Regarding GR-20 bass guitar support
The GR-20 you purchased includes system program version 2, which allows the bass guitar range to be supported as well.
By connecting a bass guitar that has a separately sold GK-2B or GK-3B divided pickup (for bass) installed, you can play
the GR-20 from your bass guitar.
When shipped from the factory, the GR-20 is set for use with a guitar. The procedure described below lets you switch the GR-20 between
guitar and bass operation.
* You may repeat this procedure as many times as you like. Furthermore, this procedure will not affect the user patch data.
Switching the GR-20 between bass guitar and guitar operation ..........
1. Switch off the GR-20. Then while holding down the [GK SENS] button, turn on the power.
Shortly afterwards, the display will indicate “ ” or “ .”
2. Use the [NUMBER/VALUE] knob to select bass guitar or guitar operation.
• Bass guitar operation: Turn the [NUMBER/VALUE] knob toward the right (clockwise) to make the display read “ .”
•
Guitar operation: Turn the [NUMBER/VALUE] knob toward the left (counterclockwise) to make the display read “.”
3. Press the [EXIT] button.
The setting will be stored, and you will be in Play mode.
* The decimal point of the display will blink while the setting is being stored. Do not switch off the GR-20’s power while this takes place.
* Please note that the setting will not be stored if you neglect to return to Play mode before you switch off the unit.
* The setting is preserved until you repeat this procedure again.
How the Bass Guitar and Guitar settings differ ...................................
• The range of pitches produced by the GR-20 is switched between guitar and bass guitar ranges.
• In some of the preset patches, this setting causes the actual pitch produced by the synthesizer to be one or more octaves above or
below the pitch that is input. The same applies to user patches that you create based on these preset patches.
(Example) BANK= BASS/GTR No= “Wood Bass”
• When setting the input sensitivity (GK SENS), the numbers shown in the left of the display correspond to strings as shown in the
diagram below.
You must install the GK-2B/3B pickup on your bass guitar as shown below. The system will not operate correctly if you install
the pickup any other way.
Bass Guitar operation The synthesizer will sound at the same pitch as the input.
Guitar operation The synthesizer will sound one octave lower than the input.
