This is a single-rotor bass trombone made by Schenkelaars, a Dutch manufacturer. I used it for rehabilitation after a blank period, but I am selling it because I purchased a new instrument. ◎Specs Estimated to be 40-50 years old. ・Tuning: Bb/F ・Bell: Yellow brass ◎Condition After purchasing it at a used goods store, I had the dents removed, and the slide, rotor, and tuning slide repaired and adjusted at a musical instrument store. The lacquer has peeled off in many places except for the bell, giving it a vintage look. ◎Accessories The original hard case is included. It is made of wood covered with leather and is very durable. It has a texture similar to old German instrument cases. ◎Playing Experience Since it is a single rotor, it naturally has a lighter feel than a double trombone and a lighter sound, but it has a moderate resistance that makes you feel the thickness of the entire tubing. However, it doesn't have the heaviness or dark tone of so-called American instruments. The intonation is also not too bad, and it is easy to handle. It has been adjusted and is ready to use immediately. Please feel free to ask if you have any questions.
