Hi, folks... I have a 75 Jazz Reissue (American) I picked up some years back off of eBay. The original owner had swapped the bridge with a Hipshot A style bridge. The problem is that I can't intonate the bass. No matter how close to the neck I get the saddles (the entire length of the screw), the fretted notes are running flat. The neck is set up nicely, but it's at least 15 cents flat on each string. Is this common? I'm considering finding an original bridge, but let me know your thoughts on if that will solve the problem. It is definitely a hearable difference.
