YAMAHA Roger Bobo Solo Tuba Mouthpiece Yamaha BB-BOBO-SOLO-ST I used this for a short time when I first started playing the tuba in a general band. I thought it might suit me since the instrument was small, but due to my lack of skill, it was difficult to control, and I only used it for a short period. I am selling it because I don't plan to use it in the future. The condition is good with no major damage, but there are some minor scratches and dirt. If you are concerned, please consider another one.
