I realize that this is an older thread, but in case someone else does a search and finds it, like I did, I would like to add a reply. I recently bought a used Epiphone Chet Atkins CE and as the original poster stated, there is an annoying hum. The hum would go away when you touched the jack plate. I knew this had to be a grounding problem so I went searching for a remedy. This is how I fixed mine and now it is quite as a mouse. I drilled a small hole (1/16 or an inch) in the metal 9v battery holder near the edge and ran a small wire through it and looped the wire back around and twisted it to itself then soldered this so the wire would remain in contact with the metal battery holder. Solder will not stick to the metal battery holder, not even using flux. I don't know what type metal the holder is, but this is the reason I drilled the hole and just looped the wire around and twisted it to itself. I then soldered the other end of the wire to the negative wire (black) on the square pin block that the piezo plugs into. Just to be clear I am talking about soldering it to the black wire that comes out of pin block and goes to the preamp board, not the black shielded wire that comes from the piezo. This completely removed all hum from the guitar. I hope this helps someone.

Edit: I have taken a picture of where to solder the wire and drawn 2 arrows to show each end of the wire. Hope this helps.
