You're not alone there. To me, metal is painful listening. To each their own, however. Have you demoed Guitar Rig 4 yet? I like the direction they went. Much quieter than 1,2 or 3. Several useful presets. I have demoed Revalver. I like it but there is noise. I want it dead quiet when I stop playing. I've demoed (and own a version of) Amplitube. Noisy. GarageBand, not bad. A bit noisy but not bad.
