For the master of puppets album, Metallica was using Mesa Boogie Mark IIC+ amps. They are still popular with guitarists to this day and can be easily emulated with a modern high-gain amp. This video of their song master of Puppets will give you a reference of the right sound.
In the early 1980s, Metallica were watching the scene in the Charlton Heston movie The Ten Commandments when the Angel of Death kills the first-born son of all the Egyptians. "Whoa," bassist Cliff Burton said. "It's like creeping death." The group liked the phrase and quickly wrote this thrash masterpiece for their second album, Ride the Lightning. The song is told from the point of view of the Angel of Death and is full of references to the Book of Exodus. 781b155fdc
