I need to talk to the place I bought it, but hopefully one of you can help me troubleshoot beforehand. I just got a new Reverend Club King. The A string has a loud, clanky buzz that is audible through the amp. I have tried a string change, adjusting the bridge, etc., but it's still there. As a matter of fact, with the action adjusted about as high as it can do, it still clanks and buzzes. It is a bad nut slot?
