Holy crap, what a terrible story. They're going to try to fix that, but I'd be amazed if it ever sounds the same.
I remember seeing a show on Stradavarius and they could never fully determine what made them sound so much sweeter than other violins. They said he used a few different types of very dense old growth wood for various parts of the instrument and they also speculated that his secret varnish, the chemical he used to keep pests out of the wood, or even the fact that it was stored in seawater during the journey to Italy contributed to it. It was pretty interesting, even though the more they explored the secrets, the more it sounded like a chance happening then some intentional technique that made his instruments sound better than other violins.
