I have exactly the same experience! Is there any comment of line6?
Did line6 do changes at newer models? Because my old G30 is still running perfect. An I have both now here, old and new and can compare them.
I guess it's thing of taste and adjustment. And Strat is not Strat.
But I dial another body in Workbench and everything is fine for me again.
First is the orig. v2.0, second is my body changed.
