Detail 01
17.50mm cup diameter
The widest in this range. More lip vibrates, so the sound gets bigger and darker, and the high register gets harder.

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 widest in this range. More lip vibrates, so the sound gets bigger and darker, and the high register gets harder.
Detail 02
Extra wide, so pressure spreads across more lip. Helps on long sessions, feels slightly less precise on fast articulation.
Detail 03
Wide bore that lets air move freely for volume, but it feels loose if you are not pushing enough air.
Detail 04
Keeps resistance even through the register and holds the sound together at high volume rather than letting it spread.
Detail 05
Modeled on a 19th-century large-bore design, which is why cup and rim run larger than most modern trumpet mouthpieces.
Detail 06
Smoother on the lip than silver and slower to wear through. It does not change cup, rim or throat dimensions.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
If you already play a Denis Wick 1 or 1C comfortably, the step to 17.50mm is small. Coming from a 3 or 4, expect the upper register to take real work.
The 1C is 17.25mm with a 5mm rim, built to play easier and more flexibly with better upper-register focus. The 1X is wider in cup and rim, aimed at symphonic size and comfort.
Only indirectly. Gold feels smoother and warmer than silver, so the rim grabs less. The 5.23mm rim width does far more for comfort than the plating does.
Yes, it uses the standard trumpet shank found on Bb, C, D and Eb trumpets. Cornet and flugelhorn use different shanks and will not take it.
