GR Technologies - Today's most technologically advanced brass mouthpieces.  The versatility in design has GR's being used by serious students and educators, to the world's finest Symphony Orchestra trumpeters and the top studio musicians in Los Angeles.

With hundreds of standard models, and thousands of custom designs, GR has a mouthpiece to match you, your horn, and your musical needs. 

The GR No-Discontinuity design allows for a perfect blend of rim to cup, to throat, to backbore for optimum performance.  Crisp articulations, a rich vibrant centered sound, outstanding intonation, easier upper register, and a fatter lower register are some of the benefits of this design.
