hi, there is a one thing of buzzing too, your pickup. first try to put it deeper in and if it does not help there is a way that helped a lot of people, me too.
try to take out your pickup and put ander it a similar sized 1-2 milimeter foam (like from the egg foam) and it helps. one guy told me this at Dean forum
try to go there www.deanguitars.com find a guy named Stone in the forum and ask him about it.
