    bump! really need some advise
     
  3. I haven't seen this particular version before but it makes sense in a backwards, Japanese, early 60's, sort of way :)

    What they've done is put the bar after the nut so that, as the nut is tightened and the rod is pulled back through towards the back of the neck, it is bracing itself against the rear of the cavity. So what you are doing is essentially sliding the neck from the trussrod nut up, along the length of the trussod. Our version just lets the adjustment end of the rod float free but this works similiarly. It could have something to do with the fact that this neck appears to be shaped something like a set neck on an acoustic with the vertical support perpendicular to the fretboard (I don't know what it's called).

    Thanks J and Hambones.. i know TB is the place to go. Although i am not completly understand the explanation of Mr.Bone, shall i say that if i want to get the neck back to straight, i shall tighten the nuts which is going towards the turner side?
    Thanks again for all your help :)
     
  5. Yes, despite the weird look, I'm pretty sure this TR works like any other. You would tighten the nut on the rod to straighten the neck. It sure doesn't look like you could back it off any - that's a lot of overspray on the threads there!
