These are nicely made copies of the old Mt. Vernon Bach mouthpieces, made in USA by Chuck Slinkard (owner of the Superslick brand). They just come in a few popular sizes, and many teachers are recommending them to students, because when one is new to the trumpet, a 3C is a 3C is a 3C. So when they recommend a mouthpiece, they know their students can get the right sized one of these for a very affordable price.
Available in sizes – 1.25C, 1.5C, 3C, 5B, 5C, 7C, 10.5C
ABI Price: $49.95
