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

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.

Attaching the GK-2B to Your Bass
1. Adjusting the divided pickup
In the case of basses, the distance between each string differs between instruments, so you will need to
adjust the divided pickup according to the distance between each string of your bass. Unless this
adjustment is made accurately, the GK-compatible device will not function at its full potential, or may
not operate correctly. Please make this adjustment with care.
1.
Measure the distance between strings on
your bass.
To determine the distance between each string,
you can measure the distance between string 1
and string 4 (or depending on the number of
strings, 5 or 6) at the location in which to install
the pickup (p.13–14), and divide by one less
than the number of strings (i.e., in the case of a
four-string bass, divide by three).
fig.03_e

Measure the distance
between these two strings.
Example: a distance of 57 mm
57 divided by (4-1) = 19 mm
2.
Use the included screwdriver to loosen the
screws, move the markers to the position of
the appropriate the distance between each
string, and tighten the screws.
* Be careful not to tighten the screws excessively.

Attaching the GK-2B to Your Bass
2. Attaching the divided pickup
The divided pickup can be attached in one of two ways:
●
Using double-sided tape
●
Using screws
Using double-sided tape is the easier method, and is generally recommended.
Using screws has the advantage that you will be able to adjust the distance between the strings and
pickup when necessary, but the procedure is somewhat more difficult than when using double-sided
tape.
* Do not apply excessive force to the cable that connects the pickup to the controller. Doing so may sever the
conductors inside.
* Do not bend, twist, or otherwise apply force to the pickup. Be particularly careful when attaching or
removing it. Do not intentionally apply force to the pickup cover.
fig.06
■
Attaching the pickup with double-sided tape
Double-sided tape of a type that can be easily
peeled off is also provided (p. 10).
Use this tape if you will want to adjust the
position of the pickup, or if you may want to
remove it.
The installation method is the same as when
using the regular double-sided tape, but you
should peel off the regular double-sided tape
from the side of the spacer or divided pickup
that contacts the body of the bass, and replace it
with the easily peeled double-sided tape.
* Please observe the following points when using
the reusable double-sided tape.
• If you use this tape to attach the divided
pickup, the divided pickup may fall off at a
later time due to physical shock during
playing, or due to ageing of the tape.
• This tape will not stick to the pickup cushion.
• This tape is 0.1 mm thick. Take this into
account when you adjust the height of the
divided pickup.

1.
You decide on the location in which to
install the pickup.
For a four-string bass:
Attach the divided pickup so that the center
marker is between strings 2 and 3, the 2nd
string marker is directly below string 1, and the
5th string marker is directly below string 4.

* Depending on the GK-compatible device, it is
possible to install the pickup so that the center
marker is between strings 1 and 2, or between
strings 3 and 4. Refer to the manual for your
GK-compatible device.
For a five-string bass:
Attach the divided pickup so that the center
marker is between strings 2 and 3, the 2nd
string marker is directly below string 1, and the
5th string marker is directly below string 4.
fig.08_e
String

* Depending on the GK-compatible device, it is
possible to install the pickup so that the center
marker is between strings 3 and 4. Refer to the
manual for your GK-compatible device.
Bridge
* Route the pickup cable so that it can be smoothly
connected to the controller, and will not get in
the way of operating the controls of your bass.
fig.11
13
Attaching the GK-2B to Your Bass
* Install the divided pickup as close to the bridge as
possible. Regardless of the type of bass, do not
install the pickup more than 50 mm away from
the bridge.
fig.12_e
maximum 50 mm
When you have decided on the location in
which to install the pickup, use pencil or
tape to mark that location.
2.
Make sure that the neck tension and string
height are optimally adjusted, and then
tune each string.
If your bass is not set up optimally, be sure
to adjust it to the optimal state before you
tune.
3.
Adjust the height of the pickup.
Insert pickup spacers below the divided
pickup until you reach the necessary height.
(Do not yet peel off the protective backing.)
There are two types of pickup spacer, A
(thick) and B (thin), and these can be
combined as necessary.
Adjust the pickup height so that there is
approximately 1.5 mm of space between the
string and pickup when you press the
highest fret of each string.
fig.14
1.5 mm
Using the clearance gauge
The included clearance gauge is
approximately 1.5 mm thick. Insert it
between the strings and the divided pickup
as shown below to check and adjust the
spacing.
fig.41
* If you are attaching the pickup to a bass with a
curved surface (arched top), place a pickup
cushion beneath the pickup spacer.
fig.13_e
Pickup Spacer
Pickup Cushion
* The pickup spacers and pickup cushions are
attached with double-sided tape. Peeling off the
backing sheet will reduce the thickness by
approximately 0.1 mm. If you are using
numerous spacers or cushions, you will need to
increase the height to compensate for this
reduction in thickness.
* If the distance between the string and pickup
when the highest fret is pressed differs
significantly between string 1 and the lowest
string, cut a spacer in half or a third, and add it
underneath the lower end of the pickup so that
the gap is approximately the same for both sides.
14
Attaching the GK-2B to Your Bass
4.
Loosen and remove the strings.
5.
Remove the protective backing from the
double-sided tape of the pickup cushions,
pickup spacers, and divided pickup, and
affix them to your bass.
6.
Reinstall the strings, tune your bass, and
then check the height of the divided pickup
once again. Then attach the cable hook near
the bridge, and fasten the pickup cable in
the hook so that it does not lift up or touch
the strings.
fig.15_e
Cable Fook
* At this point, we recommend that you
temporarily connect your GK-compatible device,
and check the level of each string. If there are
significant differences between the levels of the
strings, make fine adjustments to the position
and height of the pickup so that the levels are as
consistent as possible.
7.
If the pickup height was not appropriate,
use the following procedure to correct it.
(1) Carefully examine the current state. If
the pickup is too low, decide how many
spacers you need to add. If it is too
high, decide how many spacers you
need to remove.
(2) Loosen and remove the strings.
(3) Pry off only the divided pickup from
the bass.
* If you bend or twist the divided pickup, the
internal circuitry could get damaged. Please use
care in removing it.
Insert a thin object such as a table knife below the
pickup, starting at the lowest string, and gently,
little by little, pry it off.
fig.16
(4) After you have taken off the pickup,
completely remove the double-sided
tape from the bottom of the pickup. It
can be removed cleanly by rolling it
with your finger as shown below.
fig.17
(5) Adjust the height. When adding a
spacer, remove the double-sided tape
that remains on the upper surface of the
spacer already affixed to your bass, and
attach the additional spacer on top of it.
When removing a spacer, you should
also remove any double-sided tape that
remains on the top surface after peeling
off the unneeded spacer.
(6) On the bottom surface of the pickup,
attach two new strips of the included
double-sided tape B.
(7) Attach the pickup on top of the
spacer(s) you affixed to your bass.
(8) Reinstall the strings, tune your bass,
and check the pickup height.
* After this procedure, the next step is to adjust the
pickup sensitivity on your GK-compatible device.
However, in some cases, you may find that the
level meter of the GK-compatible device is
already stuck at its maximum level. Should this
be the case, you may be able to solve the problem
by increasing the space between the strings and
pickup. Perform steps (1) through (8) to slightly
lower the height of the pickup.
15
Attaching the GK-2B to Your Bass
■
Attaching the pickup with screws
The procedure for determining the location and
height of the divided pickup is exactly the same
as when using double-sided tape to fasten the
GK-2B. Please carefully read “Attaching the
pickup with double-sided tape” before you
continue.
* In order to install the pickup with screws, there
must at least 15.5 mm between the body and the
strings. If you are attaching the pickup to a bass
on which there is less than 15.5 mm of clearance
between the body and the strings, cut the springs
to an appropriate length.
1.
Decide where you’re going to install the
pickup. When you have decided on the
location, mark the body of your bass to
indicate the locations of the holes at each
end of the pickup.
2.
Loosen and remove the strings.
3.
Drill pilot holes at the marked locations.
* If the pilot holes are not located accurately, the
pickup will not be positioned correctly. Be very
careful when drilling the pilot holes.
* A diameter of approximately 2 mm is appropriate
for the pilot holes.
* If the body of your bass is made of a hard
material, make the pilot holes slightly larger than
2 mm.
4.
As shown below, insert the springs
between the pilot holes and pickup, and
fasten the screws.
fig.18
5.
Reinstall the strings, and tune your bass.
6.
Adjust the height of the pickup.
* Tighten or loosen the screws so that there is
approximately 1.5 mm of clearance between the
string and pickup when the highest fret is
pressed. Use the included clearance gauge (1.5
mm thick) to adjust or check the height.
* After this procedure, the next step is to adjust the
pickup sensitivity on your GK-compatible device.
However, in some cases, you may find that the
level meter of the GK-compatible device is
already stuck at its maximum level. Should this
be the case, you may be able to solve the problem
by increasing the space between the strings and
pickup. Perform step (6) to slightly lower the
height of the pickup.
16
Attaching the GK-2B to Your Bass
3. Attaching the controller
There are two ways to install the controller:
●
Using double-sided tape or velcro
●
Using screws
Using double-sided tape or velcro to install the controller is the easier method, but the controller may
come off if your bass is jarred during performance or as the tape ages. We recommend that you
consider these methods as temporary, and in general use screws to attach the controller.
2.
■
Attaching the controller with double-sided tape or velcro
If you do not want to make holes in the body of
your bass, use double-sided tape or velcro to
attach the controller.
However, with this method, the controller may
come off if your bass is jarred during
performance or as the tape ages.
Also, depending on how decals are affixed, the
condition of the finished surface (cracks,
peeling), or how your bass is finished, decals or
finish may also come off of your instrument
when the tape comes off.
Use the included velcro fastener if you will be
frequently removing and re-attaching the
controller.
When you have decided where to install
the controller, wipe off any moisture, oil, or
dust from that location.
3.
Affix double-sided tape or velcro to the
bottom of the controller.
fig.42
MADE IN JAPAN
GK-2B
1.
Place the controller on the surface of your
bass, and decide where you’re going to
install it. At this time, keep in mind the
following points.
* Is the controller where it will not interfere with
your playing?
* Is the controller in a position where it can be
operated easily?
* Will the controller interfere with the divided
pickup?
* Is strain being placed on the normal pickup input
jack, the divided pickup, or the GK connector
cable?
* Do the plugs inserted in the GK connector or
normal pickup input jack protrude beyond the
bass? If they protrude, strain may be placed on
the GK connector or normal pickup input jack
when the bass is set down, damaging them.
4.
Attach the controller to your bass.
* If you are attaching the controller to a bass with a
rounded body (e.g., an arched top), there may be
gaps between the controller and the bass, making
it difficult to attach the controller. In this case,
affix the included controller spacers to places on
the body where such gaps appear.
Use a knife or scissors to cut the body spacer to
an appropriate shape.

Attaching the GK-2B to Your Bass
fig.43_e
Controller Spacer
■ Attaching the controller
with screws
1. Place the controller on the surface of your
bass, and decide where you’re going to
attach it.
At this time, keep in mind the following points.
* Is the controller where it will not interfere with
your playing?
* Is the controller in a position where it can be
operated easily?
* Will the controller interfere with the divided
pickup?
* Is strain being placed on the normal pickup input
jack, the divided pickup, or the GK connector
cable?
* Do the plugs inserted in the GK connector or
normal pickup input jack protrude beyond the
bass? If they protrude, strain may be placed on
the GK connector or normal pickup input jack
when the bass is set down, damaging them.
2. When you have decided where to attach the
controller, place the controller on that
location, and from above, drill pilot holes
into the body of your bass through the
holes in the controller.
* Before you drill pilot holes, check once again to
make sure that there are no problems with how
the divided pickup is installed.
* A diameter of approximately 2 mm is appropriate
for the pilot holes.
Affix double-sided tape to the bottom of the
3.
controller, and fasten it using the included
screws (flat headed tapping screws).

Put the screw (flat-head) through this hole.
* If you are attaching the controller to a bass with a
rounded body (e.g., an arched top), there may be
gaps between the controller and the bass, making
it difficult to attach the controller. In this case,
affix the included controller spacers to places on
the body where such gaps appear.
Use a knife or scissors to cut the body spacer to
an appropriate shape.

Operation
Getting connected
* To prevent malfunction, and/or damage to
speakers and other gear, make sure to turn down
the volume on all your devices, then turn off their
power before you hook anything up.
* Once you’re hooked up correctly, follow the
procedure below to turn on the power. If you fail
to follow this procedure, the system may
malfunction, or your speakers may be damaged.
1. Make sure that your GK-compatible device
is turned off, and then use a GK cable to
connect the GK-2B to your GK-compatible
device.
* Connect the GK connector of the GK-2B to your
GK-compatible device.
fig.32_e
GK Cable
* The GK cable includes a locking mechanism, so
do not pull it with excessive force. Release the
lock and disconnect the cable. Press the lock with
your thumb and slide the plug out to disconnect
it easily.
fig.33
GK IN
GK-compatible Device
* To make connections to a GK-compatible device,
use a GK cable (GKC-3/5/10) or the special cable
included with the GK-compatible device. Never
use any other cable, since doing so may cause
malfunction.
19
Operation
* When performing, be sure to pass the GK cable
through your strap near the end pin of your bass.
If you fail to do this, excessive force applied to the
cable may damage your bass.
fig.34
2. Connect the large plug of the normal bass
cable (included with the GK-2B) to the
output jack of your bass, and connect the
small plug to the normal pickup input jack
of the GK-2B.
fig.35_e
* This connection is used when playing the normal
sound of your bass alone, or mixed with the
sound of the GK-compatible device, and also in
order to create a common electrical ground
(earth) for the bass and the GK-compatible
device. For this reason, you must make this
connection even if you are not using the normal
sound of your bass at all. If this connection is not
made, noise may occur.
3. Turn on the power of the GK-compatible
device.
The power indicator of the GK-2B will light.
Now you can play your bass to play the
connected GK-compatible device.
* The power indicator will not light unless the
following two conditions are met. Nor will the
power indicator light if you have connected a
GK-compatible device that is not self-powered,
such as the GKP-4 or US-20.
(1) The GK-compatible device and the GK-
2B must be correctly connected using a
GK cable.
(2) The power of the GK-compatible device
must be on.
