Make settings for the divided pickup
3. Press [SELECT/VALUE /] to adjust the sensitivity.
Play the guitar, using what is likely to be the most
forceful playing that you will use in actual performance.
At the same time, adjust the value until the green
indicator in the center is lighted. Then, adjust further
until you get it to the highest value possible without
causing the indicator to the right of that to light.
Higher values will increase the sensitivity.
* The example display shows that the sensitivity for the 6th
string is set at 10.
fig.11-2
* Depending on the guitar that you use, the level may reach the
maximum even if you set sensitivity to the minimum setting.
If this occurs, increase the distance between the divided pickup
and the string so that it is greater than specified.
4. Repeat steps 23 for each of the remaining strings.
5. Play Strings 61 as softly as possible.
If any string produces a particularly loud sound, lower
the sensitivity for that string in order to minimize
volume differences between strings.
Matching the phase of the divided
pickup and the guitar pickup
(6 PHASE)
Unless the phase of the divided pickup and the pickup of the
guitar are matched, they will partially cancel each other out
when they are mixed, adversely affecting the tone or volume.
* With the factory settings, this is set to “1 NORMAL.”
Make sure to set the divided pickup select switch to the
MIX position.
1. Press [PARAMETER /] until 6 is shown (blink) at
the left of the display.
This selects 6 PHASE.
fig.12
2. While playing String 6, press [SELECT/VALUE /]
and select the position that does not cause the volume of
the low-frequency range to diminish significantly.
Get the corresponding number to appear at the right of
the display.
* The example display shows that the 6th string is set to
“1 NORMAL.”
