Master of Puppets guitar tone
Metallica · James Hetfield (all main rhythm guitars and melodic solo), Kirk Hammett (fast solo and last-verse reverse phrases)
Master of Puppets (1986). Recorded September to December 1985 at Sweet Silence Studios, Copenhagen, engineered and co-produced by Flemming Rasmussen; mixed January 1986 by Michael Wagener.
Dry, tightly down-picked Mesa Mark-series thrash rhythm with a lightly modulated clean interlude and a more mid-present Mark II-C solo voice
The rig Metallica used
Researched from interviews, production write-ups and gear histories — not guessed.
Guitar
Hetfield performed the four main rhythm parts, beginning most passes with his white Gibson Explorer while varying guitars and equipment between takes; the Explorer still carried passive ceramic pickups. Hammett's fast solo is verified on a Jackson Randy Rhoads V. The exact guitar for the clean interlude and Hetfield's melodic solo is unresolved.
Amplifier
The verified main-rhythm path is a Mesa/Boogie Mark IIC+ family lead circuit, likely the C++ revision, through the Boogie power stage. The title sheet does not support an always-on JCM800 slave; Rasmussen states that most guitars used the Boogie power stage and that the JCM800 exception applied only to unidentified solos. The clean interlude's amp is unresolved, so the evidence-bounded recreation uses the Mark IIC+ Rhythm/Clean channel rather than the lead model. Hammett directly identifies a Mesa/Boogie Mark II-C head for the fast solo; Hetfield's melodic-solo amplifier remains unresolved.
Cabinet
Two parallel guitar cabinets; exact title-track cabinet models and speakers are unresolved
Microphone
Six simultaneous microphone feeds: one Shure SM57 close to each cabinet, one B&K/DPA room feed per cabinet, and one AKG Gold Tube microphone per cabinet about 3-4 feet away at roughly 45 degrees, blended through the Trident A-Range console.
Signal chain
The order the original sound was built in. The exact settings get dialled for your own amp or modeller when you generate the tone.

Why we think this is right
Contemporaneous title sheets and direct Flemming Rasmussen and Kirk Hammett testimony place the main rhythm on a Mesa/Boogie Mark IIC+ family amp with the EQF-1 in its loop, the Boogie power stage, two parallel cabinets, and six microphone feeds. The title settings are preserved, while the graphic-EQ curve, cabinet models, speakers, and title-specific pedals are not invented. The clean interlude is documented only as layered clean guitars, so the Mark IIC+ Rhythm/Clean channel and subtle stereo chorus are labeled recreation choices. Hammett's fast solo is verified as a Jackson Randy Rhoads V into a Mark II-C; Hetfield's melodic-solo chain remains unresolved.
