Chapter 1 Play the Sounds!
Preparing Your Guitar
• In order to use the GR-20 you will need a guitar that has
a divided pickup (GK pickup) such as the Roland GK-3
or GK-2A, or a bass guitar that has a bass guitar divided
pickup such as the Roland GK-3B/GK-2B, which can
independently output a separate signal for each string.
• For details on installing the GK pickup, refer to the
manual that came with your GK pickup.
• Notes may be sounded incorrectly if there are string
buzzes due to improper neck curvature or buzzing frets,
or if the octave adjustment (intonation) is incorrect.
Various guitar manufacturers sell GK-Compatible guitars
that have a pre-installed GK pickup or contain equivalent
functionality. For details, contact your guitar dealer or a
guitar manufacturer.
In order to use the GR-20 with a bass guitar, follow the
procedure described in Chapter 6 Appendices “
Switching
the GR-20 between bass guitar and guitar operation
(p.
32)” to switch the GR-20 to bass guitar operation.
Connections
fig.1-01(Connection)
* To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the power
on all devices before making any connections
* The volume of your amp should be raised only after you have
turned on the power of all your other equipment.
* If you’re outputting in monaural, connect the cable to the R
(MONO) OUTPUT jack.
* To prevent the inadvertent disruption of power to your unit
(should the plug be pulled out accidentally), and to avoid
applying undue stress to the AC adaptor jack, anchor the
power cord using the cord hook, as shown in the illustration.

Also be aware that you
cannot simultaneously
use one jack as a LINE

other as a headphone
jack – that is, you can't
use a monaural plug and
a stereo plug at the same
time.
