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
Tenor trombone sizing
Cut for a tenor bell throat. On a bass or large-bore bell it will seat wrong or not at all.
Detail 03
Sits in the bell on corks
Cork contact sets depth and pitch. Worn or compressed corks shift intonation and let the mute slip.
Detail 04
$95.99
Sits above student mutes. The step up buys steadier intonation and a more even response across the range.
Detail 05
Cup gap
How close the cup sits to the bell changes darkness. Tighter is duller, wider lets more of the horn through.
Final check
Know before you order
- 01Check your bell diameter and bore before ordering — tenor sizing is not universal
- 02No case or bag; budget a slot in your gig bag
- 03Expect to re-learn intonation in the low register with it in
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my bass trombone?
No. It is made for tenor trombone bells. A bass bell is larger and the mute will not seat correctly.
02How much does it quiet the horn?
A cup mute changes tone more than volume. It darkens and covers the sound, but it is not a practice mute.
03Does it push the pitch sharp?
Most mutes shift intonation somewhat, usually sharp. Adjust with the slide and check tuning with the mute in.
04Can I adjust the cup depth?
Adjustable-cup designs let you move the cup closer or further from the bell to change how dark it sounds. Check the mute before relying on it.
