GR Custom Trumpet Mouthpiece - MX Cup/#2 Backbore - Gold - Excellent Condition
This is a GR MX mouthpiece with a #2 Backbore.
Insertion marks are visible.
The GR 66 Series cup diameter is similar to a conventional 3 diameter. The 66MX is a very popular choice for players looking for a more Medium-Large classical cup but still want to stick with the 66 option. The #2 BB makes it a bit of tighter blow but still is a good mouthpiece. I used this one on my C trumpet with great success.

I am asking a reasonable price for it.
