Detail 01

Denis WickDW5880 Classic Series Trombone Mouthpiece in Silver 9BS
1/2
Independent shopping perspective
The Korena take
A small shank trombone mouthpiece with a moderate 25mm cup and V-type backbore. A general-purpose choice that leans toward the upper register.
Strong match
Who this is for
- Small bore tenor trombone players wanting one do-everything mouthpiece
- Lead book work where the range sits high
- Alto trombone players needing a mouthpiece that fits properly
Consider the trade-offs
When to look elsewhere
- Large bore or bass trombones — the shank won't fit
- Players chasing a big, dark orchestral low register
- Anyone already happy on a wider rim; 25mm is on the narrow side
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
The narrower end of the range. Less lip inside the cup means easier high notes but a smaller, less open low register.
Detail 03
6.46mm rim width
A middle-width rim. Enough surface for endurance on long sets without deadening the flexibility you need for fast intervals.
Detail 04
6.66mm throat
A moderate opening. Adds a little resistance you can push against, which helps control and keeps the top end from spreading.
Detail 05
V-type backbore
The taper past the throat opens gradually, giving a brighter, more focused sound with clear projection over an ensemble.
Detail 06
Silver plate
Standard plating with slight grip against the lip. Some players react to silver; gold plate is the usual alternative.
Final check
Know before you order
- 01Check your horn's receiver — small shank only, not large bore
- 02Mouthpiece only; no pouch, case, or cleaning brush included
- 03Expect a week or two of adjustment before judging the fit
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 — typical of small bore tenors and altos. Large bore tenors and bass trombones need a large shank mouthpiece.
02How does 9BS compare to a 6BS?
The 9BS has a slightly smaller 25mm cup versus 25.30mm, and a wider rim at 6.46mm. Same throat and V backbore, so it favors the high register a little more.
03Is this good for jazz?
Yes. The narrow cup and V backbore suit lead playing, with a bright focused sound that cuts through a section.
04Can I use it on alto trombone?
Yes. It's a common choice for alto, where the smaller cup matches the horn's higher range.
