This is a BACH trombone. I purchased it about 10 years ago and used it for 5 years in a brass band, and it has been dormant for 5 years. There are some areas where the plating has peeled off, scratches, and dents on the bell. I think it can be used without any problems, but please refrain from purchasing if you are looking for perfection. There are two mouthpieces, but the metal fittings have deteriorated over time. The case has also deteriorated over time, but it can be used without any problems. Since this is an amateur inspection, please forgive any oversights. I cleaned it earlier, but since I am an amateur, I have avoided professional cleaning that could lead to damage to operability or scratches, so please understand. We cannot accept cancellations, returns, or refunds after purchase, but if you have any concerns, I will respond to the best of my ability, so please comment before purchasing.
