Yamaha Tuba Mouthpiece Jim Self

Inner Diameter (mm): 32.86; Contour:standard; Thickness:semi-thick; Cup Depth:standard; Throat (mm):8.00; Backbore:standard; Description: Jim's mouthpiece embodies his long experience of playing literally ALL types of music in highly demanding situations. Jim doesn't like changing rims, so he uses the same mouthpiece on all his tubas. It is a medium large rim that is comfortable to play over the many hours a day that are required in his work. The cup and backbore are rather large for the best combination of a good centered attack and a warm, alive sound.
