Denis WickDW5880 Classic Series Trombone Mouthpiece in Silver 12CS
1/2
Independent shopping perspective
The Korena take
Small-shank trombone mouthpiece with a narrow 24.50mm cup and wide rim. Built for jazz and lead players on small-bore horns who need high-register endurance.
Strong match
Who this is for
- Small-bore tenor trombone in jazz and big-band sections
- Lead playing where the high register has to stay clear
- Long sets where rim comfort decides how long you last
Consider the trade-offs
When to look elsewhere
- Large-bore tenor and bass trombones — the shank won't seat
- Orchestral players wanting a broad, dark symphonic sound
- Beginners still building an embouchure; the small cup is unforgiving
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
24.50mm cup diameter
The narrowest cup here. Less lip inside the rim, so high notes come easier and lows thin out.
Detail 03
6.71mm rim width
Wide rim spreads pressure across more lip, which is what holds endurance together on long gigs.
Detail 04
6.10mm throat
Tight throat. Gives you resistance to push against and brightens the sound as volume climbs.
Detail 05
V-type backbore
Funnel taper rather than a stepped one, which is where the resonant, ringing top end comes from.
Detail 06
Silver plating
Wears slowly and cleans up with soap and water. Tarnish is cosmetic and wipes back off.
Final check
Know before you order
- 01Mouthpiece only — no pouch, case, or cleaning brush included.
- 02Check your slide receiver: small shank is visibly narrower than large shank.
- 03Coming off a deeper cup, expect the low register to feel tight initially.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
It's a small shank, so it fits small-bore tenor trombones. Large-bore tenors and bass trombones take a large-shank mouthpiece instead.
02Is the 12CS good for jazz?
Yes, it's the jazz model in this series. The small cup, tight 6.10mm throat and V backbore favor a bright, projecting lead sound.
03How does 12CS compare to 6BS?
6BS is larger overall: 25.30mm cup, narrower 6.26mm rim, wider 6.66mm throat, and reads as a general-purpose piece. 12CS is smaller with a wider rim for endurance up high.
04Does the silver finish tarnish?
Yes, silver plate darkens with skin contact and air. Wipe it after playing and wash it periodically in warm soapy water. Tarnish affects looks, not playability.
