IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, please read and observe the following:
Power Supply
•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
•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.
•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.
•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.
•To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or other moisture.
Maintenance
•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.
•Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.
Additional Precautions
•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.
•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.
•To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels (especially when it is late at night).
•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.
*When turning the bass with GK-2B upsidedown, 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.
*When turning the bass with GK-2B upsidedown, handle with care to avoid dropping it, or allowing it to fall or tip over.

●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.

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.
