What Is the DV Tenor Saxophone Mouthpiece?

Jody Espina has introduced the concept of Golden Section Proportions to the art of high end saxophone mouthpiece design. This perfect chamber/bore/facing combination will result in an extraordinary playing experience for you.

Three Goals in Creating the DV Series of Saxophone Mouthpieces

1. To create the most efficient sax mouthpiece possible. That means that there are more harmonics present in the sound and therefore the projection of this Tenor sax mouthpiece is huge.
2. To eliminate the annoying shrillness that is associated with loud bright Tenor saxophone mouthpieces.
3. To have a big fat mid-range and bottom end that has never been present before in a Tenor sax mouthpiece with strong projection.
