Tuning Your Guitar
(Tuner Function)
Since the GR-20 analyzes the pitch of each string in order to
determine the sound it should produce, you must tune your
guitar accurately.
* If your guitar is mistuned, the sound produced will be out of
tune, and the system will not operate correctly.
1. Press the [TUNER] button.
The [TUNER] button will light, and the Tuner function
will be on. The lower two digits of the current reference
pitch will be shown for approximately two seconds in
the display. Then you will be able to tune your guitar.
Example: When the pitch is set to 440Hz
fig.1-05(Reference pitch)
* You can also turn on the Tuner function by pressing the
HOLD pedal and GLIDE pedal simultaneously.
2. Use the [NUMBER/VALUE] knob to adjust the reference
pitch.
If you turn the [NUMBER/VALUE] knob slightly, the
current reference pitch will be displayed for several
seconds. By turning the [NUMBER/VALUE] knob
during this time, you can adjust the reference pitch.
* You can adjust the reference pitch in a range of 427 Hz–452 Hz.
When the GR-20 is shipped from the factory, this is set to
440 Hz.
* The reference pitch you specify will be stored when you exit the
Tuner function. Be aware that the setting will not be stored if
you turn off the power before doing so.
3. Cleanly play an unfretted note on the string that you
want to tune.
The display will indicate the note name.

pitch is being stored. Don't turn off the power during this
time.
