New pickups

[METaLLiKka7447]

Ok i have a 5-string Washburn XB-125 http://community.webshots.com/photo/101839659/101840110jDmFPZ
and there are some problems i want to fix,
i need (a) new pickup(s), the bridge pickup that i have gets feedback and a low buzz which is annoying because even though i play metal with it i like a nice warm Clean tone,what is a good pickup for that, my neck pickup is pretty good and i think im gonna keep it because it gets me that warm clean tone, i dont like that trebely sound you get from the bridge pickup, I dont care if its active or passive, please give me some suggestions, its a soapbar if you didnt look at the picture, and is there a way to put more tension on my low B string I have Light D'Addarios on it and it still is kinda fuzzy (not fret buzz)

I like dimarzios and emgs but I couldn't view the page so I can't see the pickup config. So if its two j's then I would go with dimarzio but emgs would best I think for the soapbar type I think. I dont know if emg makes j pick ups or p style pickups, I have never used seymour duncan but I suppose there good but I don't know from experience, I have never used them. hope that helps
