C-T Trumpet Mouthpieces

The rim is not a Standard GR rim! 

This rim has characteristics of an old 1C, although certain rim parameters have been changed to make this mouthpiece more efficient. 

The 67C-T mouthpiece was designed for the C trumpet, but it is also a good match for certain Bb trumpets.  The alpha angle is raised slightly to enhance articulation for a player that must work very hard to play a 1C style mouthpiece.  The 1^st cup radius or R1 has been slightly increased over older 1C designs to increase efficiency and provide a fat vibrant sound.

The throat bore is larger than the standard #27.  The Backbore is a #3 and a GR Classic Blank is standard. 

There is an option to have the 67C-T made with the GR Symphonic Blank that is slightly shorter and has a more open blow.  The 67C-T produces an incredible Orchestral Sound.
