Guide For Lowering The Action On Acoustic Guitar
This is a complete step-by-step guide for how to lower the action on an acoustic guitar.
This guide is divided into three parts i.e., adjusting the truss rod, nuts and the saddle. After adjusting all these three, you will get a comfortable sound from your guitar. So, make sure to follow each and every step to adjust your guitar action successfully.
steps for truss rod adjustment
The very first step is to evaluate the straightness of the guitar neck. Place your guitar at a plane area and examine the neck of your guitar. See if the neck is up bowed or back bowed.
The truss rod is a steel rod inside the peghead or the soundhole of a guitar. You can check where it lies in your guitar. It is used for correcting the up bowed and back bowed neck of the guitar.
You should also check whether your truss rod is one-way (which can only correct up bowed neck) or two-way (correcting both bowed and back bowed neck). Most probably, the truss rod will be two-way but still, it will be better to check it on Google by searching through the guitar model.
Use a screwdriver or any similar tool to adjust the truss rod. If the nut of the truss rod is too tight, then you can use a lubricant like some oil or vaseline to soften it. If your neck is up bowed, turn the rod screw to the right and if it is back bowed, then turn the screw to the left.
Turn the screw only ⅛ at a time and place a mark to know from where you have started. If you turn the screw more than ⅛ at a time, it will lead to a big change in the neck, making the situation worse.
Note: If your Truss Rod lies in the soundhole, then you will have to lose your strings first.
After turning the truss rod 1/8th to the left or the right, retune your guitar and check the guitar action. If it didn't get straightened enough, then give it one more ⅛ turn and then check the guitar action.
Remember to note the truss rod more than 1 time as it can damage your guitar.
Note: If you are a newbie, check the how to tune a guitar article while tuning your guitar, because tuning a guitar is not an easy job. Refer the guide once and re-tune your guitar like a pro.
steps to ADJUST THE ACTION AT THE NUT
Firstly, you need to measure the action at the first fret. You can do it by putting a feeler gauge at the first fret and make sure that feeler gauge just gets fit between fret and string.
Now, you can easily measure the action by using a ruler. If the action is 0.3 inches or 7.5mm then everything is fine. But if it is higher than 7.5mm then get ready to adjust the nut.
First of all you need a neck support for filing, then lose the sixth string to get it out of the nut. Don't damage the nut in this process. Now, file the nut through a nut file. Don't file the nut too much because you cannot undo this process.
When you think that you have filed the nut enough then place the string back, retune the guitar and see if the action has improved enough. If not, then file again.
Now, repeat this process with all the other five strings.
ADJUSTING THE ACTION AT THE BRIDGE/saddle
This is part of how to lower the action on an acoustic guitar bridge is an importance method to lowering the action of a guitar.
The saddle is also a nut which is positioned under the bridge to maintain the distance between fret and strings. If you have adjusted the nut then it is absolutely necessary to adjust the saddle too. Otherwise, you will not get quality sound from your guitar.
Start with measuring the distance between the sixth string and 12th fret using a ruler. Then measure the distance between the first string and 12th fret.
Now, if the distance between the 12th fret and the sixth string is more than 2.3mm or between the first string and 12th fret is more than 1.5 mm then you will have to lower it.
Strings are the one which keeps saddle at its place, so you will have to loose the strings first. You can loose the strings by using a string winder.
For getting the saddle out, you will have to remove the strings from the tuner. But you don't need to remove all the strings , removing just three strings will do the work.
Now, use a set of pliers to remove the saddle from the bridge. If the other three strings are interfering with this removing process, then you can take them off too. If the string seems dirty then clean the string like a pro before restringing.
Now take a piece of double-stick sandpaper and place it on a plane table. Then, sand down your saddle up to the point you want. Remember not to sand it too much as you will not be able to undo the process.
It will be best to sand the saddle only a little at a time.
Now, put the saddle back under the bridge. And put back all three strings which you removed earlier. Now retune your guitar and measure the action. If your action is still high, then you can repeat the process again.
Keep repeating this process until you don't get satisfied by the sound of your guitar.
Lowering the action on an acoustic guitar is not a very easy process. It requires the right knowledge and experience. One needs to be very cautious while performing this process. Otherwise, you can also damage your guitar completely.
