SchilkeFlugelhorn Series Mouthpiece in Gold Gold 6F4
Independent shopping perspective
The Korena take
Gold-plated Schilke flugelhorn mouthpiece, .630 inch cup — the narrowest rim in the F series. For flugel players wanting a tighter rim than standard.
Strong match
Who this is for
- Flugel doublers coming off a small trumpet rim like the 6A4a
- Players who lose control on wider flugel rims
- Lead-oriented brass players adding flugel to the book
Consider the trade-offs
When to look elsewhere
- Trumpet or cornet — the shank is flugelhorn-specific
- Players who want a broad, open low register
- Anyone already comfortable on a 16F4 or 17F rim
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
24 throat
Every F model shares it, so moving up or down the line changes rim size, not the blowing resistance.
Detail 03
Compares to a 6A4a rim
If you already play a 6A4a on trumpet, the rim contact will feel familiar when you switch to flugel.
Detail 04
Gold finish
Plating choice only. Cup diameter, throat and rim shape match the silver version of the same model.
Detail 05
Flugelhorn shank
Cut for a flugelhorn receiver. It will not seat in a trumpet or cornet leadpipe.
Final check
Know before you order
- 01Confirm your flugelhorn's receiver takes this shank before ordering
- 02Mouthpiece only — budget for a pouch if you carry it loose
- 03Keep your current piece; a smaller rim takes weeks to settle
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trumpet?
No. It is a flugelhorn mouthpiece and the shank is cut for a flugelhorn receiver. For trumpet, look at Schilke's trumpet line instead.
02Is the gold different from the silver besides looks?
The playing dimensions are the same. Cup diameter is .630 inch and the throat is 24 either way. The difference is the plating on the surface.
03How does the 6F4 compare to the 15F or 17F?
It is the smallest rim of the group at .630 inch, against .674 for the 15F and .682 for the 17F. Throat size is 24 on all three.
04Does it come with a case?
Plan on the mouthpiece by itself. If it rides loose in a gig bag, add a pouch so the rim and shank do not get dinged.
