So i'm sitting here doing some truss rod adjusments. Nothing major, but after about 1/8 of a turn, i notice that it gets VERY easy to turn to the left.

It seems that i'm not turning the truss rod, just the nut.
So my question is, am i just turning the nut, or am i turning the truss rod?becuse its not getting any straighter.
I'm so confused.
Please help
Craig
