    I have a 2005 Fender P bass, MIM, all stock. I haven't played it in a few months. I picked it up today and suddenly I'm getting a major buzz. I've tried it on two amps with two different cables, and I get the humming/buzzing each time. I didn't change anything on the bass and I'm using it in the same room, same outlet.

    Any ideas? Do I need to take it in?

    Sorry if this topic has been done to death, but I did do a search on it and couldn't find an answer where the person with a buzzing/humming hadn't recently changed pickups or done something else to the bass. This happened suddenly.

    Thanks in advance!

    Just did some more testing and determined its a grounding problem. Not sure why this would suddenly occur or how to fix it.

    Probably a cold solder or loss of contact with the bridge.

    Does the buzz go away, get louder, or remain constant when you touch the bridge/strings?

    If it goes away = Shielding

    If it gets louder = grounding

    If it remains constant = could be a deeper issue, but check the ground wire running from the bridge to the control cavity.

    Looks like it's shielding. How do I fix that?
