64ES GR Trumpet Mouthpiece
• Standard GR rim contour: a balance of medium characteristics, this rim is comfortable and should be easy for most players to adapt to quickly. The width may feel a bit more generous than traditional rims and will aid endurance. Flexibility is good and articulations will be cleanly defined.
• .64" rim diameter, approximately equivalent to a Bach 7
• 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 to maximize compression. The ES cup has a huge sound in the upper register. The throat and backbore are not compromised because the compression is achieved from the cup design. #1 backbore.

64E-5 GR Trumpet Mouthpiece
• .64" rim diameter, approximately equivalent to a Bach 7
• E-5 cup: the rim has semi-flat characteristics and the highpoint is further from the bite than most mouthpieces in this diameter. The bite is medium sharp and the alpha angle is medium allowing for more lip freedom in the upper cup. This allows for improved articulations, flexibilities, range, and sound. The cup has a small volume and a unique throat entrance created by the GR Mouthpiece Design Program. The unique throat allows for good compression and articulation in the upper register as well as a big, fat sound. This mouthpiece has the GR #1 backbore. The 64 E-5 mouthpiece works well for upper register players that need more lip room. This rim has similarities to the Wick 5E and Schilke A4a rims.

Recommendations:

Try this mouthpiece if you are playing a GR 64Z* and you bottom out or feel like you shut off. Also, if you play a Wick 5E and want improved articulation, sound, projection, and intonation with a similar feel, look at the 64E-5. If you play a Schilke 10A4a and you bottom out or feel like you shut off, this piece may be an ideal alternative.

A great choice if the S cup doesn’t provide enough compression for range requirements and articulation, or enough edge to the sound. The SZ cup has the rim and alpha of the S cup and the bottom of the Z, with the GR #1 backbore.
