If I am plugging into the gt-10, then the gt-10 into the effects return of my Carvin, will it hurt anything if I just leave it at that setup instead of the 4 cable method? I remember reading something in an old tube amp'ss manual that if doing this, I have to plug a lone cable into the send and let it dangle, regardless if its being used or not. Or...something to that effect. Anyways, any thoughts?
