Held by friction alone, not clips. Fit varies with bell taper, so seating depth differs between horns.

Mid-range for a stem mute. Above stamped student mutes, below custom hand-spun models.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is sized for Bb trumpet bells. A flugelhorn's wider, faster bell taper will not seat it correctly.
Yes. Stem out is the standard jazz setting and gives the thin, buzzy, distant tone. Stem in produces a fuller sound.
It reduces volume noticeably, but it is a performance mute, not a practice mute. A dedicated practice mute is far quieter.
It is held by cork friction. A properly seated mute stays put, but the cork can loosen with use and may need replacing.
