    These guitars come with an output jack that has two contacts for the tip instead of one, and I have read of others experiencing issues with them as well. I encountered the same thing (really loud buzz if I would touch the cable at all)so I replaced it with a regular 1/4" mono jack that only has a single contact for the tip. This seems to solve the problem of the loud buzz whenever I move the cable around but now I have another issue.

    Whenever I take my hands off the strings I get some buzz that becomes quieter once I touch them. I've heard that this might be a grounding issue and I have tried to troubleshoot it but nothing seems to work. I looked at the wire Gibson had run from the PCB to the output jack and it looks like they have the ground come from the connector on the board > soldered to metal shielding on the cloth push-back wire that carries the signal > then the shielding was pulled apart and made into the shape of a wire to connect to the sleeve lug on the output jack.

    When I put the new jack in I soldered it the exact same way the other one was in there and now somehow it isn't grounded. I even un-soldered and re-soldered to make sure the connection was good. Still isn't working. I am just wondering what else I might try to fix it.

    You might want to trace the ground wire for the bridge. This usually takes the form of a wire that connects up the stop tail lug to the volume pot casing.

    Hmmm, that sounds like a good idea. I noticed when I opened it up that there was a bare wire coming through a hole in the side of the control cavity that goes to its own connector on the PCB. I assume this goes up to the bridge. Should I run a continuity test on that wire in the control cavity and the bridge? If those aren't connected is the next step to remove the bridge and try to connect them?

    I really don't like these pcb electronics in guitars, it's difficult to tell where something is going wrong. I may just have to take it in for repair.
