Not sure if this is a problem or not. I have been doing my own tech work latley. I reinstalled the original pickup in my '57RI pbass. I had to resolder it a couple times as I had a cold solder. I have a hum if I touch the pole piece. Some of the poles hum more than others. Some wont hum if I am touching the stings some will. I dont recall this being a problem before I started messing with it. It could be I never really toched the pole peices before and it has always done this but since I have messed with it I fear I messed it up. The pickup sounds fine and ohms at 10.8k on my meter. I get a 11.5k reading at the output jack. Not sure if that is significant or not. Maybe a problem with one of the pots or cap? Like I said I'm new to doing this but wanted to try. Any ideas?
