Chapter 5 Creating Original Effects Types (Customize)
With the GS-10’s Customize function, you can rely on your
own sensibilities and create a totally new effect by tweaking
the settings for the “Preamp/Speaker Simulator,”
“Overdrive/Distortion,” and “Pedal Wah.” The result can
then be saved on the GS-10 as “Custom” settings.
You can also use these custom settings in other patches.

Customizing the COSM Amps

You can make three different sets of settings, Custom 1,
Custom 2, and Custom 3.
* The sound of any patch that uses Custom 1, 2, or 3 will be
altered if the custom settings are edited.
1. Press the PREAMP/SPEAKER On/Off switch to display
the PREAMP/SPEAKER effect screen.
2. Press PARAMETER [ ] [ ] to call up the Type
parameter.
3. Rotate the PATCH/VALUE dial to call up “Custom 1,”
“Custom 2,” or “Custom 3.”
