Northern Brass 4-63***** Trumpet Mouthpiece .630 inner diameter
This model has a slightly larger cup volume than the ****. The shape allows more lip into the cup with a slightly broader 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 6a4a the Shew models and similar shallow mouthpieces.The GR #1 back bore keeps the sound focused and good flexibility and upper register capabilities. The #4 rim is semi flat and similar to the GR e rim but with less overall width.
Please see the Northern Brass Mouthpieces Description section for more info on the rims and cups.
