Yamaha out of tune

[Roger Jolly]

Hi Elian,
           It would be well worth while to take a hammer shank and lightly
tap all the strings to the bridges. I have never seen bad coils on Yamaha's
but this is worth a visual check. If you find many of the strings droping
more than 20-25cents this will most lightly be the cause. For best results
quickly pull to pitch before tapping, then retune. I also use the hammer
shank to lightly tap the bridge pins.
Good luck to you. Roger
