Below: New tuners. The deluxe 70.00
set National sells as an upgrade. The big difference I see is an alloy
gear which should be smoother, white buttons, pewter type finish and
some engraving. I can already tell you the holes don't line up for the
mounting screws but otherwise these will work fine. Let me show you
exactly how to do this in a way the tuners will be secure and tune
smoothly.
Tip:
Waverly 3 on a plate tuners will also fit this standard 3 post spacing.
They are more expensive but much better tuners.
