When I play for a performances with a band I use my Pod XT Live with a Spider IV 75 watt with the my pod xt live. So I wanted to start just bringing my pod with out the amp. So I plugged in my pod xt to my guitar and from the pod to a dirext box witch is connected to the house system. When I plugged it in and started playing my Crunch and distortion sound it sounded bad, terrible, squeaky, and over distorted. It didn't sound bad when I plugged it in to my amp on a clean setting on my amp and a distortion or cruch sound on my pod. What is wrong and how do I fix it. I need to get a answer as soon as possible
