Independent shopping perspective
The SM7738 is an adjustable fiber cup mute for tenor trombone with a 6.6-ounce build and neoprene composite corks to keep it in place. Its adjustable cup settings give players a way to alter the setup when matching other cup mutes in a section, while the design is intended to remain in tune across the full register. Remove the cup section and it can also cover straight-mute duties, making it useful where one mute needs to handle both roles.
