Our most powerful alto mouthpiece, the SHIVA combines both a step and roll-over baffle, along with a very special proprietary small chamber unlike anything ever made before. Theo has spent years in research and development on this model to ensure it is a classic in history. The SHIVA 3 has been completely redesigned and is very different than prior models. It is really a special mouthpiece, with power and projection unheard of before, making it suitable for Rock n’ Roll, R&B, Jazz, or any situation where dynamics and power are important.
