This is the beginning of what I hope is a video series on my channel called the "Horn Resurrection" series. I plan to resurrect several horns in the next couple months (in line are an Alexander 200, N-series Conn 8D, and Meister Hans Hoyer 7801). I don't do this kind of work full time, but I do enjoy it when I get the chance, and hope that it is enjoyable for you to watch.
This first horn is a customer's Mirafone compensating descant that has been sitting for around 30 years without ever being out of the case. The horn was very dirty and needed a good clean, valve alignment, and just general maintenance. It probably took about 3-4 hours that I spread out over the course of a few days. The end result is a fully functional, beautiful, very light and sweet sounding descant that plays great.
Enjoy!
