Roland V-Drums Dedicated Setting Mat TDM-20 Used item. Selling because I no longer use it. * This is a used item, so no claims or returns are accepted. * Please refrain from purchasing if you are sensitive to used items. Thank you for your understanding of used items. This is a setting mat specifically designed for V-Drums, which can reduce vibrations to the floor during performance. The three-layer construction with thick material absorbs vibrations. It also prevents scratches on the floor from the spikes of the kick pad and hi-hat pedal, even in rooms with flooring.
