This is a detachable bell Hoyer 4801 that has had the lacquer removed and was just cleaned and adjusted here in our shop. It's ready to go and plays beautifully, with a DARK sound! The compression score is perfect at 0.1, and there are only a few very minor dings to be found. Basically this horn is in perfect mechanical condition! The grey detachable bell suitcase is quite small allowing you to bring it with you wherever you go. Quick change to make the horn sit in Bb if you wish.
