Connections
MIX/GUITAR INPUT jacks
The sound of other devices can be input here. This
input sound will be mixed with the sound of the
GR-D and output via the OUTPUT jacks.
* If nothing is connected to the GK IN connector, the L/
MONO jack will function as the GUITAR INPUT jack. You
can connect a non-GK-compatible guitar using a 1/4"
phone plug. *1
GUITAR OUTPUT jack
Normal pickup signals of the
GK-compatible guitar are output.
By connecting another effects unit
and returning its signal to the MIX
INPUT jacks, you can use the unit for
send/return applications.

If you've connected your guitar to the GUITAR INPUT jack using a 1/4" phone plug, the signal from each string cannot be processed
individually, so you won't be able to enjoy the full potential of the GR-D.
Basic Connection
Connect the GR-D to the GK-compatible guitar using dedicated GK cable.
GK-compatible
guitar
Connect the GK-compatible
guitar only with dedicated GK
cable (supplied with Roland
GK-compatible devices and
optional GK cables sold by
Roland). Use of any other
cable may result in damage
or malfunction.
* To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
GK IN
connector
Connect the
GK-compatible
guitar using
dedicated GK
cable (sold
separately).
OUTPUT jacks
Connect these jacks to your guitar amp or to another effects unit.
* Use the [SELECT] switch to specify whether these jacks are connected to a guitar
amp (G. AMP) or to a line-level device (LINE).
* The OUTPUT L jack also operates as a power switch. The power will be on if a
plug is inserted in the OUTPUT L jack. Remove the plug when you're not using the
GR-D.
When connecting the GK cable,
insert the connector completely,
until it is locked.
You can disconnect the cable
simply and easily by holding
down the locking portion with
your thumb and gently pulling on
the plug.
DC IN jack
This jack is for connecting an AC adaptor
(BOSS PSA series; sold separately).
* Use only the specified AC adaptor
(PSA series), and connect it to an AC
outlet of the correct voltage. Do not
use any other AC adaptor, since this
may cause malfunction.
When connecting to
the guitar amp, set
the [SELECT] switch to
"G. AMP. "
To get the best performance from the GR-D, we
recommend that you set your amp to "Clean" (no
distortion).
Always turn the amp volume down completely
before connecting and disconnecting cords.
