For Kill em All it seems as if they seem to have just cranked everything up. For Ride The Lightning I found that this setting works well. bass=10 mid=4 treble=7 presence=10. For Master of Puppets just scoop the mids and add a little more treble it you want. I never really liked the tone of And Justice For All. It sounds wierd. They multi-tracked everything. You'll just have to play with your EQ and come up with something. Some songs appear to have the mids like some of Hammett's solo's and some have the mids scooped out.
