The recording

Tuning Drop B (B‑F♯‑B‑E‑G♯‑C♯)
Signal chain
Original gear
Ibanez MTM1
Guitar
Mick Thomson’s signature Ibanez MTM1, fitted with Seymour Duncan EMTY Blackout pickups, delivers the tight, percussive rhythm tone on Duality, tuned down to Drop B.
Fender Jim Root Telecaster
Guitar
Jim Root’s signature Telecaster, equipped with EMG 81/60 active pickups, provides the cutting lead and second rhythm voice on Duality, also set to Drop B.
Peavey 5150
Amp
Thomson routed his MTM1 into a Peavey 5150, cranking the gain to near‑full to achieve the aggressive, scooped‑mid distortion heard throughout Duality.
Mesa/Boogie Triple Rectifier
Amp
Root employed a Mesa/Boogie Triple Rectifier to shape the thick, low‑centered rhythm tone that underpins Duality’s heavy riffing.
Alternatives
Practical playing approach
Recreation guidance, not a claim about undocumented studio control positions.
- 1.Tune all guitars to Drop B (B‑F♯‑B‑E‑G♯‑C♯) before playing.
- 2.Use heavy gauge strings (e.g., .012–.056) to keep the low B tight and articulate.
- 3.Apply aggressive palm‑muting on the low strings for the chugging rhythm feel.
- 4.Pick near the bridge with a stiff pick to accentuate attack and clarity.
- 5.Lock the low B string at the nut or use a string tree to prevent fret buzz.

Frequently asked questions
What gear was used for the Duality guitar tone?
The available research points to Ibanez MTM1 into Peavey 5150. The full reported signal chain and evidence links are listed on this page.
Are the original Duality amp settings documented?
Exact historical knob positions are not reliably documented for most recordings. ToneTwin does not publish generated values as studio fact; it creates playable settings only for the amp and pedals a player selects.
What tuning is Duality in?
The current research record lists Drop B (B‑F♯‑B‑E‑G♯‑C♯). ToneTwin keeps corrections open when reliable accounts disagree.
How do I recreate the Duality tone on my own gear?
Use the reported pickup, gain character, effects and signal-chain order as the target, then translate that target to your equipment. The matcher models controls for your selected rig rather than copying undocumented studio numbers.
