Trombone Mouthpiece Heavy series

  • Beginning with the concept of creating a product that satisfies all the requirements for brass players to realize their maximum expression in performance, Momo, after years of collaborative research with performers and the micro-level investigation of the hardness and crystallization of metals, has succeeded in creating the optimum metalliferous state to realize such expression.

    Our mouthpieces can help you to discover a new level of musical performance and ease of playing. Please give them a try.

    The sound gains a core; response and release are excellent

    Smooth airflow; clear tone Easier lip slurs and control Broad dynamic range from ppp to fff; easier musical expression
