So i have a Les Paul and it has a buzzing issue. i checked and double checked all the wiring and everything is ok. I have been playing this guitar for a few years and this just happened. So on a whim I plugged in a regular guitar cable and checked to see if the tip and ring were touching with the bing option on my multi-meter. and sure enough there was! the buzz goes away when i am touching any metal parts but there is still continuity on the guitar cable. what is going on??? I spent at least 3 hours on it already. All of the sudden the buzzing is gone. Any ideas?
