Vito student clarinets are equipped with an exclusive feature for the student, the Positive Radial- Alignment Guide. (PRAG) This patented guide enables beginning clarinetists to assemble the instrument correctly every time. If the instrument’s upper and lower joints are not properly aligned the bridge mechanism which links the keys of the upper and lower stack may not work properly. This could cause some notes to sound unfocused or not at all. PRAG provides a fail safe method to ensure proper alignment of the upper and lower joint every time. Currently Miller’s have this clarinet available in the new Selmer Cargo Case, a very durable case which also stores a cell phone, CD Player, IPod, and aother accessories important to the musician.
