Avoid exposing your instrument to extreme temperatures (such as a car trunk
on a hot day, or when possible, the cargo hold of an airplane). Avoid prolonged
exposure to temperatures below 60º F or above 80º F.
Neck Truss Rod Adjustment
The truss rod in your Breedlove guitar serves to counteract the effect of string
tension on the neck of your instrument. String tension pulls the neck forward
and up, while the truss rod pulls the neck down and backward. A properly
adjusted truss rod equalizes the tension on the neck. Adjustment of truss rod
tension changes the amount of bow in the plane of the fingerboard. Let your
instrument adjust to its new environment before changing truss rod tension.
Truss Rod Adjustments for U.S. Custom Shop Guitars
(except Revival)
To adjust the single-action truss rod on a U.S. Custom Shop Breedlove, remove
the truss rod cover (on the headstock face, just above the nut). Then, using a ¼”
nut driver, turn the brass nut on the end of the truss rod (clockwise to tighten rod
and pull the neck back, counterclockwise to loosen the rod and allow the strings
to pull the neck up. Use a driver extender to ensure that the driver is well clear
of the headstock as the tool is turned.
Make adjustments at full concert pitch.
