																	A truss rod is a thin metal shaft that runs the length of the guitar s neck from the nut to the heel where the neck joins the body. 
																	It sits just under the fretboard and can be accessed through a small hole behind the nut on most guitars which is usually covered by a small piece of wood or plastic held down by screws. 
																	Some are non adjustable but most modern truss rods have a nut at one or both ends that adjusts its tension. 
																	While classical guitars do not often feature truss rods due to a lack of tension on the guitar itself due to the nylon strings things are changing and it is becoming more common.
