Easy repair for various simple guitar problems (eg. buzzing sounds, constantly breaking string).
There are several guitar problems that you can fix quite easily on your own. Here are descriptions of some common guitar problem and ways to fix them that you may like to try before taking your guitar to be repaired by a professional.
Problem: My Strings Keep Breaking!!
The first thing you'll want to check is if your guitar is tuned too high. If you can't tell just by listening, try using a pitch pipe, tuning fork or an electronic guitar tuner.
You should also make sure that you are not causing the problem by playing your guitar too hard.
Problem: My Guitar Keeps Making Buzzing/Rattling Noises!!
The first thing to do if your guitar rattles is to turn your guitar face down (soundhole towards the ground) and shake it to make sure nothing has fallen inside (if it has, you should try to make it fall out the soundhole).
If you guitar buzzes, there are sereral things you can check. First make sure that the loose ends of your strings are not vibrating against the tuning pegs. If they are, bend them out of the way. Another thing to do is to check each string individually to see if they buzz (or sound dead). This may mean the winding is broken. If this is the case, you'll want to replace all of your strings. If *all* of the strings are buzzing, check to make sure your guitar is not tuned too low (again, you can use a tuning pipe, fork, etc. if you have trouble discerning the correct sound by ear.) If retuning doesn't solve your problem (never tune a guitar too high to keep it from buzzing--this may damage your guitar), you may want to try using a heavier set of strings. Another possible cause of buzzing sounds may be your bridge. If it is an adjustable bridge, try raising it slightly.
Problem: My Guitar Won't Stay in Tune!!
If your guitar keeps going out of tune, you may be playing too hard--try playing more softly to see if the problem continues.
You may also want to try stretching your strings. You can do this by using your thumb to push the middle part of the string across the other strings several times and then re-tuning.
If the guitar only seems out-of-tune when you are playing on the higher frets, your bridge may be placed incorrectly. The distance between the bridge and the 12th fret should be the same as the distance from the 12th fret to the nut. If your bridge is adjustable, move it to the correct position.
If you suspect your problems may be caused by overly worn frets or a twisted or warped guitar neck (this can cause buzzing and tuning problems) take your guitar to a professional, or someon who knows what they are doing, to get it fixed.
