I recently picked up an ibanez rg7421. The bridge is in fair shape at best, and the saddles absolutely need replacing. Are there any aftermarket bridges that I could install without having to drill new mounting holes for? I would love a hipshot, but I believe the mounting holes don't line up and I would need to drill and fill, which i would prefer to not have to do. Another option would be to just replace the saddles, likely with graph tech string saver. What are your guy's thoughts?
