Adjusting The Divided Pickup - Roland GK-3B Owner's Manual

Attaching the GK-3B to the Bass

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).

Measure the distance
between these two strings.
Example: a distance of 57 mm
57 divided by (4-1) = 19 mm
A gauge with pitches of 16, 17, 18, and 19
mm is printed on the GK-3B package, and
you can also determine the spacing by
placing this gauge against your bass.

2. Use the included screwdriver to loosen
the screws, move the markers to the
position of the appropriate distance
between each string, and tighten the
screws.
* Be careful not to tighten the screws excessively.

* This adjustment made so that both markers are at
the same position.
* Be careful when moving the markers; do not use
excessive force.
Be especially careful with those at both sides of the
markers.
