We offer 3 options for the Blessing Mouthpiece: a 6 1/2 AL with small shank, a 6 1/2 AL with large shank and a 12C. The 6 1/2 AL with small shank is the most common sold as this is the size recommended by most Orange County band directors, and the small shank is what fits standard student lined trombones and baritones.
 
The difference between the 6 1/2 AL and 12C sizes is the size of the mouthpiece rim, and cup depth. 6 1/2 AL is our most popular choice, and is a really great, medium sized mouthpiece that is quite versatile for all styles. 12C has a smaller rim and cup size. It has a slightly brighter sound, and may require a bit more effort to get a good sound working in the lower range.
 
The difference between small shank and large size is the size of the part of the mouthpiece that is inserted into the mouthpiece receiver. Small shank mouthpieces are the most common sold as this is what fits standard student lined instruments. Upgraded trombones and baritones may require a large shank. They are not interchangeable, but we do also sell an adaptor that works for small shanks to also play in a large shank receiver.
