I've used this bridge on my Music Man S.U.B. bass and the three basic holes barely fit the original holes. Obviously the centre one is fine, but the two on its side are a little bit too large. The screw still fits though. The two other holes on the sides instead are smaller and intended to use withg a screw of course, but the S.U.B. has bigger "screws". I had to adapt it by placing two long screws a bit awry hooking the bottom of the big holes.
Despite all of this it's still stable, solid and works.
