Northern Brass 3-66**** Trumpet Mouthpiece .660 inner diameter
This has the medium shallow **** cup with the #3 rim which is similar to the standard GR rim but has a softer bite.There is a sufficient amount of what many refer to as "undercut" for chop room.. A great choice for those who bottom out on the 13a4a,14a4a, the Shew models and similar mouthpieces. Those who like the 3-66*** often add this model to their arsenal for when a darker broader sound is desired yet still efficient enough to tackle difficult trumpet literature. The GR#1 back bore is used.
Please see the Northern Brass Mouthpieces Description section for more info on the rims and cups.
