Hey guys... I've been playing for about 8 months on my father's old takamine acoustic (from my limited knowledge it's a pretty nice guitar.) Anyways, today I was practicing for a few hours and everything was fine... Just strumming away with my thumb... I left for a little while to take a break and after I started playing again I noticed that the guitar seemed to be a little out of tune.. I assumed the tensioners got turned while the guitar was on my bed.. I attempted to tune it by ear, as my electric tuner wasn't around, and I spent almost half an hour and couldn't quite get it right.. Finally I noticed that the guitar itself was slowly loosening tension on the strings.. I looked at the neck to see if it was bending, but I couldn't find anything wrong with it (of course, I only know a little about how a guitar should line up.) So now here I sit b/c guitar center is closed.. I took the strings off and started to attempt to adjust the truss rod, but all the information on that is centered around adjusting the action..

So.. If anyone could throw a suggestion or two at me about what it could be that'd be great..

Also, when I got the guitar I had a full setup done on it from a highly recommended tech.. It's been gravy to play up until now!:(
