Line 6 DL4 MkII – Factory Reset

How to Restore DL4 MkII Factory Presets

DL4 MkII is pre-programmed with a set of great factory presets at birth, containing six unique settings accessible from presets A through F. Whenever you perform a preset save, all the factory presets will be over-written with your new custom settings. 

Perform a Factory Restore when you want to erase the sounds currently saved in any of the preset locations and restore the original factory presets.

  1. Press and hold both the A and TAP footswitches while connecting the power adapter to the DC IN. 
  2. Continue holding the switches for about 10 seconds, or until you see the green LEDs light up.
  3. Your DL4 MkII device is now restored with all factory presets as well as the original default global settings.
