The guitar is an instrument which has a unique impact on the personality of its player. Once you start strumming the guitar, you are enthused with new found excitement and a sense of distinct identity. Therefore the instrument goes a long way in uplifting your self image. However, any instrument which makes music is bound to have intricate components which work in tandem with each other when you play. A thorough awareness of the mechanisms is therefore essential to handle it properly. You need to have a working knowledge on the guitar setup neck, how to change the strings etc, which prove to be very crucial from time to time.
Before attempting to setup the neck adjustments on your guitar, first you need to tune it properly and also set the correct pitch for it. Then your instrument is ready for neck adjustments. The most important aspect of adjusting the guitar neck is to know how to deal with the truss road. The truss rod is the key component of the guitar neck. The neck setup depends on whether you tighten or loosen it. There may be two situations to handle; either the neck is under bowed or it is over bowed. If the former condition is prevalent, you need to tighten the truss rod for correcting it. If the latter condition exists, then the frets would be very close to the neck and you will be able to spot a hump like structure on the neck. Correct this by loosening the truss rod.
In most acoustic guitars the truss rod is located right underneath the neck just where is meets the sound hole. In order to tighten or loosen it, you might have to take the help of pliers or wrenches. Such adjustments on the guitar setup neck are impossible to perform by hand. For example, if you are tightening the rod, you should do so till you actually feel the tightening, that would surely require a lot of effort.
Once you're apparently done with neck adjustments, you need to cross check. At first you need to retune your instrument once again. After that, compare the neck to the alignment of the strings to check if it's actually straighter than what it was. The straighter the neck, the lower the action and the easier it is to play.
