GREG BLACK 11C L Trombone Mouthpiece - Small Bore This mouthpiece combines a substantial weight with a light, small-bore trombone, creating a mellow, classical sound. It's also a very easy-to-play model for those who want to perform in various genres, including jazz. It has been used very little, so it's in relatively clean condition with no major scratches. It does not come with a box, so it will be carefully packaged and delivered via Takkyubin Compact.
