LD4 = inner diameter + .637″ or 16.18mm
The LD Model is the shallowest and most open in the Studio Master Series. The shorteness of the overall length with the #27 bore (.144 or 3.65mm) combined with a large back bore make this model the most free-blowing lead piece available. If you have been accustomed to playing on mouthpieces that have larger bore sizes, the LD models can offer the same open blow you’ve come to feel comfortable with.
