I am just mostly trying to use a tube screamer and compressor, noise gate in the pod along with my dark terror. I love the sounds it has. But nothing seem to work, I have tried putting the pod hd in the fx loop and still getting no distortion from the tube amp, tried putting it after the tube amp and same problem, and tried sending on of the output of the pod to the return in the tube amp and still no distortion from the tube amp.
