Intonation
 |
Intonation adjustment is the operation
of adjusting the location of the string
at the saddle to compensate for different
string gauges or different tunings.
Follow the instructions of the particular
bridge intonation below. Intonation is
properly set when the 12th fret note
and the 12th fret harmonic are exactly the
same note. This is the center point
of the scale and the most accurate way of
setting a standard scale length. With
the harmonic note as the standard, if the
fretted note is flat, move the bridge
saddle forwards toward the headstock (a)
to decrease the string length. If the
fretted note is sharp, move it back away
from the headstock (b) to increase
the string length intonation adjustments.
* Please note that strings can be broken when the saddle is moved, so always loosen the strings before making adjustments
