ROLAND GK-3B
Owner's Manual

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. *

*

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.

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.

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, 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.

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.

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).

4. Remove the strings from the bass.
