IMPORTANT NOTES
291a
In addition to the items listed under “USING
THE UNIT SAFELY,” please read and
observe the following:
Power Supply
307
• Before connecting this unit to other devices, turn off
the power to all units. This will help prevent malfunctions and/or damage to speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or other
equipment containing large power transformers)
may induce hum. To alleviate the problem, change
the orientation of this unit; or move it farther away
from the source of interference.
352b
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the
vicinity of this unit. Such noise could occur when
receiving or initiating a call, or while conversing.
Should you experience such problems, you should
relocate such wireless devices so they are at a
greater distance from this unit, or switch them off.
354a
• Do not expose the unit to direct sunlight, place it
near devices that radiate heat, leave it inside an
enclosed vehicle, or otherwise subject it to temperature extremes. Excessive heat can deform or
discolor the unit.
355b
• When moved from one location to another where
the temperature and/or humidity is very different,
water droplets (condensation) may form inside the
unit. Damage or malfunction may result if you
attempt to use the unit in this condition. Therefore,
before using the unit, you must allow it to stand for
several hours, until the condensation has
completely evaporated.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry
cloth or one that has been slightly dampened with
water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a
soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
553
• Use a reasonable amount of care when using the
unit’s buttons, sliders, or other controls; and when
using its jacks and connectors. Rough handling can
lead to malfunctions.
556
• When connecting / disconnecting all cables, grasp
the connector itself—never pull on the cable. This
way you will avoid causing shorts, or damage to
the cable’s internal elements.
558a
• To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels. You may prefer
to use headphones, so you do not need to be
concerned about those around you (especially
when it is late at night).
559a
• When you need to transport the unit, package it in
the box (including padding) that it came in, if
possible. Otherwise, you will need to use equivalent packaging materials.
562
• Use a cable from Roland to make the connection. If
using some other make of connection cable, please
note the following precautions.
• Some connection cables contain resistors. Do not
use cables that incorporate resistors for connecting
to this unit. The use of such cables can cause the
sound level to be extremely low, or impossible to
hear. For information on cable specifications,
contact the manufacturer of the cable.

How to
Connect the GK-3 .......... 18
The GK-3 is a special divided pickup, which,
when installed on an ordinary guitar, allows
you to use the guitar to play the sounds of
GK-compatible guitar devices (Roland GR20 or VG-88 etc.).
• The pickup’s adjustable curve mechanism
makes the GK-3 compatible with guitars
with different fingerboard (string) curves.
• Included with the GK-3 are special
holders, spacers, and other accessories,
which allow you to easily attach the unit
to any of a wide variety of guitar models.
• You can use the controller switches to
control the various functions of
connected GK devices.
About the GK-3 Warranty
Roland guarantees the GK-3 (and all
included parts) to be free of defects in
materials and workmanship. Contact your
retailer or nearest Roland Service Center if
repairs become necessary.
Roland cannot be responsible for any
damage caused to your guitar or the GK-3 as
a result of your attempt to install or remove
the GK-3. If you are not confident with your
ability to properly install the Pickup or
Controller unit (especially where drilling is
involved), please contact your Roland
retailer or nearest Roland Service Center.

Attaching the GK-3 to the Guitar
The GK-3 can be attached to and used with conventional electric and acoustic guitars.
Please read the following precautions before installing the GK-3.
Precautions Before Installing
• Do not use the GK-3 with 12-string
guitars or guitars with other unusual or
customized string setups, guitars strung
with non-metal core nylon strings. The
unit will not function properly with these
instruments.
• Make any adjustments to the guitar neck,
string height, and other such
modifications before installing the GK-3.
• Try placing the divided pickup and the
controller unit on the guitar before
actually attaching them to confirm that
there will be no problem with the
installation.
• When using the screw to attach the
controller, we recommend that you first
attach the GK-3 temporarily using the
holder, then after confirming that there
are no problems when actually
performing with the unit, secure it with
the screw.
• If only the double-sided tape is used to
attach the controller, shocks from rough
handling during performances and from
extended use will cause the tape to
deteriorate, with the controller shifting
out of position as a result. Also, if the
finish on your guitar is less than perfect,
you may discover that the finish is also
removed when you later remove the tape.
The supplied tape is intended to be used
only very temporarily, to help you
determine the optimum position for the
controller.
• With certain guitars, the space between
the pickup at the bridge position and the
bridge itself is too narrow to allow
installation of the divided pickup. In such
instances, it may be possible to attach the
pickup by modifying the guitar (for
example, by moving the bridge pickup
more towards the neck to make room for
the divided pickup); consult your guitar
dealer.
