nasty fretbuzz on first few frets

i've got some nasty fretbuzz happening on the first few frets. the truss rod isnt moving any bit either, its totally jammed. so what can i do now?
dont have any half decent luthier/tech guy around here so i have to fix it by myself. its a great cheapo bass but i have to fix this issue, please help

 

i have worked on by basses before and i know when and how to adjust the truss rod. anyway,
the nut isnt cut too low really, its way lower on my geddy lee but that doesnt have this buzz and the the frets are not sticking out either. i think the neck is too straight.
its buzzing a lot more on the lower two strings as they are "looser" and have less tension thus more freedom to buzz around i guess

 

yeah it needs to be loosed but its not budging either ways at all, its totally jammed. raising the bridge saddle only raises the string height and the buzz remains unless i raise it way too much and make it difficult to play. am thinking about getting higher gauge stiffer strings
