Mouthpiece for Large Bore Tenor Trombone This model was supervised by Jorgen van Rijen, principal trombone player of the Royal Concertgebouw Orchestra in Amsterdam, and is similar in size to a 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 think it is a model that can be recommended to anyone.
