Truss Rod Adjustments for U.S. Custom Shop Revival Series Guitars
To adjust the single-action truss rod on a Revival Series instrument, you will
need a round-tipped 5/32" Allen wrench that is at least 4" long (a special
Revival Truss Rod Wrench is available from Breedlove - please contact us for
details). The adjustment nut is located inside the soundhole, toward the neck.
It is very close to the top of the guitar, and right underneath the fingerboard.
Newer Revival instruments have an access hole through the top soundhole
brace, while older instruments do not. If you do not have an access hole,
note that one of the two neck bolts is also in this general area. The top neck
bolt can be seen through the soundhole, while the truss rod nut is not visible
unless you have the access hole. If you can see your wrench going into a
large bolt, you're in the wrong place! To access the adjustment nut, insert the
wrench into the soundhole between the D and G strings (holding them apart
can be helpful) and point it up toward the area described above to find the nut.
Turn clockwise to tighten the truss rod, or counterclockwise to loosen it.
Generally, a properly adjusted truss rod results in a neck with slight forward
relief. To check for proper neck relief, push down on the low "E" string
at the 1st and 14th frets simultaneously. There should be about 0.010" of
space between the bottom of the string and the top of the 6th fret - about the
thickness of a business card. You may want a larger or smaller amount of
relief depending on your playing style.
Note: The Truss Rod should only be adjusted in order to establish proper
!
neck relief and to counteract/balance the effect of string tension. Do not use
the Truss Rod adjustment feature to try to correct larger set-up issues or other
problems that are not related to neck relief.
