emg 81/85

i have a zakk wylde epiphone les paul and have the chance to buy the emg 81/85 zakk wylde set fairly cheap. i just wondered if any one else has upgraded a similar guitar with these pick ups and how they have found them, what are the pros and cons?
the emg hzh4 pickups already in my guitar are ok, and certainly better than the standard epiphone pickups, but the neck pickup is fairly muddy and something with more clarity/definition would be great.
the 81/85zw set seems good as you get all the electronics in one pakage.

Get it and don't look back!
Your axe will take on a new life with active humbuckers.
especially the 81/85 combo.They are simply among the best.
