HOW TO ADJUST THE NECK WITH ADJUSTABLE TRUSS ROD
The neck of your guitar is adjustable. It has been made of selected hardwood, properly cured.
It is kiln dried to insure proper curing. The adjustable rod both strengthens the neck and facilitates
adjustment of bowed neck. Because all guitar necks are subject to great stress as a result of string
tension and climatical change, there are times when a neck will take on a slight bow (or warp)
or neck hump. This will rarely occur. However, if it does, there is no cause for alarm if you
follow the procedure below for proper correction. .
A HEADPIECE TYPE OF ADJUSTABLE TRUSS ROD
1. Loosen 3rd and 4th strings( do not remove strings from guitar).
Pull loose strings to one side so free access to nut cover can be obtained.
2. Remove cover so neck adjustment nut is exposed.
3. Sight down the neck from the top in order to see just how much of a bow
or hump the neck has taken.
Note:Hold the neck up at eye level and sight along the edge of the fingerboard on both the
treble and bass sides.
4. If neck is bowed, tighten adjustable nut!
6. Place guitar wrench on adjustment nut and turn very gently (small fraction of a turn at a time).
Keep checking the neck as you proceed with each nut turn.
Once the neck is straight give the adjustment nut a very slight added turn to compensate
for the tension the 3rd and 4th stings will add once they are replaced and tuned.
Special Note: When making this adjustment, it is best to place a straight-edge on the frets
to assure a perfect adjustment.
Be careful not to tighten the nut too much (i. e. when' it becomes hard to turn), because it could
result in stripping the threads or perhaps even breaking the truss rod.
On certain models of solid body electric guitars adjustment of the truss rod is made at the
lower end of the fingerboard. However, the procedure of adjustment is the same as above;
Follow the same pattern of correction as outlined in article A HEADPIECE "TYPE" OF ADJUSTABLE TRUSS ROD.
If there is string buzzing after you are certain the neck has been straightened,
locate the fret at the playing position that causes the buzz.
Lower the fret by gently tapping with hammer.
If necessary, file fret down.
