Detail 01
Cup mute (not straight)
The cup over the bell rounds off the edge, so the sound is soft and covered rather than nasal and cutting.

- Pit and section players needing a covered, blended sound

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
Cork-mounted, fits inside the bell
Fit depends on your bell throat, not just the brand. Corks compress over time and can be sanded or built up.
Detail 03
Trombone-specific sizing
Not interchangeable with trumpet or euphonium mutes. Bore and bell size determine whether it seats securely.
Detail 04
Adds back-pressure
Playing muted feels stuffier than open. Intonation shifts slightly, most often in the low register.
Detail 05
Around $115
Mid-range for a cup mute. Above student plastic mutes, below multi-mute setups or adjustable-cup models.
Final check
Know before you order
- 01Test the fit on your own bell — corks vary and can slip
- 02No case or bag comes with it
- 03Check your part: some charts want straight or harmon, not cup
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my bass trombone?
It is sized for trombone bells, but bass trombone bells are typically larger. Try it on your own horn before committing, and check that the corks seat firmly without wobbling.
02How much does a cup mute quiet the horn?
Enough to sit under a section and to be less disruptive at home, but it is not a practice mute. Expect a softened, covered tone rather than near-silence.
03Does it affect intonation?
Yes, slightly. Muted playing adds resistance and can pull certain notes, most noticeably low ones. Adjust with the slide as you would with any mute.
04Cup mute or straight mute for big band?
Depends on the chart. Straight is bright and cutting, cup is soft and blended. Most big band books call for both, so many players own each.
