This is a Yamaha FP720S. It has been upgraded with Canopus Speed Star bearings, resulting in very smooth action. The beater is a Pearl. It shows signs of use, but I was using it actively until recently. There's no play, and it feels great to play. I definitely prefer the double chain drive of this model over the belt drive of the FP720. It also has an underplate for stability. It's still in great shape and ready to go, so please consider it.
