half the problem is
half the problem is that you used a preset slayer setting. Its ok if your just learning and thats that. its just that slayer is really over used and VERY generic alot of the time now adays. I myself try to stay away from it alot of the time because of that generic "wanna be guitar sound" Other then that though don't get discouraged. Keep it up and you'll find what your lookin for sound wise.
