I had seen some people doing this (CAB at the end). The sound seems to be different. Just as the volume changes. Looking at the manual, on page 59, I can create a new signal chaining, but I would have to use IN2 (Fx RTN). So, I would have to duplicate the signal out of my guitar ... But I think that, when returning to the signal chaining where the CAB is, the sound will be added. Right? This is crazy ... hehehe. Anyway, doing as you were told, implies changing the parameters that I had already done. If you have any images, this will help.
Thanks for support. Any tip is welcome.
I had the Ultra (2010), but I was standing in the studio ... I never used it live. Sorry my english
