I started playing again (quite badly) with a Bach CR300 cornet. The horn is a beater, but it's much better than I am. Good valves. Now I've gone nuts and bought a Bach 184 on impulse. This one is also a beater -- needs repairs for small dents to the shepherds crook. Anyway, who do you guys recommend for a repair operation in Manhattan or Northern New Jersey ? Also, what are typical maintenance tasks, how often are they needed, and what are typical fees ? I'm thinking about the spiffy ultrasonic cleaning. Maybe getting lacquer touched up too ? Thank you all.
