I am recording some dry guitar tracks tonight and am getting more hiss than I want when going back through the pod. I have a les paul going straight into an avalon 737 then into the mixer. I am coming out of an aux, balenced, into a radial JDI then unbalenced into the pod. The pod then back into the mixer. I am just getting too much hiss on the pod sound. Am I doing something wrong? Any thoughts?
