I am selling my drum hardware as I am moving. It functions without any issues. Regarding the difference from the DFP8500, this 9500 model allows for independent adjustment of the pedal board angle and beater angle. Also, the original beaters are prone to breaking, so I have replaced them with Pearl 2-way beaters. One of the beater mounting screws is new. I used it for about six months in a studio with a mat, and then stored it in a cardboard box for about three years. No pets, no smoking. This is the final price.
