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 02
Chamber and shank are cut for an alto neck. It will not seat correctly on a soprano or tenor.
Detail 03
Opening up usually means dropping reed strength. Expect to retest half a step softer than what you play now.
Detail 04
Reeds and ligature are separate. Your current ligature may not clamp this body correctly.
Detail 05
Step-up money rather than student money. Budget for reeds and possibly a ligature on top of it.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, it's cut for alto necks. It won't fit soprano, tenor or baritone.
Probably worth testing. A different tip opening changes how a given strength feels, and many players end up half a strength away from where they started.
Plan on supplying your own. Check that it clamps this mouthpiece properly before you count on it.
It's a deliberate facing rather than whatever shipped in the case, so you get a defined tip opening to build reed choice around. Expect an adjustment period.
