Probably the most used trumpet mouthpiece size in the world. Used by school musicians and professionals alike. Megatone mouthpieces have the same rim, cup and backbore as non-Megatone models, but have additional mass which allows the mouthpiece to produce a darker, more focused sound. The throat on Megatone models is slightly larger to open up the feel and response and to allow more flexibility. • 16.20mm cup diameter • Medium cup • Medium-wide rim, lowered toward the outside. Medium-sharp inside, well rounded edge with a perfect grip.
