Detail 01
17.25mm cup diameter
One of the widest in the line. More lip vibrates, giving fuller low and mid range but demanding more endurance.

Independent shopping perspective
Silver-plated trumpet mouthpiece with a thicker outer wall than a standard Denis Wick. The 1C is a large cup for players who want volume and low-register weight.

Strong match

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
One of the widest in the line. More lip vibrates, giving fuller low and mid range but demanding more endurance.
Detail 02
Wider than the 3.70mm sizes. Air moves more freely for volume, at the cost of some back-pressure to lean on.
Detail 03
Narrow to medium. Flexible and slur-friendly, but less cushion than the 5.75mm 4X rim over long sessions.
Detail 04
Extra mass around the cup. Notes center more firmly and the sound stays compact when pushed hard.
Detail 05
Even taper rather than a V. Keeps the tone rounded and centered across registers instead of biasing brightness.
Detail 06
Standard finish, slightly grippier than gold under the lip. Wears through with heavy use over years.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
The added mass at the cup and rim resists vibration loss. Notes lock in more firmly and the core of the sound holds together at higher volume.
The 1C is 17.25mm with a 3.90mm throat; the 1 1/2C is 17mm with a 3.80mm throat and a slightly wider rim for more stability and comfort.
No. The large cup and open throat favor volume and fullness. The 4X, with its smaller 16.50mm cup and V backbore, is built for the high register.
No. This is a trumpet mouthpiece with a trumpet shank. Cornets use a different, shorter shank.
