    I have a FBB bass custom with obp-3 preamp. It was working fine until I tightened the input jack. Now I heard like humming/buzzing from the bass but when I touched any knobs or string, the noise was gone. Did I do anything wrong? Any suggestion?

    Thanks,
    Max

    sounds like a ground wire came disconnected, do you see any floating wire ends in the cavity?

    If you didn't hold the jack from inside the cavity as you tightened the nut, you may have twisted a ground wire loose. Look real close at the wires at the jack solder terminals.

    FWIW:

    Tres, and that's a fact - Jack!

    Hum increasing touching strings/etc. is a red flag for ground issue.
