Ultimate feel and stellar sound.
Large bore mouthpiece for trombone. The classic euphonium model, also good for powerful trombonists.
Dennis Wick's heavy top mouthpiece uses a completely different principle in order to prevent the trumpet's vibration from feeding back to the player, transmitting all the energy through the bell. This gives a much more powerful sound when needed, more security in the high register and more control and focus in all registers.
