Thank you for viewing. I am selling a trombone mouthpiece. - Brass Mont Blanc 5G (Heavy) - For large shank, silver plated - With box This is a trombone mouthpiece. - Cup inner diameter: 25.50mm - Throat diameter: 7.15mm Similar in size to a Bach 5G. I used it for about six months. There is a small dent on the neck (photo 2) that was present from the time of purchase, but it does not affect playing. There is some slight wear on the plating, but I think it is in good condition. Brass Mont Blanc, made by Granz. The shape and playing feel are similar to those of Greg Black. My personal impression is that it is easy to blow despite being heavy weight, it resonates well, and it is easy to produce high notes. Manufacturer's description: Instead of mass production, each piece is cut → test played → fine-tuned repeatedly, so the potential is fully realized, resulting in an unprecedentedly good breath and a mouthpiece with a lot of resonance. Retail price: 30,800 yen #trombone #trombone #mouthpiece Type...Trombone Accessories/Parts...Mouthpiece
