The cork may need to be replaced. I had it worked on during a COA two years ago, but I have been not playing on it since then. When it was COAed the technician removed a pin-tip sized dent from the body, just under the Mancke logo. If you hold it up to the light, you can see on the metal that it has been worked on.I do not believe that this affects the sound, but if you do, I you may return it.
