Northern Brass 4-64***** Trumpet Mouthpiece .640 inner diameter
This has the #4 semi flat rim which is similar to the GR e rim but not as wide overall and a medium shallow cup.
The GR #1 back bore is used for a focused and versatile 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. Players who like this also like the 4-64*** and 4-64**** for extra efficiency and upper register assistance.
Please see the Northern Brass Mouthpieces Description section for more info on the rims and cups.
