Thank you for viewing! Trumpet Wah-Wah Mute Material: Aluminum Is it a HARMON? A mystery. Purchased online, the product name was HARMON, but there's no label on the mute itself, so I'm not sure if it's genuine. I've been using it as is. It works fine. I've taken good care of it, but there are fine scratches overall. No dents. Please check the photos for the condition and only purchase if you understand. Thank you.
