Frequently bought together:


The rim contour is slightly more rounded than the GR Standard rim, plus it has a softer bite radius.

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 1st cup allows for ample lip room.

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.
