Hey guys! I just installed a pair of Ultra Jazz pickups and plugged it up and dug the sound right away. But as I put the thing through the paces I found that, with the bridge pickup soloed, the E and A strings were significantly weaker than the D and G. Do I have a bad pickup or is there some mistake I can correct in the wiring. The bass is a 2000 MIM Fender Jazz. I left the original VVT controls in place. This is a pretty straightforward install (or so I thought). The pickups were NIB, though I bought them from an individual...not a store. They were brand-spankin-new though, still hermetically sealed in plastic. The plastic jewel box had not even had the seal broken. Will Dimarzio honor the warranty if I am not the original purchaser?
