If you aren't sure, go with a Jazz neck and JB bridge. You'll never go back. I promise you right now you'll probably love it. EMG passives can't even begin to compare.
If we were comparing the JB to the 81 we might have a discussion. But the JB will take on any passive EMG any day of the week and twice on Sunday.

As everyone else said, dont get the passive emgs. However, if your looking for very awesomely high output almost like an active EMG that is actually a passive, check out the Duncan Distortion, its incredible!
I'll echo that. If you're considering EMGs, go with the active ones. Otherwise, Duncan, in my opinion, are the best sounding passive pickups in the business.
