Thank you for viewing. This is a cup mute for a Denis Wick bass trombone. I purchased it about 10 years ago, but I didn't use it much and it has been stored in its box. Although it has been some time, there are a few spots that show some dirt, but there are no major scratches or dents. The outer box is a little damaged, and there is a place that has been repaired in the past. The cork has not been adjusted and is in the same condition as when it was purchased. The cup part is removable, and it can be removed and used as a straight mute. Please consider using it. Please understand that this is a used item before considering a purchase.
