I recently purchased a 3ch Dual Rectifier. Before this, I was using a POD X3 Live for my amp modeling and effects. I was hoping that when I got my Dual Rec, I could just use the Pod for effects and bypass the amp modeling. But when I hook it up to the amp, it sounds like crap and there's a bad hissing sound. Am I doing something wrong? Should I plug the Pod in the front or in the fx loop? Help would be appreciated
