James Hetfield's guitar strings: the Metallica rhythm rig, sourced
Documented string gauges, brands, and tunings James Hetfield has used across Metallica's career. With citations.
Metallica · reviewed by the Change Your Strings editorial team ·
James Hetfield has used Ernie Ball Regular Slinky (.010 to .046) for the majority of Metallica's catalog in E standard and Eb standard. In April 2022 Ernie Ball launched the Papa Het's Hardwired Master Core signature set in a new .011 to .050 gauge. For Drop tunings, Hetfield's tech is documented swapping to heavier gauges, with public sources less consistent on the exact spec. He has been an Ernie Ball signature artist for decades.

Who James Hetfield is
James Alan Hetfield, born August 3, 1963, in Downey, California, founded Metallica with Lars Ulrich in 1981. Across 40-plus years, ten studio albums, and the genre-defining run from Kill 'Em All (1983) through 72 Seasons (2023), Hetfield's downpicked right hand and Eb-standard rhythm tone are the foundational vocabulary of thrash metal.
A documented ESP signature artist (Snakebyte, Iron Cross, Vulture, Truckster, MX-220) and Ernie Ball signature artist (Papa Het's Hardwired Master Core launched 2022), Hetfield's rig has been the most-photographed metal-guitar setup of the modern era. Premier Guitar's Metallica Rig Rundowns from 2009, 2017, and 2023 are the canonical primary sources for the gear-by-tour evolution; Guitar World tech interviews and the Metallica documentary catalog (Some Kind of Monster, Mission to Lars) round out the public record.
Inducted into the Rock and Roll Hall of Fame in 2009.
Electric guitars
Current main · ESP signature · 2009-onward
ESP James Hetfield Snakebyte
Mahogany body, set-neck mahogany, ebony fretboard, pearloid block inlays, EMG JH Het Set humbuckers, TonePros locking bridge. Hetfield's primary live and studio guitar from 2009 through the current touring era. Available in black satin and snow white finishes; the production model (LTD) is the most-shipped Hetfield signature in history.
The 1984 Explorer · "More Beer"
Gibson Explorer 1984 (modified)
Hetfield's most-iconic 1980s guitar. White Gibson Explorer with the "MORE BEER!" decal across the body, EMG humbucker swap, used across the Master of Puppets and ...And Justice for All touring eras. Documented in countless 1986-1991 live photographs. Currently retired from active touring; lives in the Metallica vault as a documented relic of the thrash era.
ESP signature · 2010-onward · Iron Cross graphic
ESP James Hetfield Iron Cross
Explorer body shape, mahogany construction, set-neck, ebony fretboard, EMG JH Het Set, signature white-with-iron-cross graphic finish. The Hetfield signature that pulls forward the visual language of his classic Explorers into a modern playing platform. Live rotation in the 2010s WorldWired and 72 Seasons touring eras alongside the Snakebyte.
ESP signature · V-shape · Vulture
ESP James Hetfield Vulture
Flying-V shape signature, mahogany body, set-neck, ebony fretboard with mother-of-pearl block inlays, EMG JH Het Set, TonePros locking bridge. Touring rotation guitar; appears in 72 Seasons era live photography for V-shape moments and as a backup to the Snakebyte for Eb-standard rhythm work.
ESP signature · Telecaster-style · Truckster
ESP James Hetfield Truckster
Single-cut body shape inspired by Telecaster outline, mahogany body, mahogany neck, EMG JH Het Set, distressed military-green finish. The single-cut Hetfield signature that fills the slot the Snakebyte does not, used for the Death Magnetic and World Magnetic touring eras as a primary live guitar before the Snakebyte launched.
1991-2009 era · Black Album to Death Magnetic
ESP MX-220 Eet Fuk Explorer
The black ESP Explorer with the "EET FUK" decal that succeeded the More Beer Gibson as Hetfield's main live guitar from the Black Album touring cycle through Death Magnetic. EMG humbucker, ESP custom-shop build, the visual reference point for an entire generation of Metallica fans. Retired around 2009 when the Truckster and Snakebyte took over the rotation.

Acoustic guitars
Studio acoustic · Hardwired era and prior
Gibson J-200 (and J-200 variants)
The Gibson super-jumbo is Hetfield's documented studio acoustic across the Black Album balladry (Nothing Else Matters, The Unforgiven), S&M orchestral arrangements, and the Hardwired To Self-Destruct catalog. Spruce top, maple back and sides, the canonical big-body strummer. Strings tend toward Ernie Ball Earthwood phosphor bronze in medium gauges (.013-.056) for the percussive attack the songs demand.
Amps
1980s · The Master of Puppets / Justice studio amp
Mesa/Boogie Mark IIC+
The Mark IIC+ Lead channel into a 4x12 cab is widely cited as the studio voice behind Master of Puppets and ...And Justice for All. The IIC+ remains a reference voice in Hetfield's rig in the modern era, including as one of the modeled amps in his current Axe-FX rig.

Long-running primary · Tube-amp era through the 2010s
Mesa/Boogie Triple Rectifier
A Mesa Triple Rectifier was Hetfield's main live amp from the Black Album touring cycle onward. Three-channel 150-watt tube head, a modern-metal high-gain reference. In the current Axe-FX-driven rig, Mesa power amps still feed Hetfield's stage cabinets for monitoring.

Studio voice · Modern era
Diezel VH4
German-made four-channel 100-watt tube head. The Diezel VH4 is one of the documented amps in Hetfield's modern rig, blended with the Mark IIC+ voice for layered rhythm tone. In the current Axe-FX-based live rig, both the Mark IIC+ and Diezel VH4 are used as modeled amps.

Current live rig · Modeled amps direct to FOH
Fractal Audio Axe-FX
Per Hetfield's tech Chad Zaemisch, the modern Metallica live rig runs Hetfield's signal through Axe-FX units (with Mark IIC+ and Diezel VH4 amp models) direct to front of house. Mesa power amps drive on-stage cabinets for monitoring and stage feel; the cabinets are not miked. The transition predates and runs through the 72 Seasons touring cycle.

Effects
Documented overdrive boost
Boss SD-1 Super Overdrive
Documented as part of Hetfield's overdrive lineage. The SD-1's mid-pushed, asymmetric clipping tightens the amp's low end and adds upper-mid bite. Hetfield is well known to be private about his exact pedal settings; specific values cited online are usually fan reverse-engineering rather than published spec.
Modulation · Sparingly used
MXR Phase 90
A phaser is documented in the lineage of Hetfield's effects, used sparingly on specific songs. The MXR Phase 90 is the most-cited single-knob phaser in modern rock and metal.
Wah · Per-song application
Dunlop Cry Baby Wah
A standard Cry Baby wah is documented in Hetfield's pedalboard, used per-song rather than as a constant tone-shaping tool.
Noise gate · For tight high-gain rhythm
ISP Decimator
High-gain rhythm tone with active humbuckers requires a transparent noise gate. The ISP Decimator series is documented in Hetfield's signal chain.
Strings
Documented Ernie Ball artist · E and Eb standard
Ernie Ball Regular Slinky (.010 to .046)
Nickel-plated steel, the working-pro metal-rhythm gauge. Hetfield's documented long-running set in E standard and Eb standard across Metallica's catalog. He has been an Ernie Ball signature artist for decades.
Signature set · Launched April / May 2022
Ernie Ball Papa Het's Hardwired Master Core (.011 to .050)
Hetfield's signature set with Ernie Ball, co-developed for his aggressive picking attack. Released through the Metallica.com store on April 26, 2022 and through Ernie Ball retailers on May 10, 2022. The .011 to .050 gauge is a configuration not previously offered by Ernie Ball.

Picks
Signature pick · Tortex Flow shape · 1.14mm
Dunlop Tortex Flow Hetfield White Fang 1.14mm
Hetfield's documented signature pick. White Tortex material in the Flow shape (rounded triangle with a sharper attack point), 1.14mm gauge for the percussive picking attack his rhythm playing requires. The Flow shape is the post-2010 Hetfield rotation; earlier eras saw Tortex Standard 1.14mm in green-stripe variants.
Endorsed vs. verified use
Hetfield is a documented Ernie Ball, ESP, EMG, Mesa/Boogie, Diezel, and Dunlop endorsed artist. He is also a verified user across all of those categories: Premier Guitar Rig Rundown footage, Metallica documentary footage, and Guitar World tech interviews consistently show the same brands his endorsement deals reference. The endorsement and the actual use align, which is rare in the industry and is part of why his rig is the most-cited reference setup in modern metal guitar.
Why a .010 to .046 gauge for a metal rig
Bedroom metal forums often argue that metal requires .012 sets. Hetfield's career is a counterargument. Nickel-plated steel in a .010 gauge, picked hard into a high-output humbucker (EMG JH Het Set) and a tight gate, has been responsible for some of the most recognizable rhythm tones in rock history. Gauge matters less than picking attack, amp voicing, and gate discipline. His more recent Papa Het's signature set steps up to .011 to .050, but the broader point stands: if a .010 set can hold up in Eb standard for decades across Metallica's catalog, lighter gauges are enough for most of the rest of us.
