So I am converting a MIM Fretless Jazz to a fretted Jazz... but I really wanted to use an Aerodyne Jazz neck and a high mass bridge (either the Babicz or Hipshot Type A). The problem is neither of those bridges are high enough. I have never had that problem before. I have had bridges that don't go down low enough so I shimmed the neck, but I have never had to shim a bridge....is it even possible? If so what should I use? Thanks in advance for the help. I am about two seconds away from putting the fretless back together and selling it...and buying a Jazz. But I am looking for something very specific.
