Do any of you know anything about this mouthpiece and it's specifications?
I purchased it used but it is not listed at GR website.
It is a 3C of some kind, but its definitely different.
Thanks! |

Why not just ask GR?

This is a custom mouthpiece made for a particular customer. If I am correct, this is one of a few we made for him. Is there a program number on the mouthpiece...most likely a 4 digit number engraved on it near the GR logo? If you have that number, I can give you the specs. If you are not sure, just take a pic of the engraving and email it to me: grmouthpieces@gmail.com

GR found the info:
This mpc is not a 3C. It is a KR3MC-#3BB program 1277 08-11-2003
The rim is from a customers rim parameters that were fine tuned for him. It has a softer bite, the high-point is moderate, outside and OD is similar to most 3C style mpcs. The alpha angle is higher than (a 3C), it has a moderate 1st cup and a lower beta angle. This is a deep cup and follow the math of the GR C* parameters. Volume is .0821". Diameter is .658 and r4=.6745" see the GR specs to compare the r4 dimension. The cup is based off the GR C* series.

| Terrific. Thanks. There is no program number. C* makes sense. It plays a lot like my 67C* with a softer bite. It works very well for me, even though it was made for someone else. |

Was that guy's name like Dan Kapralian or something? I think I remember him from...hell, somewhere. It was online, and the internet all kinda bleeds together.
