The LS-2 has six jacks.
To do what you want to do, hook it up like so:
In - (You bass)
Out - (To your amp)
Loop A Send (to dirt pedals)
Loop A Return (from dirt pedals)
Loop B Send (unused, or pedals that are bypassed)
Loop B Return (unused, or pedals that are bypassed)
Set the selector to A+B Mix, use the level knobs for each loop to blend clean loop with dirty loop.
I have pedals in both loops, because sometimes I like to blend say a fuzz with OD. Just turn all pedals in a loop off to make it a "clean" loop, or just don't use the loop at all, which automatically connects send to receive for that loop internally.
