The Truss Rod - What It
Is What It Does
How to Adjust It
If thinking about removing that little plate and
taking out an Allen wrench makes you feel a bit
faint, please see your local guitar shop (where you
bought your Spector) and have them help you
out. All Spector Basses have an adjustable rod
located in the neck which runs the length of the
neck. The truss rod opposes the force exerted by
the tuning of the strings and keeps the neck from
warping under that pressure.
Many of our basses also have graphite rods that
run parallel to the truss rod and act to evenly
distribute the forces of the truss rod. If “sighting
down” the neck indicates that there is a warp or
“dip” in the neck, the adjusting nut should be
tightened. If there is a reverse warp or “hump” in
the neck, the nut needs to be loosened.
When in doubt, please consult with your local
Spector dealer or qualified guitar repair shop!
CAUTION: There are very extreme forces involved in
basses and bass
strings. BE SURE TO LOOSEN STRINGS
before attempting to tighten the truss rod!
IMPORTANT: If you have ANY question
about your comfort level in doing neck
adjustments on any instruments, we
highly recommend that you return to
your Spector Dealer and ask them for
assistance.
VERY IMPORTANT: Truss rods can be
tightened. They can also be can be
tightened too far! When in doubt, seek
professional advice.
