Independent shopping perspective
The Korena take
Gold-plated Schilke 15C4: a .675-inch cup with a semi-flat rim, aimed at players who need endurance through long sessions and want a smoother rim feel.
Strong match
Who this is for
- Long rehearsals and pit work where rim fatigue ends the night early
- Model 15 players who want more comfort without changing cup size
- Players whose lips react badly to silver plating
Consider the trade-offs
When to look elsewhere
- Players who need a bigger rim; .675 inch runs small
- Upper-register specialists better served by the shallow A-cup models
- Anyone buying a spare horn mouthpiece at this price
What matters in use
The specifications, translated
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 02
Number 4 semi-flat rim
Wider, flatter contact area spreads pressure across the lip, so fatigue arrives later in the day.
Detail 03
26 throat
The bore size used across most of this series, so response and resistance stay consistent if you switch models.
Detail 04
Same dimensions as the model 15
You keep the free-blowing, clear character of the 15. The rim shape is the only real change.
Detail 05
Gold plating
Slicker and softer under the lip than silver, and an option if silver plating irritates your skin.
Final check
Know before you order
- 01Ships as the mouthpiece alone; budget for a pouch if you carry it loose
- 02Trumpet shank only — it will not seat in a cornet or flugelhorn
- 03Give a new rim shape two weeks before judging it; endurance dips first
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does 15C4 actually mean?
15 is the rim size, .675 inch. C is the cup. 4 is the rim contour — the semi-flat shape Schilke uses for endurance rather than the rounder profiles.
02Is the gold worth it over the silver 15C4?
Cup, rim and throat are identical. Gold feels slicker on the lip and suits players who react to silver. If neither matters to you, the silver plays the same for far less.
03Will this help my high register?
Not directly. It is built around rim comfort and endurance. The shallow A-cup models with the tighter backbore, like the 15A4a, are the ones aimed at upper-register work.
04Will it fit my trumpet?
Yes, any standard Bb or C trumpet receiver. It will not fit a cornet or flugelhorn, which take different shanks.
