2) Truss rod cover / Truss rod adjustment
Truss rod cover:
The truss rod cover of a RockBass
®
gives you - when needed - quick access to the truss rod. You’ll need a flat
screwdriver to unlock the integrated latch mechanism.
Truss rod adjustment:
A neck is set up correctly if it has a slight forward bow. You can easily verify this by pressing the lowest string at the
1st and last fret and measuring the distance between the fret and the string at the 7th fret: it should read between
0.6 and 1 mm (0.02” and 0.04”). This value is independent from the action (height) setup of each individual string.
Turning the truss rod key clockwise (direction A) will tighten the truss rod and give the neck a back bow. Turning the
truss rod key counterclockwise (direction B) will loosen the truss rod and give the neck a forward bow. These adjust-
ments should be done in small steps because the neck’s reaction is not instantaneous. You should check the results
after approximately one hour and probably check again the following day. Readjust the truss rod if needed.
A change in humidity, particularly during the changing of seasons or during strong weather fluctuations, is when one
should pay attention to the neck’s setup and the corresponding truss rod adjustment.
Direction A = back bow
Direction B = forward bow
