What matters in use
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 01
Seats in a trumpet bell only. Bell throat differences on cornet and flugelhorn make it unusable there.
Detail 02
Friction fit on corks. Corks compress over time, changing how deep it seats and how the horn plays.
Detail 03
Mid-tier for a trumpet mute — above student-spare pricing, below pro specialty mutes.
Detail 04
A dedicated mute maker rather than a general accessory brand, so sizing is built around brass bells.
Detail 05
Nothing to assemble or adjust. It goes in the bell and comes out; there are no moving parts to fail.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Not really. It's a performance mute for tone color. Volume drops some, but not enough for an apartment at night.
It's built for trumpet. A cornet's bell taper differs, so it can wedge too deep or rattle loose.
Build up the corks with cork tape or replace them. Depth is set by cork thickness, and that's adjustable.
Yes. Anything in the bell alters pitch, usually slightly sharp. Tune with the mute in for muted passages.
