I have been messing around with trying different effects using the Line6 Edit program with a MKII shortboard connected to my Spider IV 75. I noticed it's not possible to have both flanger and phaser effects engaged at the same time. Which really sucks if you're trying to nail that VanHalen type sound. Both of these are available effects for FX-2 only and only 1 can be used at the same time? Is there any way to use both other than adding an external flanger or phaser pedal?
