If you aren’t certain if your action?needs adjusting or not?then read?on to learn when you need to change the action on an acoustic guitar.

You watching: Acoustic guitar action

This article will certainly talk around typical string heights however this doesn?t necessarily intend that you need to stick via these heights.

If you like a lower or better activity that is as much as you. You are just really limited by stress buzz (if you go too low) or a tough to play guitar and potential intonation concerns (if you go too high).

What is Action?

When activity on a guitar is referred to, it pretty much simply means just how high off the frets the strings sit.

A low action is when the strings are very cshed to the frets (compared to the normal) and also a high activity suggests that the strings are sitting high above the frets, compared to normal. You have the right to obtain some idea of what is taken into consideration normal in the just how to meacertain the action section listed below.

Normal isn?t necessarily ideal for you – some choose different actions for various reasons – but it provides you a starting point.

The action on your guitar is normally measured in 2 different areas – at the nut (or at the initially fret) and also at the bridge (typically measured at the 12th fret so rather much from the bridge really!)

What deserve to Causage your Action to Change?

Your action deserve to readjust over time for a couple of various factors.

Wearing of the saddle and nut

If the material of the nut or the saddle wears down, then your activity will gradually come to be reduced and reduced.

How quickly this will certainly happen will certainly depend on the product that your nut and saddle are made from. If it?s cheap plastic, then this will take place much quicker than it will certainly with the likes of bone or some of the brand-new synthesized bone equivalents (Nubone, Tusq, Corian etc).

If you are wanting your action lowered then this might sound prefer an excellent point – but tright here are 2 reasons that this isn?t the situation. Firstly, because your action is most likely to reduced unevenly across the strings and also secondly, bereason this will take a long time and also you want to get?your activity ideal as quickly as you can.

The solution? Good high quality nut and also saddle. Really good top quality nuts and also saddles will certainly last a life time. If you have actually already encountered this problem then you might need to replace the existing nut and also saddle. This isn?t primarily too expensive to do.

Warping of the Neck

The neck of your guitar can become warped as a result of humidity and also temperature transforms and also as a result of also much or not enough tension from the strings.


If your neck warps inwards (has also much relief)?- which might be as a result of strings that are putting as well much anxiety on the neck either because they are tuned as well tight or the guitar wasn?t designed to manage the gauge of strings you are using – or because of heat and also humidity – then the action?in the middle frets?of the guitar will come to be higher.

If your neck warps outwards (has actually back bow) -?which might be due to a absence of anxiety from strings or heat and humidity?-?then the activity at the nut finish and in the direction of the soundhole will come to be higher and also will certainly become lower in the middle frets.

The solution? Chances are you will certainly have to make a truss road adjustment to realign the neck. If this is something that has actually taken place quickly and also is due to somepoint you can control, choose string stress, then you should likewise make changes to proccasion it rearising.

Sinking or Swelling of the Top

If your top sinks (typically bereason of the humidity being as well low and your guitar drying out) then the strings will certainly become also close to the frets and also may cause worry buzz.

If your peak swells (generally bereason of the humidity being as well high and also your guitar getting also wet) then the strings will certainly be elevated also high above the fret-board and might reason intonation concerns and also a guitar that is challenging to play.

Check this before making any kind of adjustments to your activity – if you readjust your activity without first rectifying this issue then as soon as you do rectify this concern it will certainly be off aacquire. So depending upon whether your guitar is also dry or as well wet you may have to humidify or dry it out.

How to tell when your activity is as well low?

The biggest tell tale sign that your activity is as well low is the dreaded stress buzz!

If the strings are as well cshed to the frets then they will certainly vibrate against the frets which reasons that unwanted buzzing.

A lot of guitarists prefer to acquire their activity as low as feasible without gaining worry buzz. It?s a fine line. And if you go too low it?s tough to go earlier up without replacing parts. It?s less complicated to reduced than it is to raise.

You can likewise meacertain your action and compare it to the ?normal? below if you suspect your activity is also low.

How to tell once your action is as well high?

The best complaint that many guitarists have actually as soon as the activity is as well high is that it makes it even more difficult to play – more hard both in term of playing fluently without errors and also more tough physically.

It calls for more physical initiative to worry as soon as the action is high which means your playing is commonly sreduced and it is harder to acquire your playing smooth.

It will additionally be harder on your fingers ad wrist bereason you need to exert even more tension to play the notes. This will also be harder on the tips of your fingers.

The likes of barre chords are specifically hard for?a lot of?players as soon as the activity is high.

The various other point that a high activity can execute is affect your intonation. So if your intocountry is out this may additionally be due a high action.

If you suspect that your action is too high then you deserve to measure it and compare it to the standards below.

How to Measure the Action

To meacertain your action you will need feeler gauges. We are functioning in some tiny numbers right here. And fractions of a millimetre deserve to make a difference.

Feeler gauges are a selection of thin pieces of steel (be mindful the specifically thin ones can be quite sharp) of various thicknesses. Each ?blade? has a thickness composed on it.

Select the thickness that is cshed to what you are aiming for – for example you might pick a blade that is 0.26 inches (0.66mm) if you are measuring the height at the nut for the high E string (view below).

If as soon as placing the blade on peak of the fret there is still a gap then the gap is wider than the blade you have chosen. Choose the following blade up and also test that one.

If the string moves up once you slide the blade in then the gap is lower than the blade you are making use of. Choose the next blade dvery own and try again.

When you uncover the blade that will certainly slide on top of the fret and simply touch the string without noticeably relocating it up then that blade represents the height of the gap.

For the action at the bridge it is usually o.k. to use a ruler or specific string action?range – the gap is larger so the accuracy isn?t as tough to gain.

Action at the Bridge

The traditional heights of the Low E (6th) and also High E (1st) strings at the 12th fret are below. Because the low E requirements even more room to vibrate it needs to be better off the frets than the high E (or there will be stress buzz).

This is measured from the bottom of the string to the top of the 12th fret (top of the fret itself not the fretboard).

Low E – 3/32 inches (.094 inches, 2.38mm)

High E – 2/32 (.0625 inches, 1.58mm)

Action at the Nut

The ?standard? height of the action at the nut is 0.030 inches (0.76mm) for the low E string. Though tright here are certainly those that have different choices yet if you desire a starting point then 0.030 inches is mainly taken into consideration the conventional. However before, many players choose to go reduced than this.

This is measured from the bottom of the string to the top of the 1st stress.

The elevation of the other strings will certainly differ but the form of the nut takes treatment of this distinction and you don’t should worry around that unmuch less you are shaping a nut from scrape.

If your settings at the nut are also high and also you desire to reduced your action at the nut then inspect out my short article on just how to reduced the action at the nut end?


It?s really up to you whether you desire to readjust the action for yourself (you?ll have to learn a few points and will require some tools and also materials) or pay someone to carry out it.

The safest means is to get a expert to do it. But you deserve to conserve yourself some money, learn a new skill and have actually the satisfaction of doing it yourself as well.

If at all possible I would try this first on a cheaper guitar initially (if you have a greater finish guitar). Though if you are just adjusting the bridge or the nut, then it?s not the finish of the civilization if you get it wrong – worst pertains to worst you?ll have to gain brand-new ones – which is a pain and a bit of an expense yet not important. So it counts on your risk avariation.
