Horrible!! In September 2013, we took my daughter's Yamaha trumpet in for a minor repair. In January, they still had not repaired it. In February, when we returned again not only had it NOT been repaired, they had somehow caved in one of the valves. They did not charge us, but in no way did they offer to try to make it better or even apologize for the additional damage they did. A completely shameful way to do business. Customer beware.
