If you're referring to my version of the Chandler/Parker/Amati/Corky/Muroki bass, then the tailpiece is a plain maple tailpiece I made myself. I am now a little tired of the blond tailpiece look, and will soon replace it with a heavier blackwood model.
I have no idea what tailpiece is used on the chinese version.
I lookes up Chris Threkeld-Wiegend's website

I'm not sure his MOP inlays are to my taste, but there you go. And he uses some
very odd arching styles. I wonder how they sound?
