Truss Rod Adjustment - Guild - REV B Owner's Manual

Truss Rod Adjustment

String tension exerts a tremendous bending force
on the guitar neck. Environmental conditions like
temperature and humidity may also cause bowing of
the neck.
Guild guitars have an adjustable truss rod, (or dual
truss rods on all Guild 12-strings), running the length
of the neck that counteracts this force, strengthens the
neck and insures straightness.
A truss rod that is too loose will result in a concave
neck bow, (action too high) and a truss rod that is too
tight will result in a convex neck bow (low action and
fret buzz).
Should the neck of your guitar require adjustment,
first remove the rod cover located on the headstock
above the nut. (The guitar should remain tuned to
pitch during this procedure.) Then insert a Guild truss
rod adjustment wrench p/n 350-9521-000, (or an
equivalent 1/4" nut driver.) See illustration 4.
If the neck has a concave bow, tighten the truss rod
nut by turning it clockwise.
If the neck is humped or has a convex bow, loosen
the truss rod nut by turning it counter clockwise.
Adjust the rod only a partial turn at a time, allow
time for the wood to settle and sight down the neck
after each adjustment. Be careful not to over-tighten
the rod.
If you meet excessive resistance or if you have any
doubts in your ability to make this adjustment
correctly, take your guitar to an Authorized Guild
Service Center. Please note: Truss rod adjustments
are considered to be routine maintenance and will
not be covered under the Guild warranty.
