The GK-3 is a special divided pickup, which,
when installed on an ordinary guitar, allows
you to use the guitar to play the sounds of
GK-compatible guitar devices (Roland GR-
20 or VG-88 etc.).
•The pickup’s adjustable curve mechanism
makes the GK-3 compatible with guitars
with different fingerboard (string) curves.
• Included with the GK-3 are special
holders, spacers, and other accessories,
which allow you to easily attach the unit
to any of a wide variety of guitar models.
• You can use the controller switches to
control the various functions of
connected GK devices.
