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.

String
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, and divide by one less than the number of strings (i.e., in
the case of a four-string bass, divide by three).
2.
Loosen the screws (2) in the sides of the pickup, move the
markers so that they are correctly positioned according to the
distance between the strings, then retighten the screws.
4.
In order to position the center marker as shown in the following
figure, attach the divided pickup with the 2nd string marker and
5th string marker directly under the specified strings.
For a four-string bass (1G–4E):
For a six-string bass (1C–6B):
For a five-string bass (1G–5B):
1.
Attach the divided pickup so that the screws on the side of the
pickup face toward the neck.
2.
Make sure that the divided pickup and the bridge are no more
than 50 mm apart (15–25 mm is recommended).
3.
Adjust the height of the divided pickup so that there is
approximately 1.5 mm of clearance between the string and
pickup when the string is pressed on the highest fret.
*
Be careful not to tighten the screws excessively.
*
This adjustment made so that both 2nd string marker and 5th string
marker are at the same position.

For Bass Signal Wiring
1. Do not exceed 12 Vp-p for input signal level.
2. Solder uncovered wire (silver) to the earth (ground) of the bass.
3. Solder the white wire to the bass signals.

For Switch, LED Wiring
(Select Switch, DOWN/S1 Switch, UP/S2 Switch, LED)
1. Ground wire for each wiring is common.
Do wiring as “Wiring Diagram (*1).”
* Do not take power source from this circuit except for LED.
2. Using a toggle switch of 1 pole ON-OFF-ON momentary

Thank you for purchasing the Roland GK-KIT-BG, a divided pickup kit. The GK-KIT-BG is a specialized kit for internal
installation of the included bass divided pickup. Installing the components in the bass allows the bass to be used with
GK-compatible devices for bass.
Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES.”
These sections provide important information concerning the proper operation of the unit. To ensure proper installa-
tion – which is critical – and operation, please read this owner’s manual carefully. The Owner’s manual should be
saved and kept on hand as a convenient reference.
IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY,” please read and observe the following:
Roland assumes no liability concerning any damage to
the bass and GK-KIT-BG upon installing the GK-KIT-
BG. Please proceed with the installation using cation
and care at your own risk.
402
Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
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 mal-
functions.
901
To avoid the risk of damage to internal components that
can be caused by static electricity, please be careful
whenever you handle or store the board.
To properly drive the GK-compatible device for bass
with the GK-KIT-BG, you must adjust the height of the
Divided Pickup and the sensitivity of the GK-compatible
device for bass. Be sure to make these adjustments cor-
rectly, in accordance with this manual and the owner’s
manual for the GK-compatible device for bass.
Be sure to use the special cable supplied by us to connect
the GK-KIT-BG to the GK-compatible device for bass.
Use of any other cable may cause unnecessary problems.
To avoid damage, be sure there is no unnecessary strain
on the cables.
Never bend, twist or otherwise place undue pressure on
the Pickup. Be especially careful when removing it. Also,
make sure no force is applied to the yokes.
Make sure the power to the GK-compatible device for
bass is off when connecting GK-KIT-BG and the GK-
compatible device for bass.
GK-KIT-BG cannot be used with basses that have
unusual or customized string setups, or basses strung
with nylon, rubber, or other non-metallic strings.
