62 Primal 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.
• .62" rim diameter, approximately equivalent to a Bach 10½
• Primal cup: basically a combination of the GR M and MS cups. The alpha angle feel is similar to an M but with slightly more support. The cup has a medium/high compression like the MS. This combination really screams but with a huge fat sound that can be sweet if you back off. The best thing about the Primal 62 is that it works incredibly well with the following GR backbores:

The #2 backbore was the original Primal backbore. It provides a huge warm sound that can be powerful when pushed. This is the perfect backbore for tighter trumpets or for players who want a solid core to their sound, with fast response, but do not need an extreme upper register. Great for concert band and section work.

The #1 backbore provides the Primal 62 player with very fast attacks, a lower register that pops at very soft volumes, and an upper register that sparkles with a huge core. Ideal for all around lead playing.

The Primal cup with the revolutionary GR T-72 backbore provides many of our customers' favorite set up. Super fast attacks, high compression, an effortless extreme upper register that commands any ensemble, plus fast attacks and secure slotting all over the horn. This combination will support huge double C's all they way to the end of the night, consistently!
