I think what is meant by 9 and 3 is that the dial for the fx loop send is in the 9 o'clock position and the dial for the return is in the 3 o'clock position. That is how I have mine set and it works great, if you do it the other way I think you will overload the input of the EPSi and it will sound fuzzy.

9 o'clock looks like the red arm here:
clock image 9:00

and 3 o'clock looks like the red arm here:
clock image 3:00

I hope I don't sound condescending, if you already knew this then you have my apologies.



I have that pack and I like the ALN-BLU T1 live mixes (usually live modern), and I like both the scumback T1 live mixes (again, usually live modern).

Also, I would just load the stereo set, if you run mono it only uses one side, but stereo is always available if you need it (the 'c' firmware doesn't create a stereo from mono like it does for the reverb firmware according to the manual).
