I have noticed slight distortion or deflection (if that's the right word) in a really great mandolin right under the bridge feet (under D & A strings) where they meet the top.
The situation does not appear to be getting worse and the action has stayed the same. I've had the mando for three months. I can't tell if it is getting worse or not. The tone and playability are still excellent. Does this necessarily mean disaster for the future? Or should I quit worrying about it?
