Independent shopping perspective
The Korena take
Gold-plated Schilke 18C3 trumpet mouthpiece. Large .690" diameter for players with a developed embouchure who want a rich, brilliant tone with a big-cup feel.
Strong match
Who this is for
- Advancing players moving up from a stock 7C-size piece
- Section trumpet work where tone volume matters more than screaming range
- Players whose lips react to silver plating
Consider the trade-offs
When to look elsewhere
- Beginners still building embouchure strength on a large rim
- Lead players who need a shallow cup for high register
- Anyone wanting a cheap backup piece to leave in a case
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
High point nearer the center
Makes the 18 feel smaller than .690" suggests, so the jump from a medium piece is less jarring.
Detail 03
C cup
Standard depth. Full sound without the darkness of a D or E cup, and it keeps upper register workable.
Detail 04
Number 3 rim
Standard rounded contour. Good flexibility and quick response, less cushion than a semi-flat 4 rim.
Detail 05
26 throat
Schilke's standard bore. Neither restrictive nor wide open, so blowing resistance stays familiar.
Detail 06
Gold plating
Warmer, slicker feel on the lips than silver, and an option if silver causes a reaction.
Final check
Know before you order
- 01Mouthpiece only. No trumpet, case, or pouch included.
- 02Confirm your rim size first. .690" is a jump from most student pieces.
- 03Gold plating wears with use. Handle by the shank, not the rim.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 18C3 too big for a high school player?
It can be. At .690 inches it's a large diameter and rewards a developed embouchure. Players still building strength usually do better on a smaller Group I size.
02What's the difference between the 18 and the 18C3D?
Same .690 inch diameter, but the 18C3D uses a larger D backbore for a broader, darker tone. The 18C3 stays tighter and more brilliant.
03Why choose gold over silver plating?
Gold feels smoother and slightly warmer on the lips, and it's the option for players who react to silver plating. Cup and rim dimensions are identical.
04Will this fit any trumpet?
It's a standard trumpet shank, so it fits standard Bb and C trumpets. It's not a cornet or flugelhorn mouthpiece.
