i currently have the xx-7 hooked up to a bunch of guitar pedals using 
the external sends.. now, i'm using insert cables... the ones where 
it's a 1/4 plug that goes out through the tip and comes back into via 
the ring... now since most of the pedals i'm using are mono inputs, 
does that mean that if i only have one insert going out of each 
external sub output (left) that the returning signal will only come 
back on the left channel?
