I was in need for a replacement bridge for my Sire V7 bass. I wanted to keep the string-through option, so I decided to try the Gotoh 404BO. I wasn't able to install it without modifications to the body of the bass. The stringoels on the bridge didn't align with the ones on the instrument, but I doubt that this was Gotoh's fault. I was able to fix the issyue by using some epoxy filler and a drill. Now the Sire sounds much more "meatier" and sits much better in the mix when I'm playing with my band. Highly recommended!
