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.

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.

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.
