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
Mid-size rim. Broad enough to give the tone room, small enough to control — a common landing spot for adult players.
Detail 02
Shallower than the standard model 14 cup. Brightens the sound and supports the upper register; you give up some low-register depth.
Detail 03
Standard drill. Holds back enough air to keep the shallow cup feeling stable when you push volume.
Detail 04
Cornet receivers are not trumpet receivers. This is dedicated to cornet — buy the trumpet equivalent separately if you play both.
Detail 05
Slicker on the lip than silver, and the standard option if silver or nickel irritates your skin.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is built with a cornet shank, which is shorter and narrower than a trumpet's. Use a trumpet mouthpiece on trumpet.
Same .670-inch cup diameter, so the rim feels the same. The B cup is medium-small and shallower than the 14's standard cup, which brightens the sound.
It trades some warmth for brilliance and range. If you want the big round cornet tone, look at the funnel-shaped E cups like the 11E or 8E2 instead.
Gold feels slicker and warmer on the lip and avoids the skin reaction some players get from silver. It does not change the cup, rim or throat dimensions.
