About the Workshop Booklets
Roland’s GR-20 Guitar Synthesizer opens up spectacular new sonic
possibilities for the electric guitarist. With the included GK-3 Divided
Pickup installed, any six-string electric guitar can play the GR-20’s amazing
collection of synthesizer sounds and sampled real-world instruments. You
can also mix your guitar’s own sound with those in the GR-20 to create new
timbres that are all your own.
Each GR-20 Workshop Series booklet focuses on one GR-20 topic, and is
intended as a companion to the GR-20 Owner’s Manual.
This booklet requires GR-20 O.S. Version 2.00 or higher. You can download
the latest GR-20 O.S. for free from www.RolandUS.com.
About This Booklet
This booklet shows you how to set up the GR-20 for your playing style, tune
your guitar with the GR-20, and how to select and play GR-20 patches.
We’ll assume that a GK-3 has been properly installed on your guitar by you
or a guitar technician, or that you’ve purchased a GR-compatible guitar from
Godin, Brian Moore, Ibanez, Fender, or another guitar-maker. (To learn how
to install a GK-3, see its Owner’s Manual.)

Connecting the GR-0’s Outputs
When you’re using:
a mono guitar amp—connect the GR-20’s rear-panel OUTPUT R (MONO)
jack to the amp’s input using a standard 1/4” instrument cable.
a stereo guitar amp, two mono amps, or a stereo mixer or recorder—
connect the GR-20’s rear-panel OUTPUT L (PHONES) and R (MONO)
jacks to the other device’s left and right inputs, respectively.
headphones—connect a standard 1/4” stereo headphone plug to the
GR-20’s rear-panel OUTPUT L (PHONES) jack.
About the GR-20’s Smart Jacks
When you’ve connected cables to both the OUTPUT L (PHONES) and R
(MONO) jacks, the GR-20 sends one side of its stereo mix to each jack, since
it assumes you’re connected to a stereo receiving device. Therefore:
to listen to the GR-20 through headphones—make sure you haven’t
plugged anything into the OUTPUT R (MONO) jack.
to send the GR-20’s entire mix to a mono amp—make sure nothing’s
plugged into the OUTPUT L (PHONES) jack.
