Fender MUSTANG GT40 Owner's Manual page 6

Based on customer feedback, Mustang GT now includes options for disabling the Looper and Quick Access
modes of the MGT-4 Footswitch—providing simplified use for live performance.
To select and use these footswitch options, press the MENU utility button and use the ENCODER to scroll to
and select the "FOOTSWITCH" menu option:
Use the ENCODER to scroll to and select "MGT-4 (4-BUTTON)":
Use the ENCODER to scroll to and select "LOOPER ON" or "QA ON" ("on" in a green box is the default setting
for both):
Press ENCODER to turn selected feature off, on which its box will turn red. Sequential presses of the MGT-4
footswitch MODE switch will now skip any functions disabled in this manner:
When footswitch option selection is completed, press the MENU utility button to return to the active preset.
