Medium shallow combination "V" and bowl style cup. Our Signature Trumpet Mouthpiece outsells all other models as it lends itself well to all playing situations from jazz to symphonic. This trumpet mouthpiece model has established itself as the most popular for all around playing situations. This trumpet mouthpiece is designed to allow it to be more free blowing without the necessity of reaming to a larger bore size. This is important because the quality of sound remains the same without the risk of losing focus sometimes caused by playing too large of a bore size.
