Reprinted from HP Vincent Bach trombone mouthpiece. For large bore trombones. Known for its good response across the entire range and rich volume. The large cup produces powerful, resonant low tones. A classic model that has been used for many years. Silver-plated finish. ■ Trombone Mouthpiece ■ 1-1/2G ■ For large bore ■ Cup Depth: D Deep ■ Diameter: 27.00mm ■ Rim: MW Medium Wide ■ Backbore: 800S ■ Favored by bass trombone players, it produces powerful low tones. New: ¥11,800 I purchased this as a used item on Yahoo Auctions. It was described as having a gold rim, but I felt the gold plating was thin. I think it will be fine to use. Because of the old engraving, I assume it's from the 1980s-90s. I used it a few times, but have kept it stored at home since then. Please understand that it is sold as-is, with no claims or returns. I will accept price negotiations. Please feel free to contact me. Since there is no box, I will wrap it in bubble wrap for shipping.
