Also it might be useful to edit the global EQ of the Pod Go to cut out any unwanted low or high frequences. My Pod Go sounded fine from the start, so no problems, but editing the global EQ did help quite a bit with the tones I could get out of it. I got the details from this short video - I would take a note of your global EQ settings first in case you want to return to default or just create a back up using the Pod Go menu before changing the global EQ. It's just two settings your changing so it's simple.
