NECK ADJUSTMENT
The neck is constantly bearing the tension of the strings, and its curvature will be subtly affected not
only by the state of tuning and the string gauge, but also by changes in temperature and humidity. If you
experience problems such as string buzz or muted notes even after the action and tuning are adjusted
correctly, you should check and adjust the curvature of the neck.
Check the curvature of the neck
1.
After tuning accurately, hold the guitar in playing
position. Then press the fi rst string at the fi rst
fret and also at the fret that is nearest to the point
where the neck joins the body, and measure the
gap between the string and fret at the eighth fret.
In the same way, measure this gap for the
lowest string, and make adjustments so that the
gaps are in the range of 0.3 mm--0.5 mm.
If the gap is less than 0.3 mm, use the Allen
2.
wrench or socket wrench included with the
guitar to turn the truss rod nut located at the
headstock end of the neck in direction ‘A’,
causing the neck curvature to be more convex.
If the gap is greater than 0.5 mm, turn the
3.
Allen wrench or socket wrench in direction ‘B’,
causing the neck curvature to be more concave.
Adjust the truss rod nut in small increments of a
※
quarter turn, checking the tuning while you do so.
Memo
You must take care when adjusting the neck.
•
Forced adjustments can damage your guitar. If you are unable to adjust the neck correctly, please
contact your dealer or the Ibanez Corporation.
INTONATION
If you’ve changed string gauges or are using
your guitar with an alternative tuning, you’ll need
to adjust the string length (intonation) to ensure
that the correct pitch is sounded at all frets.
After tuning your guitar accurately, hold the
guitar in playing position and compare the pitch
of each string pressed down at the 12th fret with
the pitch of the harmonic played at the 12th fret.
If the pitch of the fretted note at the 12th fret is
lower than the harmonic at that fret, move the saddle of the tremolo/bridge forward to shorten the string.
Conversely, if the pitch of the fretted note is higher than the pitch of the harmonic, move the saddle
backward to lengthen the string.
Use a tuning meter to ensure accurate intonation adjustments.
※
The method of adjusting the saddle position will differ depending on the installed model of tremolo/bridge.
※
For details, refer to the section for the tremolo/bridge that’s installed on your guitar.
