    Please dont feel stupid. this forum is exactly the right place for you to ask such questions.

    The truss rod is a long steel bar wich goes through the neck of the bass. It keeps the wood from getting warped or bowing from the pressure of 4+ strings tightened on it. Some high-end basses have two truss rods in the neck. It (they) can be adjusted with an allen wrench, usually where the neck and the body meet.

    When and why would I need to adjust it?

    When the neck of your bass is "bowed" out(i.e. warping), then it may be time to adjust the rod. I am sure this isn't a complete answer though.

    You need the truss rod to adjust the relief in the neck. Zero relief means that your neck is pefectly flat - adding relief can help to remove fret buzzing and can be used in conjunction with the bridge saddles to get the right setup to suit your playing style.

    The relief will also affect the tension on the strings to a certain extent and the overall feel. I have been told by the pro set up technician at the Bass Centre in London, that having very little relief means that the strings feel tighter higher up the neck (closer to the bridge) but easier to play closer to the nut and that the opposite is true for setups with more relief.

    I'm not entirely convinced by this and find that on most basses I prefer zero relief and low action as advocated by Anthony Jackson on the Bass Player website.
