Large diameter, medium cup. Good for all-around use. 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. • 17.00mm cup diameter • Medium cup • Medium-wide, not too deep rim
