Hello, This is a great forum. Lots of great info.... Thanks. I've dug around and can't find anything regarding the original BadAss bridges. I purchased one and it looks like everything will line up but I've seen some posts that say it's not a direct replacement. If it will bolt up without drilling I will go ahead with it, if it won't I will sell it and get a BadAss II as I know it's a direct replacement. The bass is a 20ish year old MIM Fender Jazz bass and plays nice already but it sounds like the best upgrade you can do is the bridge replacement. Any info on if it will bold on or not would be appreciated.
