EMG PHZ Passive Pickups!?

[Reynolds 101]

I have a Standard Fender P-Bass (Arctic White), and I am planning on getting new pickups.
My first choice that I heard were pretty good, are the EMG PHZ Passive Pickups (split for pbass).

Please give me your own opinion on what you think of these if you know anything about them.

They're probably about as good as what you have in there now. Maybe they'll sound different. Why are you changing the pickup? Just tinkering?

yeah kind of.
I want to get a nice compression sound from the pickups for slap and still be able to have a deep tone for finger playing.
