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.
Place the included adjustment template
over the third and fourth string yokes,
and turn the R adjustment screw to adjust
the coil height.
The adjustment template features slits for
setting “250R” and “300R” curves. If the
curve for your guitar is “250R,” adjust the
yoke at “250R” so that the yoke is at the
same height as the template’s surface. If a
curve of 300R is used, adjust the yoke at
“300R” so that the yoke is at the same
height as the template’s surface.
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 curve for your guitar differs from any
of these settings, first adjust the settings to
the nearest position that best matches your
guitar, then fine-adjust the settings after
installation of the pickup is completed.
* 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.
