well used Yamaha Double Bass Pedal double-chain-drive double pedal. the left foot isnt quite as responsive as the right, but can be tightened and fixed Still in great shape. I just bought two brand new yamaha beaters for it. double pedals are extremely expensive in beijing, anystore has them pretty pricey, from importing them, and nothin out there for used double pedals..! this is like the only cheap used one available at the moment, in a city of 22 million? strange, anywho. make me an offer, i can get 100 canadian for it back home, so i am asking, 500rmb, but i need to get rid of it fast so make me any offer.. ! i would keep it, i have been using it as a backup, but have to slim down on shipping from gig to gig.
