This is a Greg Black NY series mouthpiece, size "5", for large shank trombones. This model is very popular with orchestra players, ideal for those who want a playing experience that's not too heavy, like a 4G, but still want a richer sound than a 5G. I found a different size suited me better, so I haven't used this one much, and it's in good condition. I'm selling it to raise funds for new equipment. Size: NY 5 (Between Bach 4G and 5G) Shank: Large Shank Blank: Light Condition: Rim/Cup Interior: No noticeable scratches, in good condition. Shank: Used very little, with few scratches. Plating: Used very little, in beautiful condition. In my opinion, it's in good condition, but please understand that it is a used item before purchasing.
