AC30 may be better then other amps for that, but playing technique? how would you acomplish that with just playing other then just hitting the strings harder, and angle of the pick for a little more gain? i'm not trying to be a wise a&s or anything, just curious what playing techniques would acomplish this, i've been playing for a very long time and was never able to get the thickness in the higher octaves to my liking, (amps or modelers)using the same sound for rythm and leads, with the Axe FX i have diferent patches for different positions of the neck, and switch between them, even on the same song when possible.
