Detail 01
It's a top, not a whole mouthpiece
The cup and rim only. It threads onto a separate backbore that you buy or already own.

Independent shopping perspective
A gold-plated top for the Warburton two-piece trumpet and cornet mouthpiece system, in Size 3. For players already committed to that modular setup.

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 cup and rim only. It threads onto a separate backbore that you buy or already own.
Detail 02
Slicker on the lip than silver and less likely to cause a reaction in players sensitive to nickel.
Detail 03
Fixes the rim and cup dimensions. Changing size later means only a new top, not a whole mouthpiece.
Detail 04
Same top works on both horns once paired with the correct backbore for each instrument.
Detail 05
You can swap backbores to change resistance and blow while keeping the exact rim feel you've built up.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is the top half only. It screws into a Warburton backbore, which is sold separately and is required to play.
Not meaningfully. The difference is at the lip — gold feels slicker and warmer than silver. Cup and rim dimensions drive the sound.
Yes, paired with a cornet backbore. The top is the same; the backbore is what matches the instrument.
You buy a different top and keep the backbore. That's the point of the two-piece design — you swap one half instead of starting over.
