The main guitars in Metallica's sound

Metallica's two lead guitarists, Kirk Hammett and James Hetfield, have used different instruments throughout the band's history, but both have settled on guitars built to their specifications by ESP, a Japanese manufacturer. Kirk Hammett plays a signature ESP KH-2 model, while James Hetfield uses an ESP EH custom design. These are not off-the-shelf guitars—they are built to each player's exact requirements for weight, neck profile, pickup configuration, and finish.

The choice of ESP reflects what both guitarists need: instruments that can handle the downtuned, heavy strings Metallica uses and stay in tune during aggressive playing. Metallica typically tunes their guitars a half-step or full-step lower than standard tuning, which puts extra tension on the neck and requires a guitar built to handle that stress without warping or losing intonation.

Key Takeaways

  • Kirk Hammett plays an ESP KH-2 signature model, a guitar designed specifically for his playing style and hand geometry.
  • James Hetfield uses a custom ESP EH model that is built to his specifications rather than a standard production guitar.
  • Both guitarists use downtuned strings and heavy-gauge sets, which requires guitars with reinforced necks and hardware rated for that tension.
  • Metallica's guitar tone comes from a combination of the instrument, amplifiers (typically Marshall stacks), and the playing technique itself.
  • The specific model a Metallica member uses has changed over decades—these are their current primary instruments.

Kirk Hammett's ESP KH-2

Kirk Hammett's signature guitar, the ESP KH-2, is a solid-body electric with a mahogany body and a thin U-shaped neck. The guitar comes with EMG pickups, which are active pickups that require a battery and produce a high-output signal ideal for heavy distortion. The KH-2 has a 24-fret fingerboard and a fixed bridge, meaning the strings are anchored directly to the body rather than through a tremolo system that could affect tuning stability.

Hammett has used variations of this design since the 1980s. The current KH-2 is the result of decades of refinement—he has worked with ESP to adjust everything from the body contours to the pickup height to match how he plays. The guitar is available in several finishes, but Hammett's personal instruments are often black or dark colors that match Metallica's visual aesthetic.

The KH-2 is not a beginner's guitar and is priced accordingly. If you see one for sale, it will cost significantly more than a standard production electric guitar, reflecting both the brand reputation and the custom work involved.

James Hetfield's custom ESP EH

James Hetfield's guitar is a custom ESP EH model that does not have a standard production version. ESP builds these instruments one at a time to Hetfield's specifications. His guitars typically feature a mahogany body, a thick neck (thicker than Hammett's), and EMG pickups. Hetfield's instruments are often finished in black or dark metallic colors and may include custom inlays or graphics.

Hetfield's playing style is rhythm-focused rather than lead-focused, so his guitar is optimized for chunky, percussive rhythm work. The thicker neck gives him more stability when playing heavy, downtuned riffs. His guitars also tend to have a slightly different pickup configuration than Hammett's to suit the tone he is looking for in rhythm playing.

Because these are custom builds, Hetfield's exact specifications change over time. What he used in 2015 may differ slightly from what he uses now, as ESP adjusts the design based on his feedback and the demands of touring.

Amplifiers and tone shaping

The guitar itself is only part of the equation. Metallica's heavy, thick tone also comes from the amplifiers and effects they use. Both Hammett and Hetfield have historically used Marshall amplifiers, which are tube-based amps known for producing high-gain, distorted tones. A Marshall stack—a large amplifier head sitting on top of speaker cabinets—is a standard setup in heavy metal.

The distortion and effects are shaped by pedals and the amplifier's own gain settings. Metallica does not rely on digital modeling or software-based effects for their live sound; they use physical amplifiers and pedals that have been road-tested over decades. This approach gives them a consistent tone that is difficult to replicate with newer, digital-based systems.

How Metallica's tuning affects the guitar choice

Metallica typically tunes their guitars down from standard tuning. Many of their songs use a half-step down (Eb tuning) or a full step down (D tuning). Some songs go even lower. This downtuning makes the strings looser and requires heavier-gauge strings to maintain tension and playability.

A guitar designed for standard tuning may not handle downtuning well—the neck can develop problems, and the bridge may not stay in adjustment. This is why both Hammett and Hetfield use guitars specifically built to handle lower tunings. The neck is reinforced, the bridge hardware is rated for the extra tension, and the overall construction is more robust than a standard guitar.

If you are interested in playing Metallica songs on your own guitar, you will need to check whether your instrument can handle downtuning. Many modern guitars can, but older or cheaper models may have problems with neck stability or intonation when tuned down significantly.

Changes over Metallica's history

Metallica's guitar choices have not always been ESP. In the 1980s and early 1990s, Kirk Hammett played Fender Stratocasters and other brands before switching to ESP. James Hetfield used various guitars before settling on custom builds. The shift to ESP happened gradually as both players worked with the manufacturer to develop instruments that matched their evolving needs.

The reason for the switch was practical: as Metallica's touring schedule became more demanding and their tunings became lower, they needed guitars that could withstand the stress and stay reliable night after night. ESP's willingness to build custom instruments to exact specifications made them the logical choice.

If you watch Metallica performances from different eras, you will see different guitars. This is normal—musicians change equipment as their playing evolves and as technology improves. What matters is that the current setup works for the band's sound and the demands of their live shows.

Frequently Asked Questions

Can I buy Kirk Hammett's exact guitar?

You can buy an ESP KH-2, which is the production version of his signature model. It will not be identical to his personal instruments—those are custom builds with additional modifications—but it uses the same basic design and components. The KH-2 is sold through music retailers and ESP's website.

What strings does Metallica use?

Metallica uses heavy-gauge strings, typically in the 0.056 to 0.046 range for the thickest strings. The exact gauge depends on the tuning of the song. Heavy strings are necessary for downtuned guitars because they maintain tension and prevent the strings from becoming too floppy. Most music stores carry heavy-gauge sets designed for metal and hard rock.

Why does Metallica use downtuning?

Downtuning produces a heavier, darker tone that is central to metal music. It also makes certain riffs easier to play because the strings are looser and require less finger strength. Metallica has used downtuning since the late 1980s, and it has become part of their signature sound.

Do I need an ESP guitar to sound like Metallica?

No. The guitar is one part of the tone. Amplifier choice, effects, playing technique, and string gauge matter just as much or more. Many players sound like Metallica using different guitars, as long as they use the right amplifier, effects, and tuning. The ESP is what works for Metallica's specific needs, not a requirement for the sound itself.

Has Metallica ever used other guitar brands?

Yes. In the 1980s and early 1990s, Kirk Hammett used Fender Stratocasters and other brands. James Hetfield used various guitars before switching to custom ESP builds. The shift to ESP happened as the band's needs changed and as custom guitar building became more accessible to touring musicians.
