This is a mouthpiece created by Brass Lab Momo, a dead copy of the Denis Wick SM3. Mouthpiece based on the Denis Wick SM3. Unplated, unlacquered, with acoustic treatment and finishing. It has the wide range of expression and sound of the SM3, and because it is not plated, the player's intentions are even more easily conveyed. The acoustic treatment reduces stress and makes it easier to play the instrument. The bore is slightly larger at 26.4, but it is easy to control.
