icic...it seems that i've reached the limit of the truss rod tightness, the instructions says the truss rod shouldn't be too tight that it might break...thanks for ya suggestion
dude it's best to send to an experienced luthier to fix your neck issue if you're not sure.If it's overtighten,you mite just snap the neck into 2.Btw is it bowed forward or backward?String or fret buzz?
