Is the NS/Stick's truss rod bidirectional like the Stick's?

My NS has developed a concave bow in the neck, and I can't seem to find any amount of tightening or loosening that will straighten it out. In fact, if I loosen it too much, the truss rod simply starts to protrude from the back of the neck. What can I do to straighten the neck?
Thanks in advance,

If it is bowed,tighten the truss a couple of Flats on the NUt at a time--
wait a few minutes-re tune-if it is still bowed-tighten by one or two flats of the truss nut-re tune-wait a couple minutes-tighten it till it buzzes the frets-now back off the tension carefully till it stops fretting out-re tune...
Works for me....

Sorry, "a couple flats on the nut"? Where is this nut on the NS? I only know about the adjustment at the top of the neck, and that doesn't have flats.
Thanks,

I think Micheal misunderstood your question, you are saying you have "backbow" even with the truss adjusted loose? Don't recall seeing any NS Sticks with a nut with flats in it, only at the top that uses an Allen wrench. If you have backbow, tightening the truss will make it worse. Any chance the bolts holding the neck to the body are loose? Seems odd you would get the truss sticking out from backbow without hitting the body, especially with a graphite neck, unless you have a wooden neck like mine. Might be something to send back to SE, that doesn't sound right. Can you provide pics?

If the adjustment is an allen Wrench,observe the flat parts of the wrench and count the turns-that is What I meant by 'The Flats"--just a way of tracking how much adjustment you are making--sorry if you didn't understand that-on a Nut,you count the flats as you turn.
If the instrument is BOWED{think Bow and Arrow-get it?}(toward the strings,action real high off the board)you must tighten to straighten the neck.If the neck is "ARCHED"{the opposite of a Bow} toward the truss rod,strings fretting out and buzzing-you must loosen it.
Is this easier to understand?

Like that term "Arched" better, I've often heard the term "backbow" used.

A little more help - just noticed something on my NS as I have daylight coming through this morning that highlighted something I missed last night. My neck is set up just the way I like it, with a tiny amount of bow present. When I look at the back of the neck, the truss does protrude out a little around the middle of the neck. If we are talking the same amount, it's probably normal. If I look at the backside of my NS, I'd swear it's arched, but looking at it from fretside, I'm fine.

Tip: Schubb capos work well on an NS. Put one at the first fret, then hold a string down around the 17th fret and check the relief in the middle. You probably will get a different picture than looking at the backside, I sure do with mine. Make sure the capo is just on the fret so the string lays as flat as possible on the fret.

In contrast, on the backside of my Grand the truss protrudes a bit at the bridge end.

Thank you both! I cranked my truss rod further down than I thought possible, and the neck has straightened out.
