Denis WickDW4880 Classic Series Trombone Mouthpiece in Gold 9BL
1/2
Independent shopping perspective
The Korena take
Gold-plated large-shank trombone mouthpiece, 25mm cup with a V-type backbore. For large-bore players who want an easier, brighter top register.
Strong match
Who this is for
- Lead and commercial work on a large-bore tenor
- Players whose high register fades on deep orchestral cups
- Doublers wanting one bright large-shank piece for both horns
Consider the trade-offs
When to look elsewhere
- Small-bore trombones — the shank will not seat
- Bass trombone or symphonic section playing needing a wide cup
- Players chasing a dark, broad orchestral core
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 narrowest cup in this large-shank range. Less lip inside the cup, so high notes and endurance come easier.
Detail 03
V-type backbore
Funnel taper instead of a barrel. Adds brilliance and edge rather than the rounder, darker core of the AL models.
Detail 04
6.66mm throat
Tighter than the 7.2-7.4mm orchestral models. More resistance to lean on, less air needed to fill it out.
Detail 05
6.46mm rim width
Middle of the road. Enough contact to spread pressure without the flexibility loss of the widest rims.
Detail 06
Gold plating
Feels softer and slicker on the lips than silver. Useful if silver plating irritates your skin.
Final check
Know before you order
- 01Check your receiver first — large shank will not fit a small-bore slide
- 02Mouthpiece only; no pouch, case, or cleaning brush
- 03Give a new rim two weeks before deciding it's wrong
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only a large-shank receiver, which is standard on large-bore tenors and bass trombones. Small-bore horns need the small-shank version, the 9BS.
02What's the difference between the 9BL and 9BS?
Nothing but the shank. Both are 25mm cup, 6.46mm rim, 6.66mm throat, V-type backbore. BL is large shank, BS is small shank.
03Does gold plating sound different from silver?
It changes feel, not sound. Gold is smoother and warmer against the lips, and it's the usual choice for players who react to silver.
04Is this a good jazz or lead mouthpiece?
Yes. The small cup, tight throat, and V-type backbore give a brilliant, projecting high register, which is what lead and commercial playing asks for.
