Hi guys! I'm new to this forum since I've only recently picked up playing bass. I have a MIM Jazz Bass and I am not satisfied with behavior of stock bridge (screws loosen up and strings go too high or too low). I have noticed that a popular upgrade for a JB is BadAss II bass bridge. My question is - is it a direct replacement requiring no drilling in body? It looks like it is but I'm not sure if there is only one type of stock MIM JB bridge.
