David Goodrich is a wonderful character. He doesn't always make it to the phone in time to pick it up, but he responds quickly to e-mails so I'd recommend that route for communication. And he is by appointment-only now, so don't just show up and expect to be seen.
All that said, I doubt there's a better place anywhere to get your instrument repaired. He is extremely knowledgeable and downright passionate about violins, violas, and cellos. I own one of his violins and I take it in every year for a check-up. He holds it like a baby, taking his time to inspect everything, then hands it back and asks me to play something. Then he makes a face, takes the violin, and adjusts something before asking me to play again. Repeat for up to an hour. It's amazing how the tiniest tweakings make such a massive difference in sound quality! My violin has literally doubled in value since I bought it, and I'm sure it wouldn't have matured quite so magnificently without the yearly adjustments. Plus, it's really fun to get to try all sorts of new things- from strings to chin rests to bridges of varying heights- and then learn about why they change the way your violin plays. read more
