IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, 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 communi-
•
cations 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.
355
• To avoid possible breakdown, do not use the
unit in a wet area, such as an area exposed to
rain or other moisture.
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, nonabrasive 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.
558b
• To avoid disturbing your neighbors, try to
keep the unit’s volume at reasonable levels
(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.
928
* When turning the bass with GK-2B upside-
down, get a bunch of newspapers or
magazines, and place them under the four
corners or at both ends to prevent damage to
the buttons and controls. Also, you should try
to orient the unit so no buttons or controls get
damaged.
929
* When turning the bass with GK-2B upside-
down, handle with care to avoid dropping it,
or allowing it to fall or tip over.

The GK-2B is a divided pickup designed
especially for bass. You can attach it to a
conventional bass and play the GK-compatible
device for bass from your instrument.
●
Since the divided pickup contains six small
pickups, it can support basses with up to six
strings.
●
The divided pickup allows you to make
adjustments for optimal performance with
basses of the distance between each string of
16 mm–19 mm.
●
Tape and spacers for attaching the controller
are included, making it easy to attach the GK2B securely to your bass.
About the GK-2B’s warranty
Roland guarantees the GK-2B (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 bass or the GK-2B as a result of
your attempt to install or remove the GK-2B.
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.

Names of Things and What They Do
7
Attaching the GK-2B to Your Bass
To use the GK-2B, you need to install it onto a conventional electric bass.
It is not difficult to install the GK-2B, but please read the following items carefully before you begin,
since there are several things that you should be aware of regarding how to attach the divided pickup
and controller.
Cautions for installation
●
Do not use the GK-2B on a bass that has an
unconventional string configuration, a bass
with strings that have no steel core (e.g.,
nylon strings), or on a guitar. It will not
function correctly.
●
Adjustments to the neck of your bass, the
string height, and intonation adjustments
must be completed before attaching the
GK-2B.
●
Before you actually install the divided
pickup and controller, place them against
your bass to verify that there will be no
problems with installation.
We recommend that you use double-sided
●
tape (not screws) to attach the controller first.
Then after you have played your instrument
to verify that there are no problems, use
screws to attach it permanently.
●
If the GK-2B is attached only with doublesided tape or velcro fastener, it may be
dislodged by being jarred while you
perform, or due to the tape loosing its
stickiness over time. Also, depending on the
finish (e.g., lacquer) of your instrument, and
the condition of the finished surface (cracks,
peeling), some of the finish may also peel off
when the tape comes off. Please use the
double-sided tape for temporarily fastening
the GK-2B while deciding on its permanent
location, and use the velcro fastener if you
will be frequently attaching and detaching
the controller.
●
Depending on the type of your bass, it may
be impossible to install the divided pickup
because the space between the bridge and
pickup is too narrow. In this case, it may be
possible to install the GK-2B by modifying
your bass (i.e., moving the pickup). Please
consult your dealer.
■
Installation procedure
1.
Carefully read this manual, and decide the
approximate locations in which you’re
going to place the divided pickup and
controller, and how you’re going to route
the cable.
2.
Adjust the divided pickup as appropriate
for your bass.
3.
Attach the divided pickup to your bass.
4.
Attach the controller to your bass.
5.
Connect the GK-2B to your GK-compatible
device.
6.
On the GK-compatible device, adjust the
sensitivity of the pickup.
* In order to play a GK-compatible device using
the GK-2B, you must adjust the divided pickup
to match the distance between each string, adjust
the height of the divided pickup, and adjust the
sensitivity on the GK-compatible device. These
adjustments are extremely important if you hope
to take full advantage of the performance of the
GK-compatible device. For the adjustment
procedure, refer to the manual of your GKcompatible device after you have finished reading
this manual.
