Mouthpiece for large-bore tenor trombone This is a supervised model by Jorgen van Rijen, principal trombone player of the Amsterdam Concertgebouw Orchestra, and is equivalent in size to the Denis Wick 6BL. Although it is positioned as a signature model, the inner diameter of the cup is close to that of a Bach 6-1/2, so we believe it is a model that can be recommended to anyone.
