Master of Puppets by Metallica — Amp Settings & Guitar Tone

Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.

To recreate the iconic thrash metal tone of 'Master of Puppets,' we'll use the Fender Mustang LT25's high-gain capabilities and the Squier Classic Vibe Stratocaster's bright single-coil pickups. The amp's 'Thrash Overkill' preset provides a solid foundation for the scooped mids and aggressive attack characteristic of the original recording. Adjustments to gain and EQ will help achieve the tight, articulate sound needed for the song.

What Metallica actually used

Recorded at Sweet Silence Studios in Copenhagen, Denmark, with producer Flemming Rasmussen. James Hetfield primarily used his 1984 Gibson Explorer for rhythm parts, while Kirk Hammett utilized a combination of guitars and effects for lead sections. The Mesa/Boogie Mark IIC+ amplifier, combined with a Marshall power amp and 4x12 cabinets, was central to achieving the album's aggressive tone.
