The GR 66.5 Series Trumpet Mouthpieces were originally designed for trumpeter and educator John Almeida. These mouthpieces became so popular that GR decided to add them to the line.

The GR 66.5 Series Trumpet Mouthpieces are available as a standard order with the GR Almeida rim .

The M cup has a large diameter that features a smaller 1st cup, medium 2nd cup, and a very long and deep throat entrance. This cup has a large volume yet it is very efficient. The sound is rich and brilliant through the range of the horn. This cup is very versatile and allows the player to shade and color the tone.

The MS cup has a medium volume with lots of sizzle and power.  It's an excellent choice for any commercial venue.  The alpha angle is medium high and the 1 st cup allows for ample lip room.

#2 Backbore standard on MS and M Models.

#3 Backbore optional on M cup for C Trumpet use.
