Ever since when i started playing guitar some 15 years ago i was told never touch the truss rod. But now Im wondering what in gods name does it do. As i get older i like to know how to do it myself. Now i have searched online for some basic ideas but none of them seem to explain how and why to adjust it. Im getting buzz from the 1-4th fret and i have heard that to fix it you must relieve tension on the neck. So basically im looking for a guide on how to tell wheather or not the neck requires adjustment and how much i would have to give it.
thanks again
