I'm pretty sure they use JCM800s, almost certainly with ODs in front at all times. They use strats with stacked buckers I know for sure.
I don't give a shit if you listen to me or not
they use rack equipment. Im pretty sure they use Marshall JMP preamps and Marshall Poweramps of some sort. Back in the day they probably used JCM 800s.
Peavey JSX
Marshall 1960A
Ibanez S470 DXQM
Boss DD-6
Dunlop Original Crybaby
Marshall stuff. Pretty much a JMP-1 preamp with a marshall power amp but I saw Dave use a JVM or a JCM 2000.

In the Guitar World January 2007 issues "Dragonforce, Trivium, Megadeth, and Lamb of God Show you how to SHRED!", it has Dave Murray's set up. For those without the mag he uses two Marshall JCM 2000 DSL100 amplifiers, a huge rack, and Strats with Duncan hot rails. I won't name all the specifics. Oh and the 412 cabs have Celestion G12 "Vintage" 70-watt speakers.

That should give you and idea.
Why are some of you guys assholes , i mean we all love the guitar and the music that comes with that i mean why not be mean to the people who listen to rap
