INTONATION ADJUSTMENT
When the string gauge and/or bridge height is changed, or
the truss rod is adjusted, it is usually necessary
t o
rein-
tonate the bridge saddles. If the guitar plays out of tune in
the higher registers, this adjustment is needed. Check each
string in the following way:
To check intonation, compare the harmonic tone (12th fret)
to the fretted tone (12th fret). Because the 12th fret is the
midway point between the nut and the bridge, a harmonic
tone one octave higher than the fretted tone can be gener-
ated. This is done by barely touching the string directly
above the 12th fret (left hand) and simultaneously plucking
the same string (right hand). If the fretted tone is exactly the
same pitch as the harmonic tone, no adjustments to the
bridge saddles are necessary. However, if the fretted tone is
higher in pitch (sharp) or lower in pitch (flat) than the har-
monic tone, apply the appropriate adjustment as shown
below. Repeat the same procedure for each string.
