hi biggy...i'm glad you like my stuff..thanks.
It depends on what i use...if it's East West MOR or kontakt. If it's kontakt it's for a raw and basic sounding guitar or bass routed through guitar rig.
Or to try another instrument combined with guitar rig...experiment with sounds, only cuz guitar rig is a amp vst, doesn't mean that it has to be a guitar or bass you plug into that amp

And i don't have a particular preset using for myself...i usually load up a brand preset and tweak the amps the way i want it to sound.
