Are you struggling to play your acoustic guitar comfortably? Does it feel like the strings are too high or too low? If so, your guitar may need a setup.
A properly set up guitar can make it easier to play chords and notes, improve tone and sustain, and prevent buzzing or fretting out.
In this article, you can learn how to adjust the truss rod, bridge height, saddle, and nut of your guitar, as well as how to choose the right tools and maintain your instrument over time.
Whether you are a newbie or an experienced player, investing some time in setting up your acoustic guitar can make a big difference in your playing experience. Let’s get started!
What exactly does ‘acoustic guitar setup’ mean?
The acoustic guitar setup means adjusting the components of the guitar to ensure that it is comfortable to play, sounds great, and stays in tune.
A proper acoustic guitar setup includes adjustments to the neck, truss rod, bridge height, and saddle.
Why new acoustic guitars need setting up
New acoustic guitars often require setting up because larger manufacturers may prioritize speed over a careful setup.
Also, guitars can be affected by changes in climate during storage and shipping, and they may also settle and change over time.
Getting a professional setup allows the instrument to be customized to your specific needs, ensuring it plays and sounds its best.
Factory Setback
You might be surprised that many guitar manufacturers cut corners and rush through their factory work, leading to poor-quality instruments that can frustrate and disappoint even the most talented players.
Some of the most common issues with factory setups include uneven frets, high action, poorly cut nuts and saddles, and necks that are not properly adjusted.
Even if a guitar looks great on the outside, it may have underlying issues that affect its playability and tone.
A good setup can make a world of difference in how your guitar feels and plays and can help you get the most out of your instrument.
Level of humidity
Humidity can significantly impact the setup of an acoustic guitar, as it can cause the wood to expand or contract, leading to changes in neck relief, action height, and intonation.
In a dry environment, the wood can shrink, causing the neck to bow and the action to become too low, resulting in buzzing strings and poor playability. On the other hand, in a humid environment, the wood can swell, making the neck curve upwards and the action too high, making it harder to play.
To avoid these problems, it’s essential to store your guitar in a controlled environment with stable humidity levels. A humidifier or dehumidifier can help regulate the moisture content of the air and prevent damage to your instrument.
The impact of transport and storage times
When you purchase a new acoustic guitar, it’s crucial to consider the transport and storage times that it has gone through.
Most budget instruments are made in the far east and have to travel by cargo ship for several weeks before reaching the UK. During this time, the guitar’s components can shift and move around, affecting its geometry and playability.
It’s also worth noting that the conditions in which the guitar is stored can also impact its overall condition.
As we already mention, the humidity and temperature changes can cause the guitar’s wood to expand or contract, leading to changes in the neck’s curvature or the saddle’s height.
Therefore, it’s important to inspect the guitar thoroughly upon arrival and make any necessary adjustments to ensure that it’s in optimal condition.
How do you know if your guitar needs a setup?
You know your guitar needs a setup if you feel uncomfortable while playing or notice issues such as intonation problems, buzzing, or sharp fret edges.
If you’re experiencing any issues with your instrument, it’s recommended to have your guitar set up by a professional.
However, if you’re confident in your abilities and have the necessary tools, you can attempt to set up your guitar yourself.
Just be sure to follow instructions carefully and make small adjustments while checking frequently to avoid causing damage to your instrument.
Mastering the setup: Complete guide to setting up your acoustic guitar
A properly set up acoustic guitar is essential for achieving optimal playability, tone, and overall performance.
In this guide, we will take you step-by-step through the process of setting up your acoustic guitar, covering crucial adjustments such as string action, intonation, truss rod, and more.
Unpack and inspect the guitar
Start with the body of the guitar and make sure there aren’t any visible cracks, scratches, or dents. Check the fretboard for any rough or uneven spots that could make playing uncomfortable.
Take a look at the tuning machines and make sure they’re securely fastened and turning smoothly. Don’t forget to inspect the bridge and saddle for any signs of damage or wear.
Once you’ve thoroughly inspected the guitar, it’s time to remove it from its packaging and give it a quick tune.
It’s important to loosen the strings before removing them to avoid any unnecessary stress on the neck.
Once the old strings are removed, take the opportunity to give the fretboard a quick clean with a soft cloth and some lemon oil.
Then, carefully install the new strings and tune the guitar to the standard pitch.
Congratulations, you’re now ready to start the setup process and make any necessary adjustments for optimal playability and sound quality.
Check string gauge and tune up
This ensures that you have the proper tension on the strings and that they are in tune with each other, which is essential for good sound quality and playability.
Start by checking the gauge of the strings that came with your guitar. If they’re not the gauge you prefer, now’s the time to switch them out. Make sure to use a trusted brand and size of strings to avoid any issues with tuning stability or intonation.
Once you have the right strings, use a tuner to get each string in tune. Check the tuning of each string several times, as the tension on the neck and bridge can affect the tuning.
Adjust the truss rod
The truss rod is an essential component of your guitar’s setup, as it provides stability and maintains the proper relief in the neck. To adjust the truss rod, you’ll need to remove the strings and loosen the nut located at the headstock.
Use the appropriate tool, such as an Allen wrench, to turn the truss rod in the desired direction. If your guitar has too much relief, turn the truss rod clockwise to straighten the neck. If your guitar has too little relief, turn the truss rod counterclockwise to add more relief.
Be sure to make small adjustments and check the relief frequently using a straightedge and feeler gauges.
Adjusting the truss rod should be done carefully and gradually to avoid causing damage to your guitar. It’s also important to keep in mind that changes in temperature and humidity can affect the neck’s relief over time, so regular adjustments may be necessary.
If you’re unsure about how to adjust the truss rod properly, it’s recommended to seek the help of a professional guitar technician.
By taking the time to adjust the truss rod and maintain the proper relief in your guitar’s neck, you can ensure optimal playability and sound quality for years to come.
Check for high frets
Make sure to check for high frets on your instrument, as they can cause buzzing and affect playability. To do this, you’ll need a fret rocker – a tool that helps you identify any high frets on the neck. Simply place the fret rocker over each fret and see if there is any rocking motion. If there is, the fret is too high and needs to be adjusted.
High frets can occur due to a variety of reasons, such as changes in temperature and humidity, or simply from the wear and tear of playing. If left unaddressed, they can cause buzzing, intonation issues, and even string breakage. However, by identifying and addressing high frets, you can ensure that your guitar plays smoothly and sounds its best.
Adjust nut height & String Slots
The nut is a small piece of material located at the top of the guitar’s fingerboard, where the strings rest before they reach the tuning pegs. It’s important to adjust the nut height so that the strings are not too high or too low, which can cause intonation problems and make it difficult to play.
To adjust the nut height, use a set of feeler gauges to measure the distance between the bottom of the strings and the top of the frets at the first fret. This distance should be around 0.4-0.5mm for the bass strings and 0.2-0.3mm for the treble strings.
If the nut height is too high, it can be filed down slightly using a nut file until the correct height is achieved. If the nut slots are too deep, causing the strings to buzz or rattle, they can be filled with a small piece of bone or plastic and re-filed to the correct depth.
Another important aspect of nut adjustment is the string slots. These should be cut to the correct depth and width for each string to ensure proper spacing and intonation.
The slots should be slightly wider than the string to allow for easy tuning and should be cut to a depth that allows the string to rest just above the first fret. To check the slot depth, press down on the string at the third fret and check the distance between the string and the first fret.
If the string is too high, the slot may need to be deepened slightly.
If it is too low, the slot may need to be filled and re-cut to the correct depth. Adjusting the nut height and string slots can make a significant difference in the playability and tone of your guitar.
Check saddle curvature
The saddle is the small piece of material that sits on top of the bridge and holds the strings in place. It needs to be curved in two directions to ensure that each string vibrates at the correct length and produces the right pitch.
To check the saddle curvature, you can use a special tool called a radius gauge, which has a curve that matches the average curvature of most guitar necks. If the saddle doesn’t match the radius gauge, you’ll need to adjust its shape by sanding it down or building it up with a shim.
This can be a delicate process, so it’s important to take your time and make small adjustments until the saddle matches the correct curvature. By doing so, you’ll ensure that your guitar produces accurate intonation and a balanced sound across all strings.
Set action by adjusting saddle height
You’ll want to adjust the saddle height to set the action for your playing style to achieve optimal playability and tone. The action, or the gap between the strings and frets, is a crucial aspect of guitar setup, and can greatly affect how easy or difficult it is to play, as well as the sound quality.
By adjusting the saddle height, you can fine-tune the action to suit your preferences and playing style. Whether you prefer a lower action for faster playing or a slightly higher action for more sustain and clarity, you can achieve the desired action height with a little patience and attention to detail.
To adjust the saddle height, you’ll need to remove the strings and carefully sand down the bottom of the saddle to lower the action, or add a shim or replace the saddle to raise the action. It’s important to measure the action at various points along the neck using a string action gauge and feeler gauges.
Make small adjustments as needed, checking frequently to ensure you achieve the desired action height. Keep in mind that a lower action may cause some buzzing or rattling if played too hard, while a higher action may require more finger strength but can provide better tone and sustain.
Check pickup response
If you’re planning on using your guitar for live performances or recording, it’s important to check the pickup response to ensure that your sound is clear and consistent. This involves plugging your guitar into an amplifier or recording device and playing a few notes to see if the signal is being picked up properly.
If you notice any distortion, feedback, or inconsistency in volume, it may be a sign that your pickups need adjusting. To adjust the pickup response, you can either raise or lower the pickups using the screws on either side of the pickup. Raising the pickups will increase the volume and treble response, while lowering them will produce a mellower tone with less volume.
It’s important to make small adjustments and test the sound frequently until you achieve the desired tone. Additionally, you may want to adjust the pole pieces on your pickups to balance the volume and tone of each string. By taking the time to check and adjust your pickup response, you can ensure that your guitar sounds its best in any situation.
Conclusion
Setting up your acoustic guitar is vital in maximizing its playability, tone, and overall performance. By understanding and implementing adjustments such as string action, intonation, and truss rod adjustments, you can tailor your instrument to suit your playing style and preferences.
Remember, a well-set-up acoustic guitar not only feels more comfortable to play but also produces a more balanced and pleasing sound. So, invest some time and effort into setting up your acoustic guitar, and enjoy the rewarding results that come with a finely tuned instrument.
