ES Cups

The ES cup has a higher alpha angle than our standard S cup.  It has a smaller first cup radius and an increased beta angle to enhance articulation and sizzle in the extreme upper register.  This cup has a very small volume and is shallower in depth to maximize compression.

The ES cup has a huge sound in the upper register like all other GR Mouthpieces.

The throat and backbore were not compromised because the compression is achieved from the cup design.

Standard GR Rim and #1 Backbore.
