Trumpet Harmon Mute HARMON Harmon / Trumpet WAH WAH Mute Aluminum Purchased May 2021 Used a few times in performances. My assessment is as follows: The cork is in good condition and has never fallen out. The sound is good, and I think it can still be used◎ I am also selling a straight mute, so how about buying them together❓ You can get a ¥700 discount for a combined purchase.
