Giddings & Webster trombone/euphonium mouthpiece, Kadja. Made of stainless steel. It has good response and allows for comfortable playing. New ones are very expensive, and it's a brand that doesn't often appear even in the used market. The condition of the mouthpiece is as shown in the photos. Due to use, the tip of the shank is slightly warped, but I have used it without any problems. Please purchase only if you understand that this is a used item. Specifications: Inner rim diameter: 25.70mm Throat: 7.239mm The deep funnel-shaped cup allows for a very large sound without losing articulation or clarity of pronunciation. The official website description is as follows: -- The Kadja is one of our most popular tenor trombone mouthpieces. Rim 1.012inch, and throat .285inch. This mouthpiece has a deep funnel shape cup. Designed to carry the largest of ensembles. Great mouthpiece for those who are looking for a huge sound without loss of clarity and articulation. Kadja is a steady breeze off the sea in Bali.
