Guitar processor noise...? BZZZZZZ!

OK, I think I narrowed it down to 2 possible faults. 1 was the jack in the bass was 6 colors of ugly inside. This model but 30 years old.

This looks to be a stereo jack (3 lugs) that the guy put into the bass and the contacts inside didnt seem to show continuity to the cable end. Tip was fine, it as the ring/shield that wasnt making a connection. Then I started probing the cable and determined the braid/shield was possible open so I cut it back and tried to solder it back on with limited success, wrong tip on iron. The buzz has softened considerable but its still there, movement of the cable causes huge noise. The jack is jacked and Ill get a new one tomorrow if my electronics store has a deep panel threaded mono socket. The other cord was not good either so 2 new cords on order and that will give me a chance to attempt to reterminate the old cables with 4 new untarnished ends.
