Popping Dimarzios

Alright, so I bought a 1991-1992 74' Reissue MIJ Fender Jazz from a fellow TBer a few weeks ago. The nut was chipped, which he told me about. I got it into the shop to fix the nut and some tone knob problems.

Anyhow, I've got the bass back. It has a Badass II bridge and Dimarzio pickups. For some reason, the E string plays louder than the rest. Its not even the low sounds, its just that string. The A string low sounds are the same as anything else, except the E string.

In addition, slapping the E string and even a bit on other strings makes a popping noise like I'm slapping right over the pickup. Problem is, it makes that sound no matter where I thump. Its a real problem.

Anyhow, the bridge pickup is a lot closer to the strings than the other pickup. I tried to screw it in more but it... doesn't go. I don't wanna strip out the little screws, but it seems like its... screwed in all the way. So I'm not sure if that's the problem but I suppose I could take it off and then put it back on....?

Anyhow, if you folks need pictures I can post 'em. What do i do?! Do I get it in the shop and let THEM deal with it? Do I need new pickups?

 

That fixed it! Thanks!
