Action Adjustment:
� Feeler gauge
� Allen wrench to adjust truss rod
� Radius gauge
The action is the height of the strings from the fret board and
is usually measured at the 1
st
or 12
th
fret. Strings that are set high
above the fret board are known as
“High-action” the opposite goes for
strings that are set low. The Action of a
guitar is important when determining
its playability. If the action is too low,
then it can cause string buzzing. If the
action is too high then it will start to
become uncomfortable and difficult to
play. So it’s good to find a median
where it is high enough to not cause
string buzzing but also low enough to be comfortable. Picking an
action adjustment will also depend on the preference of the player
Drastic changes in the temperature will
either cause the wood in your guitar to shrink or expand. As a result
the neck will start to slightly bow which caused the action of the
strings to change.
If you change the tension of your strings from high to
low and vice-versa then it could result in neck bowing and have a
similar effect as temperature changes.
Extended use can cause the nut of your guitar to
wear down. When this happens, it could affect the action of your
guitar.
