Is Gibson allergic to putting some copper or aluminum tape on the underside of the control cavity cover? I live in an old house with a few ungrounded outlets, which unfortunately are the convenient ones to use, and the buzzing when using high gain amps dirt channels, Mark V 25 / Archon 25, was driving me nuts until I popped open the cavities on my studios and put two layers of aluminum tape on the plates undersides. Viola! Problem solved. I'm just wondering if Gibson does this on all their LP's? Thanks for any replies. P.S. I know ungrounded outlets are not cool at all, but I'm having a hard time getting my cousin, who is a master electrician, over to help me out.
