Attaching the GK-3 to the Guitar
Adjusting the Divided Pickup
The surface of a guitar’s fingerboard is not flat, but describes a large arc from the first string to
the sixth string, and the strings themselves are laid out in roughly the same curved
arrangement. The divided pickup uses independent coils to pick up the vibrations of each
separate string, so variations in the clearance between the strings and their corresponding
pickups may result in discrepancies in sensitivity for each string. The GK-3’s divided pickup
features a mechanism that allows you to adjust the curve outlined by the pickups, making the
GK-3 compatible with different types of guitars.
1. Check the curve of the fingerboard on the
guitar to which the GK-3 is to be attached.
* Refer to the guitar manual or catalog, or consult the
guitar manufacturer.
* If you are not sure of your guitar’s curve, attach the
pickup to the guitar with the yokes left in the
lowered position, then adjust the yokes after the
pickup has been installed.
2. Adjust the pickups with the supplied
screwdriver.
When completely extended (i.e., with the
adjustment screw turned fully clockwise),
the yoke is set to approximately 184R;
when the yoke is in the fully lowered
position, the setting is approximately 400R.
If the guitar has a fingerboard curve with
a value such as 250R or 300R, first adjust
the yoke so that the yoke height is
approximately midway between the fully
extended and lowered positions, then
adjust to the optimal positions after the
pickup is installed.
* Be sure not to turn the adjustment screw too much.
When raising the yoke, rotate the adjustment screw
slowly clockwise, and stop turning the screw at the
point where you feel further resistance. Continuing
to turn the screw beyond this point may result in
damage to the unit.

Attaching the Divided Pickup
There are three ways to attach the divided pickup.
● Attaching the Pickup with Double-
Sided Tape (p. 9)
This provides the simplest way to attach the
pickup to flat-top guitars.
● 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.
● Attaching the Pickup with the Pickup
Holder (p. 13)
This is the simplest method for guitars with
the bridge mounted on posts embedded in
the guitar body.
* 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.
