What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Mouthpiece bores and facings are sized per instrument. This seats on an alto neck only; it will not fit tenor or soprano.
Detail 02
The letter marks alto fit, the number marks the facing. Two pieces with different numbers blow and respond differently.
Detail 03
Names the facing family, not just one model. Ligature fit is judged by the shape of the piece, so match by series.
Detail 04
Tip opening changes what reed strength feels right. Switching mouthpieces usually means retesting strengths you thought you'd settled.
Detail 05
Well above a stock mouthpiece, below hand-faced custom work. What you get for the money is a known, repeatable facing.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is cut for alto. Tenor, soprano and baritone each take their own size, and the bore will not seat correctly on the wrong neck.
Confirm with the seller before ordering — mouthpieces are often sold on their own. You need both: the ligature holds the reed, the cap protects the tip.
That depends on the facing and your embouchure, not on skill level alone. Buy a couple of strengths around what you play now and test them.
If the stock piece feels stuffy or hard to control, yes. If you are a few months in, spend on lessons and decent reeds first.
