Denis WickDW4880 Classic Series Trombone Mouthpiece in Gold 1AL
1/8
Independent shopping perspective
The Korena take
Large-shank trombone mouthpiece with a 27.11mm cup and open backbore. Bass-trombone sized, for players who want a rich low end that stays open up top.
Strong match
Who this is for
- Bass trombone in orchestra, wind ensemble or brass band
- Large-bore tenor players who want a darker, wider sound
- Tenor doublers needing one dedicated large mouthpiece for bass parts
Consider the trade-offs
When to look elsewhere
- Small-bore tenor trombones — the large shank will not seat
- Lead and jazz playing; the shallower 12CS suits that better
- Developing players who cannot yet fill a 27mm cup
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
27.11mm cup diameter
Near the top of the range, just under the 0AL and 00AL. More lip vibrates, so the low register opens up and air demand rises.
Detail 03
6.09mm rim width
Narrow for a cup this wide. Better flexibility and slotting, less cushion across a long rehearsal.
Detail 04
7.45mm throat
Wide bore passes air freely. Bigger sound and less resistance, but soft dynamics take more control.
Detail 05
Open backbore
Spreads and warms the tone instead of focusing it. Combined with the wide throat it favors volume over edge.
Detail 06
Gold plating
Slicker and warmer against the lip than silver, and it does not tarnish. Common choice if silver irritates your skin.
Final check
Know before you order
- 01Check your receiver — large shank only, no small-bore tenor
- 02Plan a few weeks of adjustment before endurance returns on a cup this size
- 03Gold is a plating; it wears thin at contact points over years of play
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 1AL a bass trombone mouthpiece?
The 27.11mm cup and large shank put it in bass trombone territory. Large-bore tenor players also use it when they want a darker, wider sound with more low-register weight.
02How does the 1AL compare to the 2AL?
The 2AL is slightly smaller at 27mm with a wider 6.73mm rim and a barrel backbore, giving a more focused traditional bass sound. The 1AL is more open in all registers.
03Will it fit my large-bore tenor trombone?
Yes, if the receiver takes a large shank. Most large-bore tenors do. Small-bore horns will not accept it — those take the small-shank versions.
04Does gold plating change the sound?
Plating affects feel and grip far more than tone. Gold is smoother and warmer to the touch than silver and will not tarnish. The cup, throat and backbore drive the sound.
