I know that when he reran the neg, it cleaned it up nicely. I am not sure about the ground paint either, that is just what he said. as soon as he opened up the back he said "There is the problem"...I just popped the back off of mine so i could look how he did it. He just ran another wire from the copper "sticker" to the ouput jacks neg. Hope this helps
Cool, thanks for the clarification. It seems that I've pretty much fixed it by adding some solder, but there is still some excess buzz when the treble is boosted. I'll try running another wire and see what happens. Thanks for the help!
