2013 SC245. 57/08 pickups. The bridge pickup is very weak. The previous owner had moved the neck pickup height down flat with the surround ring. The bridge pickup height is correct. With the bridge pickup on 10 the neck pickup has to be set at 3 to match volume. I took the control plate off and everything appears untouched. The one thing I did notice is that passing wire braid may be touching the solder point on the volume pot. Would this be enough to cause a partial ground out? Suggestions? Or should I just take it down to the shop? Thanks.
