Theo Wanne GAIA 3 Alto MouthpieceThe result of the GAIA 3s new design is a freedom of play never before experienced in a traditional sounding alto mouthpiece! Easy to see innovations include the proprietary Shark Gill Baffle, which improves the airflow and opens up the sound. Harder to see is the redesigned baffle shape and chamber. Once you spend some time on it, you will find a dynamic range and flexibility not found in many other mouthpieces.
