A truss rod is a metal bar (usually made from steel or graphite) that reinforces the cervix of a guitar, bass, or other stringed instruments. When tuned upward to pitch, the strings volition put several hundred pounds of pressure on the cervix –more than enough to bend it. A truss rod's task is to annul that tension and allow the actor to adjust how much (or how little) the neck bows.
There are two kinds of truss rods: unmarried action and dual-activeness. A single-action truss rod is only threaded on one cease, only dual-action truss rods are threaded on both ends. Threading both ends allows the truss rod to increase or decrease cervix relief before running out of adjustment. Adjusting the threads on the end of a truss rod counteracts the tension of the strings and volition increase or decrease the altitude between the strings and the frets depending on which fashion y'all turn it.
Before you begin, you'll want to ensure yous have all the necessary tools and enough space to do a safe and accurate setup.

However, if you are not sure of the proper tool or wrench size, consult your Owner's Transmission or contact the manufacturer to avoid the take chances of damaging your musical instrument.
The list below is a great reference, but don't forget the about of import tools of all; your eyes and ears.
- Phillips/ Large Flathead Screwdriver or Spanner Wrench

The first step in whatever setup is to look at the cervix and come across what correction we may need to make. By sighting the neck, we understand how the cervix reacts to the string tension and truss rod relief. At this point, we're just trying to become an agreement of whether the cervix is directly or not.
- Tune the guitar to pitch.
- Turn the guitar on its side, close one eye, and look down the neck from the headstock towards the bridge (left).
- Wait down the contour of the fretboard on both the bass and treble sides of the cervix. Is the neck straight, or is in that location a curve?
