What is a truss rod?
A truss rod is a metal bar that has been inserted into the neck of the guitar. It runs the full length of the guitar's neck. Its purpose is to counteract the tension created by the strings of the guitar. A truss rod can be adjusted to compensate for movement within the guitar caused by seasonal changes and humidity levels. Most guitar brands use this system.
