NY Classic 6FL Special Flugelhorn Mouthpiece
Product Details
This is a B shank, which is rarely found on the market.
The shank is designed to fit small shank flugelhorns, including Bach and Courtois models.
The inner diameter is 16.70mm according to the official website.
It has a deep V cup and feels slightly longer overall.
I found it to be easy to handle, suitable for classical, jazz, and wind ensemble performances.
Regarding the special designation, there is no information online for this specific model number, but it is likely designed with the ideal 6 sizes in mind, similar to other special models.
