Detail 01
16.50mm cup diameter
Narrower than the 1 and 3 sizes in this line. Less lip inside the cup, which favors the upper register over low-register breadth.

Independent shopping perspective
Silver-plated trumpet mouthpiece with a heavier outer mass. The 4X pairs a shallow, bright cup with a wide rim for endurance.

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
Narrower than the 1 and 3 sizes in this line. Less lip inside the cup, which favors the upper register over low-register breadth.
Detail 02
The widest rim in this series. Spreads pressure over more lip area, so endurance improves but fine flexibility can feel slightly damped.
Detail 03
A moderately tight throat. Adds some resistance you can push against, which helps articulation and slotting up high.
Detail 04
Unlike the barrel backbores elsewhere in this line, the V shape brightens the sound and sharpens projection.
Detail 05
Extra metal around the cup steadies the note center and firms up the attack. Slightly less response to subtle color changes.
Detail 06
Slicker and slightly brighter than gold plate, and it holds up to daily use. Some players react to the nickel underneath.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
In this line, X models pair a wider rim with a V-type backbore. That combination targets comfort and a brilliant, free-blowing high register.
Yes. Added mass at the cup makes note centers feel more locked in and attacks firmer. Some players find it less responsive to subtle dynamic shading.
It leans commercial and lead. The shallow cup, tight throat, and V backbore favor brightness and projection over the broad sound most orchestral playing wants.
Wipe it dry after playing and store it out of open air. Rinse it in warm water weekly. Silver polish works, but frequent polishing thins the plating over time.
