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

adjustments made with knobs other than [MASTER] are

* Do not turn off the power while making the settings. This may 

corrupt the settings already stored in the VGA-3. Always be 
sure to exit from GK Setup mode before turning off the power.

* When you have finished GK Setup, press [TUNER] once more.

* There is no prescribed sequence for the GK Setup settings. 

You are free to set only the parameters needed.
