Check to see if you don't have the ring and tip connected the wrong way on the jack. You can see which one is which by picking in a patch cord and then use a meter to check for continuity between the tip on the other end and the two contacts on the jack.

But it sounds like you have them swapped.
 
thanks but i tried that already and the buzzing noise went away so im pretty sure the way i had it first was right. afterwards i rewired the whole thing from scratch and nothing changed. what are the important connections for the pickup? is the ground wire the problem?
