When I saw them live they were usually using Mesa Boogie Rectifiers. One guy was using a Dean Dimebag guitar with EMGs in it, if I remember correctly, the other one was using a strat with a humbucker in the bridge. Next time, strat guy had quit the band, Dimebag guy was still there, same rig, they had a guy with a Red Jackson Warrior. Time after that Dimebag guy again, same rig, second guitarist was using an RR3 with EMG in the bridge, Peavey Classic 120 power amp, Mesa Boogie Triaxis pre.. I think they're using Madison
