NECK ADJUSTMENT
Although the fingerboard is sealed with oils and wax, it is still subject to changes in
temperature and humidity. As humidity increases, the fingerboard absorbs moisture
and expands, forcing the neck to bow away from the pull of the strings. This is most
common going from winter to summer. When humidity decreases, the fingerboard
releases moisture and contracts, forcing the neck towards the pull of the strings.
These changes in moisture content affect only the surface cells of the fingerboard.
They are small and easily adjustable either by you or a qualified repairman.
Your bass is equipped with a special dual action truss rod, which differs from
conventional systems in that it engages in either direction, and will adjust the neck in
both directions, independent of string tension. We have enclosed a special truss
wrench with your instrument. Be sure to keep it with your instrument as you or your
repairman will need it to make adjustments.
