ok, so my bass has a buzz. when i touch something metal on it, pots, input jack, yadda yadda yadda the buzz is almost non existent. i am assuming that it isn't grounded. when i brought it in to my tech he said he didn't see a chamber that was routed for the ground wire to the bridge. which i found odd. so on a hunch i took of the strings, removed the back cover and took off the screws from the bridge. no in the routed space where the pots are located i found a black wire in a small chamber that was routed under the input jack chamber. so now i remove the bridge to find that it leads to the bridge. but am confused because it seems as though it should be grounded, but its not. so i'm not sure if the bridge is metal or if its not soldered properly. but either way i think i can be grounded. the bridge by the way is a badass bass 2, if that helps any. so my question is, based upon the story, what do you think the problem is and what would the solution be? seems to me like i should have it re soldered with a new wire. but i'm just looking to see if i'm on the right track.
