Just a note from a rookie guitar tech...
If you do feel your truss rod needs adjustment (and you've mustered the courage to do so) I always think in these terms;
Tighening the rod (turning clockwise) works against your string tension and will arch the neck back lowering your action.
Lossening the rod (counter clockwise) bows the neck because it allows the string tension pull the neck forward.
Ok now the huge disclaimer.
Dont try this unless you KNOW it needs to be done.
Get a pro to do it if at all possible.
Do it 1/4 turn then tune up....check it...repeat if needed.
Different makes might work very different than what I have discribed above.
Check out the link provided by Hodge so you know what your shooting for.....not just guessing. Its not just about low action....relief is required.
Dont check your neck using a straight edge without strings being on and properly tensioned. That being said.....once you have tensioned strings they are perfectly straight...use them your guide. Straight edges can scratch!
The opinions expressed above are solely those of the writer who assumes no responsiblity etc etc .
ps. Get a pro to do it ;-)
