Nope!
They are either "ALL ON" or "ALL OFF"!!!!
But......I'm playing mine out through the FX Return of an EVH 5153 (50 watt head) w/ the cab modeling "ALL ON" & loving it. I run through the PA too! It takes a lot of Rig tweaking to get it to work for both applications & the guitar speakers really matter, but it can be done!!!!!
Good luck w/ all of this too!

PS - This is a HUGE FLAW in the 11R for sure though!!!!
They really needed to make it so that these could be seperated.
