Detail 01
Medium-deep cup
Keeps the covered flugel color but stops short of a full deep cup, so high notes take less air and effort.

Denis WickDW4884 Classic Series Flugelhorn Mouthpiece in Gold 4BFL
1/2
Independent shopping perspective
The Korena take
Gold-plated flugelhorn mouthpiece, medium-deep cup, 16.50mm rim. A middle-ground size for players who want flugel warmth without giving up the top end.
Strong match
Who this is for
- Doublers moving between trumpet and flugel who need a familiar mid-size rim
- Players who find deep flugel cups too heavy in the upper register
- Anyone who reacts to silver plating and needs gold
Consider the trade-offs
When to look elsewhere
- Horns with a medium European shank receiver
- Players chasing the darkest possible flugel sound
- Trumpet or cornet use — wrong shank and wrong cup
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
16.50mm cup diameter
Mid-size rim in this range. A common landing spot for players who find 16mm cramped and 17mm tiring.
Detail 03
5.13mm rim width
Moderate width. Enough cushion for endurance without the pinned-down feel of the widest rims.
Detail 04
4.60mm throat
The standard throat across most of this range. Freer air flow and more volume ceiling than the 4.50mm option.
Detail 05
Open backbore
Lets the tone spread after the throat. Bigger, less focused sound than a V-type backbore would give.
Detail 06
Standard USA shank
Fits horns built to the American receiver taper. It will not seat properly in a medium European receiver.
Final check
Know before you order
- 01Confirm your flugelhorn uses a standard USA shank before ordering this version
- 02Sold as the mouthpiece alone, no pouch or case
- 03Expect a settling-in period before your sound and range stabilize
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does 4BFL compare to 4FL?
Same 16.50mm diameter and 5.13mm rim. The 4BFL cup is medium-deep, the 4FL is deep. Pick 4BFL for easier high range, 4FL for a darker sound.
02Is 16.50mm a good starting size?
It sits mid-range here, between the 16mm and 17mm options. That makes it a reasonable first try if you don't already know your preferred diameter.
03Will this work with a European flugelhorn?
Not if the horn takes a medium European shank. This size is cut with a standard USA shank. Check your receiver first.
04Does gold plating change the sound?
No meaningful tonal difference. It matters for lip comfort and for players who react to silver, and it feels slightly slicker on the rim.
