VRUK Drum Master Brook Drum Master This is a drum accessory that attaches to the bass drum pedal to support your playing. It has been used very little, so there are no noticeable stains or scratches, but the rubber parts show signs of deterioration due to the time elapsed since purchase. The screws used for fixing have manufacturing imperfections, and it may be difficult to tighten them properly with some tuning keys. This was the case from the time of purchase, so if you are concerned, we recommend replacing them.
