Unlike some other manufacturers [who use trombone mouthpieces repurposed for baritone], the Steven Mead SM4X Bb Baritone mouthpiece is designed to work specifically with the conical bore of the instruments. They have more open backbores and a funnel shaped cup that creates a warmth and richness in sound that no other manufacturer can achieve.
