The neck is equipped with a steel truss rod that can be used to adjust the relief to
your preferences.
After tuning the strings, check the relief by pressing on the low E string at the first
and twelfth fret. The closer the string is to the fingerboard at the sixth fret, the more
noise (buzz) will be audible when the guitar is played.
Adjust the neck relief using an appropriate Allen key as follows:
n
Turn the truss bar clockwise to increase tension. The neck will become straighter,
even convex in extreme cases. The string will be closer to the fingerboard, is
easier to fret, but will buzz more during playing.
n
Turn the truss bar counterclockwise to decrease tension. The neck will respond
more to the string tension and become correspondingly more concave. The
string will be farther from the fingerboard, be somewhat harder to fret, but will
cause less or no noise during playing.
Adjust the truss bar only by about a quarter turn per setting, then retune all the
strings to the correct pitch and check the neck relief again after a short time. Repeat
this process until the desired neck relief is reached.
Once the neck has the desired relief, you can use the screws for each saddle to adjust
the string position to suit your taste. Here, too, the lower the strings, the easier they
are to fret, but they will buzz more easily when the guitar is played.
