Miraphone is a German mouthpiece maker. Its bright, resonant tone and refined, beautiful design are highly regarded by professional musicians. I am selling this mouthpiece because I am changing instruments. It has a deep cup, making it easy to play from high to low notes. The sound is slightly brighter. Perfect for wind bands. [Specifications] Cup inner diameter: 32.5mm Bore diameter: 7.5mm Cup depth: 36.9mm American model As shown in the photos, there is some wear on the mouthpiece receiver, but it does not affect the sound. Used for 2 years. Please understand before purchasing. I will polish, wash, and disinfect it before listing.
