Double chain drive 9000 model twin pedal, with carrying case. Selling to organize my equipment. I used this as my main pedal for a while, so it shows signs of use, but it functions perfectly well. The accessories are still in the case, so I believe they are all there and usable. One of the height adjustment parts for the beater is missing, so I'm selling it as is. Also, both beaters likely have weights purchased from Canopus attached. No claims and no returns. Model: 9000 Accessories: Carrying case Mechanism: True-circle cam type - Brand: dw Thank you for looking.
