Independent shopping perspective
The Korena take
Gold-plated Schilke 47C4 trombone mouthpiece, .988-inch cup with a wide semi-flat rim, small shank. For players who already know the 47 fits them.
Strong match
Who this is for
- Tenor trombones with a small-shank receiver
- Long sets where a wider rim eases lip fatigue
- Players on a 47 who want more rim contact
Consider the trade-offs
When to look elsewhere
- Large-shank tenor or bass trombone receivers
- Lead players who need a shallow, bright cup
- Anyone still testing sizes — plating adds cost, not dimensions
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 semi-flat rim
Flatter and wider than the standard 47 rim. Spreads pressure over more lip, so endurance improves and flexibility drops slightly.
Detail 03
15/64 throat
Schilke's standard bore. Resistance stays moderate, so response is quick rather than wide open.
Detail 04
Small shank
Seats in small and medium-bore tenor slides. It will not fit a large-shank receiver.
Detail 05
Gold plating
Surface finish only. Cup, rim and throat are the same 47C4 dimensions as the plain version.
Final check
Know before you order
- 01Check your slide receiver — small shank only, and no adapter is included
- 02Rim is wider than the standard 47; expect a short adjustment period
- 03Sold as a single mouthpiece — no pouch, brush or case
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my large-bore trombone?
Only if the receiver is small shank. Many large-bore tenors take a large shank, so check the slide before ordering. No adapter is included.
02What's the difference between the 47 and the 47C4?
Cup diameter is nearly identical — .984 versus .988 inch. The C4 adds a wider, semi-flat number 4 rim for more lip support and endurance.
03Does the gold plating change how it plays?
The dimensions are identical to the standard 47C4: .988-inch cup, 15/64 throat, number 4 rim. Plating is the finish, not the playing size.
04Is this suitable for bass trombone?
No. It's a small-shank tenor size at .988 inch. Bass trombone players need a considerably larger cup diameter and a large-shank receiver.
