That is pretty much the same kind of sound I get with sims no matter what I do and I use an emg 81 with an alder guitar. Kind of a grainy top end that's impossible to get rid of, and it has little to do with your actual playing which would sound much better reamped through an actual rig. Maybe I'm just getting tired of sims and they are all starting to sound the same. You've done well, as far as a sim goes, I'd say.
