Looking to get an authentic Badass II bridge for my P Bass. Surprising there are a number on eBay that are either new in package or OEM. Some of the sellers have been selling them for months looking at their history or they have multiple to sell. I'm hesitant to get one because most have descriptions with little information and with the quanities sold I'm worried if I'm getting an authentic Leo Quan or one someone stamped that says Badass II instead of the Omega Bass. Should I be concerned if I get one from eBay or should I get a used one from a say another TB'er?
