DOUBLE ACTION TRUSS ROD
THE TRUSS ROD ADJUSTING THE TRUSS ROD
Your instrument is equipped with an adjustable truss rod. It is used to adjust the neck curvature and the distance between the strings and the fingerboard.
Adjusting the neck should be taken when the distance of the strings until the fingerboard is causing playability discomfort, by standing too close or too far from the fingerboard. Depending on the instrument the access to the truss rod can be done in two ways:
By the sound hole
Move away the string to the fingerboard
Approximates the string to the fingerboard
Fig.1
- In the case of the tensor with access from the sound hole of the
instrument, first loosen the 3th and 4th strings and move them
(see Figure 1). In the case of the acess above the instrument nut is
not necessary to loosen the strings.
- Insert the hex key that came with the instrument on the truss rod nut.
(see Fig.1 and Fig.2)
- Turn the key (1/4 turn) in the direction you need to move the neck and
check the result, because this movement usually changes enough the
settings to aproximate or move away the strings from the fingerboard.
If it is necessary, you can make more 1/4 turns until your playability
be ok.
CHECKING THE TRUSS ROD LEVEL
Press the 6th string in the 1st fret and 13th fret and make sure the strings are close to all the frets (fig.4). If not (Fig. 3) tighten the truss rod until eliminate this difference. When the strings get very close to all the frets the neck is aligned

*** IMPORTANT ***
A bad truss rod regulation can seriously damage the neck of the instrument, resulting in the warranty loss. Ideally, this procedure must be done by professionals with experience in this type of setting.
