    I have a 1981 greco supersound precision bass and it is quite neck heavy. I would like to install gotoh resolite gb528 tuner on this bass but I`m not sure...

    My bass headstock has holes about 17..18 mm, but gb528 bushings are 16 mm. Can I still use this tuners? Maybe I could put some tape around bushings, if it does not affect the sound in bad way?

    Or would you suggest gotoh resolite gb640 over gb528? gb640 bushing should be perfect match to my headstock holes, but I still think that I would prefere gb528 because they are ligther. The screw holes don't match anyway. If I choose gb640, then I should drill new screw holes very near to old ones and I am afraid that will be a mess. And I want keep possibility to reinstall the old ones if needed.

    Has anyone experience on this topic?

    The Schaller M4S light has a 16.8 mm bushing. They are heavier at 71 grams. Instead of screws on the rear there are alignment pins just about where you screws would go. That 12 gram difference could be the size of the bushing and the alignment pins.
