Ah thank you, that is good to know. It sometimes blinks and sometimes does not.. anyway it is definitely an unstable setup.
My goal is a double tracked guitar sound live. I used to do it with hardware; A guitar with dual outputs (neck and bridge pickups) running into two amp rigs.
On the duo I was going to split the mono guitar signal, send one through the fractal doubler 100% wet, the other 100% dry and run each to separate amp simulators.
It sounds ok using the gxamplifier but jcm800pre is very nice
