Chapter 1 Play the Sounds!
Turning the Power On
Once the connections have been completed, turn on power to
your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction
and/or damage to speakers and other devices.
1.
If you've connected a device to MIX IN, turn on the
power of that device.
2.
Turn on the power of the GR-20.
After you’ve turned on the power, you’ll be ready to play
when the panel indicators and the display reach the state
shown in the illustration. This state is called “Play mode.”
Before the GR-20 enters Play mode, it will indicate whether it
is currently in guitar mode or bass guitar mode.
• Guitar mode: “
”
• Bass guitar mode: “
”
* For details on how to switch between guitar mode and bass
* This unit is equipped with a protection circuit. A brief interval
(a few seconds) after power up is required before the unit will
operate normally.

3.
Turn on the power of your amp.
Adjusting the Output Level
Use the [OUTPUT LEVEL] knob on the rear panel to adjust
the output level of the GR-20.
Turning the knob toward the right (toward MAX) will
increase the volume. With the knob turned all the way to the
left (toward MIN), the volume will be zero.
* Normally, you should set this near the middle of the range.

Adjusting the Input
Sensitivity (GK SENS)
You’ll need to adjust the input sensitivity of each string
according to your picking strength and how the divided
pickup is installed.
If this adjustment is not made correctly, the system won’t
work properly. You must perform this adjustment to ensure
that you’re taking full advantage of the GR-20’s capabilities.
* Once you make this adjustment, it’s stored within the GR-20;
you won’t need to make it again. However, you should perform
the adjustment again after changing the strings or adjusting
the action of your guitar, or before using a different GK guitar.
* If you’re using a bass guitar, you can use the following table to
convert the string names and indications you see in the display
while performing the procedure below.

Press the [GK SENS] button.
2.
Play only the 6th string.
The left side of the display will show “6,” indicating that
you played the 6th string.
The right digit will show the GK SENS setting. The
BANK indicators will function as a level meter and show
the strength of the guitar signal.
* If the left digit of the display does not show the number of the
string you played, press the HOLD pedal or GLIDE pedal
several times to make the desired string number appear.

3.
Adjust the sensitivity.
Turn the [NUMBER/VALUE] knob to adjust the sensitivity.
The sensitivity will increase as the number in the right of
the display increases. Adjust the sensitivity so that all of
the level meter indicators light briefly when you pick a
note strongly.
