I recently pulled the trigger on the Line 6 Pod HD 500 only because I got a GOOD price $375. This thing is way over my head tech wise. I need some one to point me in the right direction for help on learning what all the buttons & knob are for & how do I download the newer software upgrades. The Pilot's Handbook that comes with it isn't much help. I've been looking around the web for help and the Line 6 website but not found what I'm looking for. Any tips would REALLY be appreciated.
