Independent shopping perspective
The Korena take
Schilke's lead trumpet mouthpiece in gold plate: .660 inch rim, shallow A cup, semi-flat 4 rim and tight backbore. For players working above the staff.
Strong match
Who this is for
- Lead trumpet in big band and show pits
- Commercial and horn-section work that sits high
- Players whose lip reacts badly to silver plating
Consider the trade-offs
When to look elsewhere
- Orchestral and legit playing needing cup depth and warmth
- Developing players, who are better served by the standard 13
- Anyone wanting a free-blowing feel; the 13A4 is more open
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
Shallow A cup
Less volume to fill means less air and a more direct sound, with the top of the range easier to hold.
Detail 03
Tight a-backbore
Adds resistance behind the throat. The 13A4 is the same mouthpiece with a standard c-backbore if this feels stuffy.
Detail 04
Number 4 semi-flat rim
Wider, flatter contact spreads pressure across more of the lip, which is what buys endurance on long sets.
Detail 05
27 throat
Smaller than the 26 throat on the standard 13. More back-pressure and firmer slotting, with less air moving through.
Detail 06
Gold plating
Slicker feel than silver on the lip, and an option if silver leaves your skin irritated.
Final check
Know before you order
- 01Gold plate is soft; skip abrasive polish and store it in a pouch
- 02A shallow cup changes pitch tendencies, so recheck tuning with the section
- 03Keep a deeper cup on hand if you also play legit dates
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this a lead mouthpiece?
Yes. The shallow A cup, semi-flat number 4 rim and tight a-backbore together are built for upper-register playing without giving up tone production.
02What is the difference between the 13A4a and the 13A4?
Only the backbore. The 13A4 uses a standard c-backbore, which blows more openly. The 13A4a uses the tight a-backbore for more resistance.
03How does it compare to the 14A4a?
Same shallow cup, 4 rim and tight backbore, but the 14A4a is wider at .673 inch versus .660 inch. Pick by the rim width you play.
04Does gold plating change how it plays?
The feel changes, not the response. Cup depth, rim shape, throat and backbore set how it plays. Gold is about comfort and skin sensitivity.
