since you have a solidstate amp, you're not going to reacreate the sound because i believe that kerry and others use tube amps. you can fiddle around with the controls, turn the pre-gain up and hope for the best, but i don't think you're going to be able to do it perfectly
To improve technique and of course trying to keep all as clean as possible. I know my own limits and speed limits and so on I never play anything I'm not capable of. That wouldn't make any sense. After three years of playing I tried to play everything as fast as possible and that sounded, I would say, like shit, and I didn't realize that if I'd play bit slower things than I was capable of playing then everything would sound much better.
