Detail 01
Small shank
Fits small-bore tenor and alto trombones. It will not go into a large-shank slide, and no adapter fixes that cleanly.

Denis WickDW4880 Classic Series Trombone Mouthpiece in Gold 9BS
1/2
Independent shopping perspective
The Korena take
Small-shank trombone mouthpiece, 25mm cup with a V-type backbore, in gold finish. An all-around small-bore piece that leans toward lead work and alto trombone.
Strong match
Who this is for
- Small-bore tenor players who need one mouthpiece for everything
- Lead book playing where the top of the range gets used
- Doublers who also pick up alto trombone
Consider the trade-offs
When to look elsewhere
- Large-bore and bass trombone players — the small shank will not seat
- Players chasing a wide, dark orchestral low register
- Beginners who just need something that works; the stock piece costs far less
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
25mm cup diameter
On the narrow side for tenor. Less lip inside the cup means easier high notes and less fatigue over a long set.
Detail 03
6.46mm rim width
A medium rim. Wide enough to spread pressure across the lip without deadening the feel of an attack.
Detail 04
6.66mm throat
Moderately tight. Adds resistance you can push against, which helps the top of the range stay centered.
Detail 05
V-type backbore
Shapes the air after the throat so the high register stays brilliant and full rather than going thin.
Detail 06
Gold finish
Changes how the rim feels against the lip and how the surface wears. Cup, rim and throat dimensions are unaffected.
Final check
Know before you order
- 01Check your slide receiver first — small shank and large shank are not interchangeable
- 02Sold as the mouthpiece alone; no pouch, case or cleaning brush
- 03A rim change takes a couple of weeks to settle, so don't judge it on day one
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only if it takes a small shank, which most student and small-bore tenor horns do. Large-bore tenors and bass trombones need the large-shank version instead.
02What is the difference between the 9BS and the 9BL?
The cup diameter, rim width, throat and backbore are the same. The BS is small shank and the BL is large shank, so pick by your slide receiver.
03Is this a good jazz mouthpiece?
It handles lead and upper-register playing well. If you want a wider, rounder rim built for endurance, the 12CS is the model aimed at jazz.
04Does the gold plating change the sound?
No. Cup diameter, rim width and throat are what shape the sound, and those are unchanged. The finish affects grip against the lip and how the surface wears.
