My 1979 Les Paul Custom seems to be wired a bit differently that other Les Pauls I've seen. It's the era when Gibson surrounded the electronics in a metal housing. I'm running into some noise issues lately. No hum but high end rizz. If someone has a Les Paul from a similar year and could post a picture of the guts, I'd deeply appreciate it. I'd also appreciate any insight as to how to make the guitar a little less susceptible to noise. Thanks in advance!
