of the scale and provide melodically compelling passing tones on the way to the G target note on beat 4.
Ex. 6
Exclusively positioned in the Form-IV G minor pentatonic shape, Ex. 7 is based on a bluesy lick over the I chord in the first and third measures that alternately targets a resolution to the root of the IV chord (C ) and the root of the V chord (D7#9) in the second and fourth measures. Being able to resolve your lead phrases to the roots of the I, IV, and V chords on the fly is an essential skill ace improvisers like Gilmour have mastered.
Ex. 7
Now let’s turn our attention to the Bb major pentatonic scale, which is the relative major of G minor. Play through the Form I and Form II shapes detailed in Ex. 8 and Ex. 9 below. You’ll see I’ve added an Eb to the scale (technically making them hexatonic scales). This allows us a bit more melodic freedom and—most importantly—gives us the root note of the IV chord.
Ex. 8
Ex. 9
Channeling the melodic mojo of Gilmour’s lead jaunts on Pink Floyd’s “Mother” and “Comfortably Numb,” Ex. 10 targets chord tones from the I, IV, and V (Bb, Eb, and F) chords.
The muted-string rake in first measure helps “sting” the F note, which is the 5th of the Bb. Measure two targets a G note which is the 3rd of the Eb. This same chord/target note pairing is repeated in the third and fourth measures, although the G is now down an octave. For the F and Eb chords of measures five and six, I’ve mirrored a favorite Gilmour go-to: bending up to the 3rd of a chord then releasing and resolving to the root (an A resolving to an F for the F chord and a G resolving to an Eb for the Eb chord.) The final measure follows a melodic run down the Bb scale that ultimately resolves on the tonic. Be sure to pay attention to the intonation of all your bends, especially the half-step bend on the first beat of measure seven.
As a takeaway from this lesson, let’s strive to “Be Like Dave” and pay closer attention to target notes when soloing. Identify the roots of all the chords you’re playing over in your scales and aim for them as the beginning and/or ending notes of your phrases. Think of these target notes as support beams that will provide structure to your lead lines and ultimately make them more melodically compelling.

MT 15 and Archon 50 Classic amplifiers offer fresh tones in release alongside a doubled-in-size Archon cabinet
PRS Guitars today released the updated MT 15 and the new Archon Classic amplifiers, along with a larger Archon speaker cabinet. The 15-watt, two-channel Mark Tremonti signature amp MT 15 now features a lead channel overdrive control. An addition to the Archon series, not a replacement, the 50-watt Classic offers a fresh voice by producing retro rock “classic” tones reminiscent of sound permeating the radio four and five decades ago. Now twice the size of the first Archon cabinet, the Archon 4x12 boasts four Celestion V-Type speakers.
MT 15 Amplifier Head
Balancing aggression and articulation, this 15-watt amp supplies both heavy rhythms and clear lead tones. The MT 15 revision builds off the design of the MT 100, bringing the voice of the 100’s overdrive channel into its smaller-format sibling. Updating the model, the lead channel also features a push/pull overdrive control that removes two gain stages to produce vintage, crunchier “mid gain” tones. The clean channel still features a push/pull boost control that adds a touch of overdrive crunch. A half-power switch takes the MT to 7 watts.
“Seven years ago, we released my signature MT 15 amplifier, a compact powerhouse that quickly became a go-to for players seeking both pristine cleans and crushing high-gain tones. In 2023, we took things even further with the MT 100, delivering a full-scale amplifier that carried my signature sound to the next level. That inspired us to find a way to fit the 100's third channel into the 15's lunchbox size,” said Mark Tremonti.
“Today, I’m beyond excited to introduce the next evolution of the MT15, now featuring a push/pull overdrive control on the Lead channel and a half-power switch, giving players even more tonal flexibility to shape their sound with a compact amp. Can’t wait for you all to plug in and experience it!”
Archon Classic Amplifier Head
With a refined gain structure from the original Archon, the Archon Classic’s lead channel offers a wider range of tones colored with gain, especially in the midrange. The clean channel goes from pristine all the way to the edge of breakup. This additional Archon version was developed to be a go-to tool for playing classic rock or pushing the envelope into modern territory. The Archon Classic still features the original’s bright switch, presence and depth controls. PRS continues to stock the Archon in retailers worldwide.
“The Archon Classic is not a re-issue of the original Archon, but a newly voiced circuit with the lead channel excelling in '70s and '80s rock tones and a hotter clean channel able to go into breakup. This is the answer for those wanting an Archon with a hotrod vintage lead channel gain structure without changing preamp tube types, and a juiced- up clean channel without having to use a boost pedal, all wrapped up in a retro-inspired cabinet design,” said PRS Amp Designer Doug Sewell.
Archon 4x12 Cabinet
As in the Archon 1x12 and 2x12, the mega-sized PRS Archon 4x12 speaker cabinet features Celestion V-Type speakers and a closed-back design, delivering power, punch, and tight low end. Also like its smaller brethren, the 4x12 is wrapped in durable black vinyl and adorned with a British-style black knitted-weave grill cloth. The Archon 4x12 is only the second four-speaker cabinet in the PRS lineup, next to the HDRX 4x12.
