Trombone Mouthpiece Heavy series

  • As a result of many years of research with musicians, we have conducted various research with the musicians as the concept of development, with all the conditions for satisfying the musical expression to the maximum when the musicians play brass instruments. We have succeeded in digging down the hardness and metal crystal grains to the micro level and controlling them to the best metal state to play it. Please try it out with your own hands, as everyone will be able to bring out the maximum musical expression with minimum effort. I think that you can feel the feeling of wind performance that you have never met before.
