I can tell you this as far as pitching goes: You need to get rid of the hissing.
I'm not trying to be critical of your demo - but if you're going to pitch in nashville you HAVE to get a pro demo. That's just the way it is - I don't like it...I think their attitude sucks. But its the way it is.
Evne if you just shell out $150 for a clean acoustic/guitar.
