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
Metal is denser and thinner-walled than hard rubber, giving a brighter, more projecting sound with more edge.
Detail 02
Moderately open. Takes more air than a stock piece but stays controllable; pairs well with softer reeds.
Detail 03
Sized for an alto neck cork only. It will not seat on a tenor, soprano or bari neck.
Detail 04
Sits differently on the cork than rubber, so tuning position and cork thickness usually need adjusting.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is the tip opening — the gap between reed tip and mouthpiece tip. 5* is a moderate opening, more open than most stock mouthpieces but not extreme.
Probably not. Metal mouthpieces have a narrower profile than hard rubber, so a rubber-sized ligature usually will not clamp properly. Use a ligature made for metal.
With a 5* opening, most players land around 2.5 to 3. If you use a 3.5 on a stock mouthpiece, try a 3 here.
It projects more and sounds brighter, with more edge at volume. Whether it feels louder depends as much on the tip opening and your air as the material.
