one possibility would be emg 60 on the neck and duncan blackout bridge. Other would be invaders both ways, but i'd like to have additional ideas since i'm not in a hurry.
The reasons for "new" pickups:
Actives have a bit sterile sound, they are good but they could be better. The JB has too "loose" sound, but otherwise its perfect. Problem with jb is that it is unsuitable for neck and it does not go well with invader which is great neck pickup, just too bassy! These are the problems with pickups that i'm familiar with. The korina has a sound between mahogany and alder. The wood is lightweigh and as such has great harmonic balance and makes the guitar sing. I do not want to loose the distinctive feel of the korina by using actives(though amp pushed into 100%THD makes guitar wood completely indiffirent).
BTW the hetfields jackson, that broke during MOP tour, had jackson pickup on the neck and duncan on the bridge. The 84 gibson had it's pickups changed from gibsons to duncans and later(87') to emg's. His first esp custom "eet fuk" had dual 81's just as the black esp that came during the Black tour. Hammett had his custom jackson built with 81 set and he changed the gibson pickups, that were on his vee, to emgs during the lightning(no, the subject is still of no importance, but the fact that i *need* to be right is).
