The SHIVA combines both a step and roll-over baffle, and adds the Theo Wanne proprietary small chamber chamber. These features give the SHIVA huge power and edge making it suitable for Rock n' Roll, R&B or any situation where dynamics and power are important. Players who like high baffle mouthpieces will love the SHIVA because it doesn’t create a thin, nasal tone like a lot of other brands. The Hard Rubber version features the new, slim body style for added resonance.
