I recently pick up a Geddy Lee jazz bass. I play with the vol controls all the way up. I noticed that when I turn either one down I get a buzz, and then when I turn it back up it goes away. Kinda seems like a ground issue but not sure. Could it be the vol control pots? Any idea's? I am sure I could take it back to GC, but not real confident on the repairs, especially if it is something I may be able to fix. Or, like my guitarist said.... It doesn't make noise all they way up, so what's the problem

But I really would like to have it quiet at all postions.
Thanks,
Steve
