This is a wah-wah mute for trombone. It's the mute made famous by Miles Davis. It's the super classic Harmon mute. It has a good balance of operability and sound. There is peeling of the cork, peeling of the sticker, dents in the body, and scratches. It shows signs of use, but there are no major scratches or dents that would interfere with playing. Please refrain from comments asking for a price reduction. If you are interested in used mouthpieces or new mouthpieces, please search for Net Brass. net-brass.com #mute #trombone
