Tenor Trombone Mouthpiece for Small Bore Size is equivalent to Mount Vernon Bach 11C Amidst the numerous mouthpiece manufacturers, there is a craftsman who consistently produces high-precision mouthpieces. His name is Joe Marcinkiewicz. He once gained immense support across genres with the brand MMP, and he continues to create mouthpieces in his workshop, now located in Oregon. The remarkable feature of his mouthpieces is that the sound does not become thin in the high register, allowing for maximum control across the entire range, and enabling the instrument to resonate efficiently. This is likely the result of his own experience performing with Stan Kenton Orchestra and Don Ellis Orchestra, as well as actively incorporating the requests of top-tier artists, mainly from the West Coast. The Marcinkiewicz mouthpiece, completed through the fusion of the craftsmanship of the good old days and the latest computer technology, will greatly expand your potential.
