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
Cut for the wider bass bell and larger bore. A tenor mute would sit too deep and choke the pitch.
Detail 03
Cork mounting
Corks hold the mute in the bell and set how deep it sits, which affects both intonation and how much sound is blocked.
Detail 04
Stonelined Series
The Humes & Berg line most often named in parts when an arranger specifies a mute brand.
Detail 05
Under $40
Entry-level pricing for a standard mute type, so it works as a school or first-mute purchase.
Final check
Know before you order
- 01Straight mutes push pitch sharp; expect to adjust your slide and tuning
- 02Corks can compress over time and need sanding or replacement
- 03No case or bag included — mutes dent easily in a gig bag
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 is sized for bass trombone. In a smaller tenor bell it would sit too deep and affect pitch and response.
02Why does my playing go sharp with the mute in?
Straight mutes raise pitch by restricting the bell. Tune with the mute in and adjust your slide positions accordingly.
03What does con sordino mean in my part?
It means play muted. Unless another mute is named, a straight mute is the standard choice.
04How do I stop the mute falling out?
The corks must grip the bell. If it slips, the corks have compressed; if it sticks too deep, sand them down slightly.
