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
The smallest in this range. Less lip inside the cup means easier high notes but a smaller low register.
Detail 02
The tightest throat in the series. More back-pressure, more resistance to lean on, and a more compact sound.
Detail 03
Narrows the air path behind the throat, focusing the tone rather than letting it spread. Adds projection over an open backbore.
Detail 04
Moderate contact area. Enough support for endurance without the pillowy feel that dulls articulation.
Detail 05
Slightly grippier on the lip than gold and harder wearing than raw brass. Some players react to silver against skin.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Same 16mm cup and 5.3mm rim. The 5B has a tighter 3.97mm throat and a V backbore, so it's more focused and projects harder than the warmer, open-backbore 5.
No. This is a cornet mouthpiece with a cornet shank. It won't seat properly in a trumpet receiver.
The small 16mm cup and tight throat help the upper register. The trade-off is a thinner low range compared with the larger 2 or 3.
The V backbore and focused sound are built to project through a section, which is what brass band cornet parts usually ask for.
