Northern Brass 3-65**** Trumpet Mouthpiece .650 inner diameter.
The medium shallow **** cup with the comfortable #3 rim which is similar to the standard GR rim width but with less bite.There is a sufficient amount of what many refer to as "undercut". A great choice for those who bottom out on the 13a4a,14a4a the Shew models and similar mouthpieces. Those who like the 3-65*** often add this model to their arsenal for when a darker broader sound is desired yet still efficient enough to tackle the most difficult trumpet literature. GR#1 back bore is used.
Please see the Northern Brass Mouthpieces Description section for more info on the rims and cups.
