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.

Page 6
Attaching the GK-3B to the Bass
The GK-3B can be attached to and used with conventional electric basses. Please read the
following precautions before installing the GK-3B.
Precautions Before Installing
• Do not use the GK-3B on basses with
doubled strings or other highly
customized basses, piccolo basses and
other basses with unusual tunings, or
basses with other non-metallic core
strings. The pickup may not function
properly in such cases.
• Make any adjustments to the bass neck,
string height, and other such
modifications before installing the GK-3B.
• Try placing the divided pickup and the
controller unit on the bass 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-3B temporarily using the
special 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 bass 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 basses, 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 bass (for
example, by moving the bridge pickup
more towards the neck to make room for
the divided pickup); consult your bass
dealer.
• When attaching the GK-3B to the bass,
you should try to orient the unit so no
buttons or controls get damaged, and
handle with care to avoid dropping it, or
allowing it to fall or tip over.

Adjusting the Divided Pickup
As string spacings vary with the model of the bass, the spacing between each of the coils in the
pickup must be adjusted to match the particular 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. 9–p. 12), and divide by one less
than the number of strings (i.e., in the case
of a four-string bass, divide by three).

Attaching the Divided Pickup
There are two ways to attach the divided pickup.
●
Attaching the Pickup with DoubleSided Tape (p. 9)
This provides the simplest way to attach the
pickup to flat-top basses.
* Do not place any unnecessary strain on the cable connecting the pickup and the controller. This may result in breaking.
* Do not bend or twist the pickup. Use particular care when removing the pickup.
■
Attaching the Pickup with Double-Sided Tape
1.
You decide on the location in which to
install the pickup.
For a 4-string bass:
Attach the divided pickup so that the center
marker is between strings 2 (D) and 3 (A),
the 2nd string marker is directly below string
1 (G), and the 5th string marker is directly
below string 4 (E).
(Viewed from above)
fig.1060ae
(Viewed from the neck)
fig.1060be
2nd string marker
* 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 GKcompatible device.

●
Attaching the Pickup with Screws (p. 12)
This method features the benefit of allowing
the pickups to be finely adjusted later on, but
it is somewhat difficult to carry out.
For a 5-string bass:
Attach the divided pickup so that the center
marker is between strings 2 (D) and 3 (A),
the 2nd string marker is directly below string
1 (G), and the 5th string marker is directly
below string 4 (E).
fig.1070e
* 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.
String

For a 6-string bass:
Attach the divided pickup so that the center
marker is between strings 3 (D) and 4 (A),
the 2nd string marker is directly below string
2 (G), and the 5th string marker is directly
below string 5 (E).

Page 10
Attaching the GK-3B to the Bass
* The divided pickup must be installed in the correct
orientation. Make sure that the cable from the
divided pickup is extending from the bridge side.
* When mounting the pickup on a left-handed bass,
orient the pickup with the cable extending towards
the neck.
fig.1090e
Bridge
* Install the divided pickup close to the bridge. In any
case, do not install the pickup more than 50 mm
away from the bridge.
fig.1100e
When you have decided on the location in which to
install the pickup, use pencil or tape to mark that
location.
2.
Tune each string to its normal tuning,
maximum 50 mm
and then be sure the neck curvature
and string height are set properly.
Any adjustments to the neck bow or
string height should be done at this point.
* Changes in the string height following installation
of the divided pickup may cause the clearance
between the strings and the pickup to change, which
can result in poorer sensitivity.
3.
Adjust the height of the pickup.
Insert the supplied spacers under the
pickup until it is at the required height
(do not remove the backing from the tape
yet).
There are three types of pickup spacers,
“A” (3 mm), “B” (1 mm) and “C” (0.25
mm); combine these as necessary to
achieve the proper pickup height.
* The pickup height should be set so that the clearance
between the strings and the pickup is approximately
1.5 mm (0.6”) when the top and bottom strings are
pressed at the highest fret. Adjust the number of
spacers while confirming the clearance with the
included (1.5 mm thickness) clearance gauge (p. 12).
* If the top and bottom string heights differ greatly
when the highest fret is fingered, compensate by
adding the appropriate half-length or one-third
length spacers until the clearance for both strings is
the same.
* When using an arch-top bass, put the pickup
cushions under the pickup spacers.
fig.1110e (Pickup Spacers)
Pickup
Spacer
Pickup
Cushion
* Adjust the pickup cushion thickness as required, for
example by using two pickup cushions.
* The pickup spacers and the pickup cushions are
attached to the bass with double–sided tape. When
affixing the tape, however, the tape’s thickness is
reduced by 0.1 mm (0.004”) when the backing of the
tape is removed. Therefore, when using several
pickup spacers, take this fact into account and set the
height slightly higher to compensate.
4.
Remove the strings from the bass.
10
Page 11
Attaching the GK-3B to the Bass
5.
Remove the backing from the tapes for
the pickup cushion, the pickup
spacers, and the pickup, and carefully
attach the pickup to the bass.
* After affixing these items, press them so that the
items adhere firmly.
* Wipe off any dust that may be on the location to
which you're affixing the double-sided tape. If the
location is dusty or dirty, the double-sided tape may
not adhere sufficiently.
6.
Restring and tune the bass, then
carefully check the height of the
divided pickup once more.
Measure with the clearance gauge to
confirm that the clearances between the
pickup and the strings are approximately
1.5 mm (0.06”) when you press the top
and bottom strings at the highest fret,
then finish up by making sure that the
strings do not touch the pickup when you
play the bass.
Then attach the cord hook near the
bridge, and fasten the pickup cable in the
hook so that it does not lift up or touch
the strings.
fig.1115e
* Use care in handling the divided pickup; bending or
twisting it may cause breaking in the coil elements.
Carefully insert something thin and flat (like a table
knife) under the Pickup from the bottom string side,
then gently pry the pickup upwards.
fig.1120 (Removing the Pickup)
4) After removing the pickup, carefully
remove the double–sided tape from
the bottom of the pickup.
5) Adjust the height of the Pickup.
If you wish to add a spacer, first
completely remove the used double–
sided tape from the top surface of
the existing spacers, then add the
new spacer.
If you need to remove any spacers,
remove the necessary number of
spacers and completely remove the
remaining double–sided tape from
the top surface.
6) Attach a piece of the new double–sided
tape B to the bottom of the pickup.
fig.1130
Cord Hook
7.
Take the steps below if the height of
the divided pickup is not right.
1) Carefully examine the pickup in its
current state, and add a suitable
number of spacers if the pickup is
too low, or remove one or more
spacers if the pickup is too high.
2) Remove the strings from the bass.
3) Remove the divided pickup from the
bass.
7) Attach the pickup to the top of the
spacer that is applied to the bass side.
8) Restring and tune the bass, then
check the height of the Divided
Pickup again.
11
Page 12
Attaching the GK-3B to the Bass
* Afterwards, you will need to adjust the pickup sensitivity when connecting to GK devices. However, you may find that
the sensitivity level on the GK device is too high. In such instances, you may be able to correct the problem by widening
the clearance between the strings and the pickup. Carry out Steps 1 through 8 again to lower the Pickup height slightly.
How to Use the Clearance Gauge
The divided pickup height must be adjusted so that the clearance between each string and
the divided pickup is 1.5 mm (0.06”) when the highest fret is fingered.
The clearance gauge supplied with the GK-3B is 1.5 mm thick; place the gauge between the
strings and the divided pickup as shown in the figure below, then check and adjust the height.
fig.1190 (Clearance Gauge)
■
Attaching the Pickup with Screws
The steps for determining the position for
attaching the pickup and for checking the
height are exactly the same as when using
the double-sided tape. Refer to “Attaching
the Pickup with Double-Sided Tape” (p. 9).
* If mounting the GK-3B with screws, ensure a
minimum string clearance of 15.5 mm (0.6”) from the
body at the position where the pickup is positioned.
1.
Determine the position for attaching
the pickup. When you have determined
the positioning, mark the position of
the holes at each end of the pickup on
the bass’s body.
2.
Remove the strings from the bass.
3.
Using a drill or similar means, open
pilot holes where the attachment
screws are to go in.
* If the pilot holes are not made in the correct
positions, then the pickup will not be attached in the
correct position either. Use extra care when drilling
the pilot holes.
* Make the pilot holes approximately 2 mm (0.08”) in
diameter.
* Drill pilot holes slightly more than 2 mm in diameter if
the bass body is made of a particularly hard material.
4.
Place the springs between the pilot
holes and the pickup as shown in the
figure below, then secure the pickup
with the screws.

5.
Restring and tune the bass.
6.
Adjust the height of the pickup.
* Adjust the mounting screws, loosening or tighten
them as required so that the clearance between the
strings and the pickup is approximately 1.5 mm
(0.06”) when the top and bottom strings are pressed
at the highest fret. Check the height using the
supplied clearance gauge (1.5 mm thickness).
* Afterwards, when connecting to GK devices, you
will need to adjust the pickup sensitivity again.
However, you may find that the sensitivity level on
the GK device is too high. In such instances, you
may be able to correct the problem by widening the
clearance between the strings and the pickup, so try
lowering the Pickup height slightly to see if this
approach is effective.
* If the springs are too long, use a pair of wire clippers
to cut them to the correct size.
Attaching the Controller
There are two ways to attach the controller.
●
Attaching the Controller Unit with
Holder (p. 14)
This allows the controller to be mounted
easily, with no modification of the body
required.
■
Adjusting the Length of the Pickup Cable
Place the controller where it is actually to be attached to the bass to check the pickup cable
length. If the cable is too long, wind it up in the space behind the controller.
fig.1160 (Adjusting the Pickup Cable Length)
●
Attaching the Controller Unit with
Double–Sided Tape and Screws (p. 18)
This allows the controller to be mounted at
any desired position on the bass, and
without the use of the holder, makes for a
thinner controller following installation.
However, it is somewhat difficult to carry
out.
13
Page 14
Attaching the GK-3B to the Bass
■
Attaching the Controller with the Holder
Refer to the following figures showing examples of ways to mount the controller, then select
the most suitable method for the bass at hand.
Installation Examples
Example 1) Mounting on the Front of the Bass
This method is recommended for basses
with sufficient space on the bass’s top to
mount the controller (p. 15).

* If Holder “C” makes contact with the strings and
interferes with performance, attach the controller
cushion to Holder “C” so as to lift Holder “C” away
from the instrument and prevent it from reaching
the strings.
* First, insert the controller cushion between the bass
and the holder, and determine a position that
ensures that none of the string vibration will be
disturbed. Then, affix the cushion.

1.
Place the controller in an appropriate
position on the bass surface to determine
where it is to be attached. Pay attention to
Secure the controller with the supplied
flat-head screw (3 x 16 mm).

the following points at this time.
• Install on a level surface.
• Position the controller so it does not
interfere with your playing.
• Position the controller so you can
comfortably operate the select switch, the
S1 and S2 switches, and other controls.
• Position the controller so that it does not

place undue strain on the normal pickup
input jack, divided pickup, or GK cable.
* Make sure that the plugs connected to the GK
connector and normal pickup input jack do not stick
out, as this may result in damage should undue
strain be placed on the GK connector or normal
pickup input jack.
2.
Once the controller position has been
determined, place the controller in
position and carefully drill a pilot hole
* If you’d rather not drill a hole in your bass, you can
secure the Controller using only the double-sided
tape or the holders. However, if only the doublesided tape is used to secure the unit, shocks from
rough handling during performances and from use
over an extended period will cause the tape to
deteriorate, with the GK-3B shifting out of position
as a result. Furthermore, if the finish on your bass is
less than perfect, you may discover that the finish is
also removed when you later remove the tape.
in the bass body where the controller’s
attachment hole is located.
* The diameter of the hole should be about 2 mm (0.08”).
* Confirm that there are no other problems in
attaching the controller before drilling the pilot hole.
3.
After attaching the double–sided tape
“A” to the underside of the Controller,
attach the controller to the bass.

How to Connect the GK-3B
* To prevent malfunction and/or damage to speakers
or other devices, always turn down the volume, and
turn off the power on all devices before making any
connections.
* When all devices are properly connected, turn on the
power to the various devices in the order specified
below. Turning on devices in the wrong order may
result in malfunction and/or damage to speakers and
other devices.
1.
Make sure that the power to the device
being connected is turned off, then
connect the device to the GK-3B’s GK
connector using the GK cable.
fig.2010
GK cable
GK IN
GK device
* The GK cable is a locking cable. When disconnecting
the cable, do not pull on it with undue force, but
instead release the lock and gently disconnect the
cable. You can disconnect the cable simply and
easily by holding down the locking portion with
your thumb and gently pulling on the plug.
fig.2020
* Before playing, be sure to wrap the cable around the
guitar strap near the end pin. This will prevent the
excess strain on the cable that can end up damaging
the bass or the GK-3B.
fig.2030
Connect the GK-3B 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.

How to Connect the GK-3B
2.
Use the included normal guitar cable
to connect the output jack on the bass
to the GK-3B’s normal pickup input
jack.
fig.2040e
Normal
Guitar Cable
* Connect using the included normal guitar cable or a
commercially available guitar cable.
Note that the use of connection cables that introduce
additional resistance may result in lower normal
bass volume.
* This connection is necessary not only for playing the
bass’s normal (straight) sound as well as the bass’s
straight sound mixed with the sound from the
connected GK device, but also for connecting the
bass’s ground and the GK-3B’s ground. Even if you
are not going to use the bass’s straight sound at all,
always make this connection because of the noise
reduction benefits it provides.
3.
Turn on the power to the connected
GK device.
The Power indicator on the controller
lights up. Now, when you play your bass
you’ll hear the sound of the connected
GK device.
* The power indicator lights up when the GK-3B and
the GK device are properly connected with a GK
cable and the power to the GK device is turned on.
943
* Always make sure to have the volume level turned
down before switching on power. Even with the
volume all the way down, you may still hear some
sound when the power is switched on, but this is
normal, and does not indicate a malfunction.
