The JodyJazz DV Bass saxophone mouthpiece is designed to give the Bass Saxophone a more immediate response.  From the JodyJazz website:

“The mouthpiece is based on our popular DV model but has several modifications, the most significant being a very deep chamber tuned to the Bass sax and a new feature I’m calling the hyperbolic chamber which rounds out the tone. Importantly also, the DV Bass mouthpiece uses baritone sax reeds! Bass sax reeds are hard to find and cost more but the DV Bass uses baritone sax reeds, so no need to search out bass sax reeds.”

Comes with JodyJazz Power Ring ligature and Protec mouthpiece pouch.
