im still a beginner at the guitar thing, but i was wondering was aspect of the playing gets you the really crunchy sounds kinda like in iron maiden - the trooper

kinda like in the parts where your galloping i guess is what its called...would that be your amp or your pickups or both??? I have EMG-HZ's (spare me the pup hard time) and a roland cube 30 watt amp
Bridge pickup, a metal-style amp model, high treble and mids, slightly less bass, and gain at about 5 or 6.
A dwarf might hear you. What then?

My Music
so my cube 30 on my metal stack, with my EMG-HZ's should be alright? its not active pickups or anything?
