A few years ago I put a Badass bridge on a 51 Reissue Precision. To me it modernised the sound, emphasising the highs and tightening the lows. Not to a point where it would be noticeable in a band mix, just at home volumes. Anyway I swapped it back as it had taken away some of the character of the bass imo. Great piece of engineering, much easier to set up/intonate etc but ultimately not good on that bass.
