One of my friends has a gibson faded sg, and he asked me to take a look at it, and i cant figure out whats wrong with it. The problem is that the neck pickup has barely any output at all, and the bridge pickup has way too much output, to the point where it feeds back when any gain is introduced to the signal. There is a cracked ceramic cap in between the neck pickup's volume and tone knobs, i was thinking that might have something to do with the low output. He put pickup covers on the pickups, but i don't think that would do anything as extreme as this. Any help is greatly appreciated.
