Schaller GrandTune Manual

GrandTune
hypertech tuning
vintage design
Thank you for choosing GrandTune tuners -
the most advanced and musical
machine heads ever built.
Installation:
Please align and drill perpendicularly from the back
of the headstock assuring a perfect 90º angle of the
drill hole.
The peghole should have a diameter of 6 mm.
Do not drill perpendicularly from the top down as
you may be working on a slightly tapered headstock.

On a tapered headstock drilling from the top down
may result in your tuner's backplate to be tilted and
having to be forced into place by the fi xation screws
subsequently bending the tuner's stringpost out of
line. See page 3 vs. page 4
Do not bend the base plate, the worm gear will be
irretrievably destroyed.
