Maintenance Manual<br />
INTONATION<br />
After you replace the strings or adjust the neck, you must make<br />
fine adjustments to the string length (intonation) to ensure that the<br />
correct pitch is sounded at all frets. Tune the guitar accurately, hold<br />
it in playing position, and compare the pitch <strong>of</strong> the string pressed<br />
down at the 12th fret with the harmonic played at the 12th fret. If<br />
the pitch played at the 12th fret is lower than the harmonic, move<br />
the bridge saddle forward (Fig. 12 A) to shorten the string length.<br />
Conversely, if the pitch played at the 12th fret is higher than the<br />
harmonic, move the bridge saddle backward (Fig. 12 B) to lengthen<br />
the string length. The method <strong>of</strong> adjustment will depend on the<br />
type <strong>of</strong> your bridge, so make adjustments as described in the adjustment<br />
manual.<br />
* Use a tuning meter in order to adjust the intonation accurately.<br />
* The string may break if the saddle is moved a substantial distance,<br />
so be sure to loosen the string before you adjust the saddle.<br />
PICKUPS<br />
By adjusting the pickup height you can make fine adjustments in<br />
the volume and tone. Use a Philips (+) screwdriver to adjust the<br />
adjustment screws (Fig. 13 A) at both sides <strong>of</strong> the pickup, to set<br />
the height <strong>of</strong> the pickup with the string pressed at the last fret. In<br />
general, there should be a space <strong>of</strong> 2~3 mm between the pickup<br />
or pole piece and the string. However, since the optimal pickup<br />
height will depend on the type <strong>of</strong> pickup, your playing style, and on<br />
the character <strong>of</strong> the amp, you should make this adjustment while<br />
listening to the actual sound. The volume will increase as the distance<br />
between the pickup and string decreases, but if the spacing<br />
is too close, the sound may be distorted, or the magnetic field <strong>of</strong><br />
the pickup may cause the string to buzz. Conversely, increasing<br />
the distance between the string and pickup will produce a clearer<br />
sound with less distortion, but the high-frequency range may be<br />
attenuated and there may be less volume.<br />
If your pickup allows the height <strong>of</strong> individual pole pieces to be adjusted,<br />
adjust the pole piece height so that the volume <strong>of</strong> all strings<br />
is well balanced. Depending on the type <strong>of</strong> pole piece, you will use<br />
a minus (-) screwdriver or an Allen wrench to adjust the height<br />
(Fig. 13 B). In particular for the type that uses a (-) screw, please<br />
use caution since there is no limit to the range <strong>of</strong> adjustment.<br />
