I purchased this last week. I am selling it because I mistakenly bought the wrong model. There are no dents on the shank. This mouthpiece was supervised by M. Becke, a trombone virtuoso. With its large cup and bore, and a thick, sturdy rim, it produces a rich sound. For large bore trombones, silver-plated. 6-1/2M 25.40mm 7.50mm 6.55mm ML Retail price: 15,000 yen ---- "I purchased this around 2022 and used it for a while. It shows signs of use overall." ◆Please read the profile carefully and purchase only if you agree to the terms.
