Question Is it possible to set an individual volume per preset on the G-System Answer It is indeed possible: in the Preset Routing menu, you have two specific parameters called Left Output and Right Output. If you are connected in MONO, use Left output, and if you have a stereo or a dual amp setup, use both.  To access the parameters: 
  • Press EDIT
  • Press MENU
  • Search for Prst Routing menu with PAGE encoder, then ENTER
  • Adjust the parameters as needed. the values go from -100 dB (output mute) to 0dB = maximum level.
