Used Cerveny CBB693 (ABB on the bell for Amati Kraslice) Kaiser 6/4 BBb tuba with 4 rotary valves. Fair condition with a minor dents, scratches, and lacquer wear here and there. There is also some oxidation under the lacquer over several areas of the tuba, but is really nothing to worry about. This tuba was just serviced, cleaned, and repaired in our shop. Everything works as it should, and it plays nice. Includes original case and mouthpiece.
