Northern Brass 4-66*** Trumpet Mouthpiece .660 inner diameter
This model has the #4 semi flat rim which is similar to the GR e rim but not as wide overall and has the shallow *** cup. The GR #1 Back bore is used for a focused and flexible sound.
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 shallow mouthpieces. This is identical to the previous 4-66GP*** model.
Those who like this model also like the 4-66****.
Please see the Northern Brass Mouthpieces Description section for more info on
the rims and cups.
