I can only support the suggestions to got to a good luthier. I had a similar problem with my HD28 a few months ago and asked for help in this forum. Someone suggested Trevor Durrant in Colchester and the luthier there ended up doing a great job on it.

As an aside I read with sadness that Trevor Durrant's guitar business was destroyed in a major fire at the Cowdray center in Colchester a couple of weeks ago. My best wishes go to everyone affected there and I sincerely hope the business will be able to recover.
