I also have many other brand-name items, eyeglasses, etc. for sale, so please take a look if you'd like. This is Roland's Noise Eater. I used three of them for the hi-hat and double bass pedals. I have three, but I'm also considering selling them individually, one or two at a time. (I personally prefer to sell all three if possible) Also, if I sell them individually, I only have one box for packaging, so I may only be able to use bubble wrap for packing. Please be aware of this before purchasing. Just placing them under the pedals significantly reduces vibrations to the floor during playing, so you can play with peace of mind in apartments or during late-night practice. They provide a significant noise reduction effect. They are in good condition, with some signs of use, but no noticeable scratches or stains. There is some dirt on the back. It's not visible, so I don't think it's a concern, but it is a completely used item. Please check my profile before considering a purchase. Thank you!
