Pearl Training Pad This pad has a mesh mute head, and the tension can be adjusted with a tuning key. It can be attached to your knee with a belt. I haven't used it much because I was using it with other training pads and instruments, but it is a used item, so I think there is some wear and tear. Please check the images carefully before considering purchasing. I used it without wearing it on my knee. #pearl #pearl #practicepad #practicepad #percussion #drums
