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
Brighter and more cutting than fiber or copper-bottom mutes. Projects through an orchestral texture.
Detail 02
The interior lining damps overtones so the mute sounds focused rather than harsh or buzzy.
Detail 03
Sits inside the bell on cork strips. Adds resistance and typically pushes pitch slightly sharp.
Detail 04
Voiced for orchestral and concert work rather than jazz lead playing.
Detail 05
Corks compress and wear over time. Loose corks cause rattles and let the mute drop out mid-phrase.

Product questions
Straight answers to the questions shoppers most often ask about this product.
It is a straight mute, not a practice mute. It changes tone color and adds a bright edge. Volume drops only somewhat.
Aluminum gives a brighter, more cutting sound with more projection. Fiber mutes are darker and warmer.
Straight mutes generally raise pitch by adding resistance. Pull your tuning slide slightly and check with a tuner while muted.
It is built for standard tenor trombone bells. Bell sizes vary, so check the cork fit — corks can be sanded down or replaced if tight.
