C* Cups

The C* Cups feature the GR Classic Blank, GR Standard Rim, and GR #3 Backbore. 

The C* was designed for all-around Bb use featuring a higher alpha angle (similar to M cup) and a larger cup volume.  This design allows for added lip support and efficient playing characteristics throughout the range of the trumpet. 

The C* has an improved throat entrance over older "conventional" C cup designs which allows improved articulation, accuracy, and efficiency, along with a pure core of sound not found on most traditional mouthpieces.

The C* has a beautiful full sound with excellent projection, as well as, the ability to blend in any situation.  The C* will be a great choice for the student, amateur, and professional.  The C* has been use successfully on the D/Eb trumpet as well as the C trumpet. 

If you play a very open set up and require more resistance an excellent option is the C* cup with the GR #2 Backbore.

All the C Series (C*, C**, and C) have the same rim, alpha angle, L1, and 1^st cup radius (R1) to provide easy accommodation when switching between Bb, C, and D/Eb, as well as, accommodating other playing requirements.
