it's important to keep in mind that adjusting the trustor on guitar is not for inexperienced guitarists you should probably have about two or three years of playing experience before you try to dress the truss round of your guitar because it can be a dangerous procedure and then for your guitar it can cause serious damage that can cost a lot of money to fix so make sure that you know enough about your guitar and you're very careful when you perform this procedure before you start yeah today we're going to learn how to adjust the truss rod on a guitar every guitar has a truss rod and it's used to counteract the tension of the strings on the neck to keep it relatively flat and it's used to correct warp in the neck and there are pretty much three kinds of work that you can have a guitar neck there can be a backwards boat which will essentially put the strings all the way against the frets didn't read a lot of buzzing there's a flat neck you'll still probably get a lot of buzzing because as you go up the neck pushing down on the string will press the strings against the frets and you'll get buzzing and a forward bow which can make the guitar harder to play or you'll get no buzzing so the first step in deciding whether your guitar needs a truss rod adjustment is place your finger on the first fret and the 14th fret of the g string of the guitar and then you look at the guitar around the sixth fret and you should see a gap between the g string which will be lower than all the other strings because you're pressing on it and the fret if you don't get meet you there at a backwards bow or a flat neck and speaking the way you probably want to adjust your truss rod and so if you do have a backwards bow or just a flat neck then you'll want to loosen your truss rod because loosening your truss rod allows the strings to put our attention on the guitar neck and pull it forward into a more of a forward bow so once you've determined whether your guitar needs a truss rod adjustment you'll then locate the nut of the truss rod in this case it's located under the fretboard inside the sound hole this isn't the case with every acoustic guitar but you can see it right here on mine and so what what you want to do is take the allen wrench and put it in the nut of the truss rod and once you do that I you will turn it in my case counterclockwise because I'm trying to correct a flat neck but you want to be really careful when you do this step you don't want to turn that not more than a quarter of a turn each time the excessive turning can damage the guitar and once you do a quarter of a turn you will want to let your guitar sit for about ten maybe fifteen minutes just to let the neck settle and get ready for the next quarter turn if it's required that's how you do it yeah I just lighter than yours I feel like I should just one you just what
