Detail 01
A cup (shallow)
Less cup volume means faster response and an easier upper register, paid for in low-register depth and warmth.

Independent shopping perspective
The Korena take
Silver-plated Schilke lead mouthpiece: shallow A cup, semi-flat number 4 rim, tight backbore. Built for players who live above the staff and need the endurance for it.
Strong match
Who this is for
- Lead and commercial playing where the top of the range matters
- Loud sections where a cushion rim saves your chops
- Players moving off a stock piece to a dedicated high-register setup
Consider the trade-offs
When to look elsewhere
- Symphonic and legit work, where a deeper B or C cup fits
- Developing students — a shallow cup makes low notes and intonation harder
- Anyone chasing a dark, broad sound; this leans bright and compact
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 rim
Semi-flat with a cushion feel. Spreads pressure so long, loud sets cost less endurance than a rounded rim would.
Detail 03
Lowercase a-backbore (tight)
Narrower bore behind the throat adds resistance. Notes lock in faster up high and the sound stays focused.
Detail 04
Group I sizing
Schilke's narrower band of cup diameters. Group II numbers run wider, so switching between groups is a real change in feel.
Detail 05
The 14A4a stamp
Number is cup diameter, letter is cup depth, second number is rim contour, trailing lowercase letter is the backbore.
Detail 06
Silver plating
The standard finish. Slightly more grip on the lip than gold, and a polish cloth brings back tarnish.
Final check
Know before you order
- 01Mouthpiece only — no pouch, brush or case in the box
- 02A shallow cup shifts intonation; expect a few sessions of adjustment
- 03Rinse and wipe it regularly; plating wears at the rim under heavy daily use
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 14A4a good for lead playing?
That is what the combination is built for. Shallow A cup, tight a-backbore and semi-flat 4 rim favor range and endurance over a broad, dark tone.
02What do the letters and numbers mean?
14 is the cup diameter, A the shallow cup depth, 4 the semi-flat rim contour, and the lowercase a the tight backbore that adds resistance up high.
03How is this different from a 13A4?
The 13A4 sits slightly narrower and uses the standard c-backbore, so it blows freer. The 14A4a is wider with more resistance behind the throat.
04Will it fit any trumpet?
Yes — standard trumpet shank, so it seats in any normal trumpet receiver. Cornet and flugelhorn need their own shanks.
