So, what you guys are saying is that you trn it clockwise for the neck to go : \\/ (Inwards toward body)

And counterclockwise for the neck to go like : /\\ (outwards from body)

Correct me if I'm wrong so I can edit the post.

Junior, I've done it millions of times, and now you've even got me confused!! hahahaha![xx(]

Ok, if you tighten (clockwise) the truss rod, the headstock will go back and the strings will come down towards the finger board. If you loosen the rod (counter clockwise)it releases tension on the rod and lets the headstock lift, and also lifts the strings.

Better? geez, I hope so!![:p]

Oh, almost forgot to mention, adjusting truss rods can be a tricky business. Go REALLY easy when doing this. Only 1/4 turn at time, max. If the rod binds be careful. You may either be at the end of the thread or it's too tight in the slot. On some cheaper guitars, I've seen it where fingerboard glue also glued the rod. Yeah, I've been able to break it loose, but you have to be really careful when giving it the jam. Some cheaper rods seem to have threads that were cut with a pocket knife...you'll turn fine for a half turn, then it'll bind, or some silly thing like that.

Unfortunately it's very much a 'feel thing'. No guaranteed recipe for success...if in doubt, take it to a tech. Spend the money. If you wreck that rod, peeling a fingerboard off is a messy business...been there done that.

So, to answer your original question, clockwise. Just out of curiosity, what gauge of string do you have on there?

Here is a bit better truss rod tutorial.

Before you start twisting away be sure you are clear what you are trying to accomplish.  Tightening the rod (clockwise turn)will reduce the relief in the neck.  Or another way to look at it, will reduce the distance from the strings to the fretboard, in the middle of the board.  A counter clockwise turn will reduce the tension of the rod and allow a bit more bow and add relief to the neck.

Ditto zeroroaster.  Go slowly, 1/4 turn at a time then let the guitar settle for several hours before you decide if furhter adjustments are needed.

wqbusch, Welcome, I see you're getting plenty of good advice, trust me these guys know. If I may add one other thing you may want to keep in mind,,,, If you are wanting to change the action (string hight) you DON'T do this with the truss rod. The proper way to do that is tweaking the saddle and nut. There is much misunderstanding on this issue, but the truss rod is NOT an action adjustment, so be careful or you'll get a lot of buzzing.

Thanks for the info.  When I turn the nut counter clockwise it gets harder to turn.  When I turn it clockwise it gets looser.  Something seems wrong

I think the terms loosen and tighten are confusing you. Let those two words go and think of it like this: Counter-clockwise = increases the relief. Clockwise = flattens out the relief. But keep in mind, you have to have some relief or you'll get some buzzing.

You've probably turned it too much. 1/8 of a turn, then it needs time to settle in. You've probably lost your starting point now.

A lil.. Thanks man. I think that before I start screwing with things, I'll try a heavier guage..

Do i need to de-tune when I adjust the rod?

The rest of yeah, you made my head explode. . LOL

Ryan, as Rocket and others pointed out,,, Go with small incremental changes, you won't put to much extra tension on the strings that way, but make sure you re-tune AFTER the adjustment settles in and BEFORE you make any new measurements.
