Denis WickDW5281U Ultra Series Cornet Mouthpiece in Silver 1.25C
Independent shopping perspective
The Korena take
The silver Ultra 1.25C is a cornet mouthpiece with a 17 mm cup diameter, 3.80 mm throat, and V-type backbore. It carries the Ultra series’ brighter, focused cornet sound and a slightly more rounded rim contour intended to support flexibility and stamina. For players using a Denis Wick Ultra trumpet mouthpiece, the precisely matching rim makes moving between trumpet and cornet a more consistent physical transition.
Strong match
Who this is for
- Players alternating between cornet and trumpet with an Ultra trumpet mouthpiece.
- Cornet parts that need a brighter, focused sound through a microphone.
