Trombone Mouthpiece Heavy series

  • As a result of many years of research with musicians, the development concept was to satisfy all the conditions to maximize the musical expression when a musician plays a brass instrument. We have succeeded in digging down the hardness and metal grains to the micro level and controlling it to the best metal condition for playing it. It is kind to everyone and brings out the maximum musical expression with the minimum effort, so please take it in your hands and try it. I think that you can feel the feeling of blowing that you have never encountered before.
