Denis WickDW5509 Bass Trombone Straight Mute
Independent shopping perspective
The Korena take
A straight mute sized for bass trombone. For the player who needs the standard orchestral or big-band mute and has a large bass bell.
Strong match
Who this is for
- Orchestral players covering scores marked con sordino
- Big band books that call for a straight mute
- Bass trombonists who own a tenor mute that falls through the bell
Consider the trade-offs
When to look elsewhere
- Tenor trombone players — the bell taper is too large
- Anyone needing cup, harmon or bucket colors
- Players wanting a quiet practice mute for apartments
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
Bass trombone sizing
Corked for the wider bass bell throat. A tenor mute in the same shape will seat too deep or drop through.
Detail 03
Cork-seated fit
Corks hold it in the bell by friction, so seating depth is adjustable and affects both pitch and how much sound escapes.
Detail 04
Denis Wick DW5509
The bass trombone entry in Wick's straight mute line, so it sits alongside their tenor and euphonium models in the same voicing.
Final check
Know before you order
- 01Mutes raise pitch — expect to pull the tuning slide out while muted
- 02No bag or case included; store it where the corks won't get crushed
- 03Check your bell diameter first — bass bells vary and fit is by cork, not thread
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my tenor trombone?
No. It's built for the larger bass trombone bell. On a tenor it will sit too far in or won't seat correctly, which throws off both pitch and response.
02Does it make the horn quieter for practice?
Not really. A straight mute changes tone color more than volume. If you need to practice silently, you want a practice mute instead.
03Will I play sharp with it in?
Usually yes. Straight mutes push pitch up, more in the low register. Pull the tuning slide and adjust with your ear.
04Do the corks need adjusting?
Sometimes. If it seats too deep or rattles loose, corks can be sanded down or built up. That's normal fitting work, not a defect.
