Settings for the GK Pickup (GK Setup)

The tonal character of the VGA-3 (COSM Guitar) is greatly affected by how the divided pickup is installed.

You need to enter the appropriate GK pickup settings (GK Setup) so as to minimize any tonal inconsistency that might arise from differences in how the divided pickup is installed.

Be sure to redo the settings when you switch to a different guitar.

Preparations for using the GK Pickup

Attaching the GK-2A to your guitar

First, attach the GK-2A divided pickup (optional) to your guitar.

To learn how, refer to the owner's manual for the GK-2A.

The GK-2A cannot be used with the following types of guitar. (When attached to one of these guitars, the GK-2A will not function correctly.)

Guitars with unconventional string structures, such as twelve-string guitars or pedal steel guitars

Guitars that use nylon or gut strings

Bass guitars

Other guitars that, for structural reasons, have no location where the GK-2A divided pickup can be attached correctly
