i've got a line 6 duoverb head and a few stompboxes along with it. The effects sound absolutely crap when plugged in straight to the input socket so i'm wondering if the effects loop socket is intended for that purpose?

If so how do i go by connecting it all up?
^^^ no. its like this>

guitar---->amp(effects send)--->pedals---->(effects return)

thats pretty much what i said. I guess I was just a little confusing on how I said it. Plug your guitar into the normal input on your amp, where you always plug it in. Then, on the back of your amp where it says effects loop send, hook that to the side of the pedal that says guitar in. On the side of the pedal that says to amp, hook that too effects loop return.
