Bass guitar with low action

The action height, or the distance between the strings and the fretboard, is a crucial element that can make or break your playing experience.

It affects everything from your ability to effortlessly navigate the frets to the very essence of your bass guitar's sonic character.

In this article, we'll delve into the intricacies of action height, exploring its impact on playability and tonal quality.

We'll guide you through the factors that influence this critical setting, empowering you to make informed decisions.

Whether you prefer a low action for lightning-fast runs or a medium action for a balance between comfort and sustain, we've got you covered.

What is action height on a bass guitar?

Action height refers to the distance between the strings and the fretboard of your bass guitar. It is commonly measured at specific points, such as the 12th fret or the saddle.

This seemingly simple measurement holds great significance as it directly impacts your playing comfort and the way your instrument produces sound.

What components of the bass guitar affect the action height?

Several factors come into play when determining the ideal action height for your bass guitar. Let's take a closer look at them:

  1. Bridge design: The type of bridge on your bass, whether it's a vintage-style bridge, a modern bridge with individual saddles, or a floating bridge, can influence the adjustability and range of action height settings.

  2. Truss rod adjustment: The truss rod is a metal rod running through the neck of your bass guitar, responsible for counteracting the tension from the strings. Correctly adjusting the truss rod can help achieve a proper neck relief, ultimately impacting the action height.

  3. String gauge: The gauge of the strings you use can affect the tension they exert on the neck and subsequently impact the action height. Lighter gauge strings may exert less tension, resulting in lower action, while heavier gauge strings may necessitate a higher action to prevent buzzing.

What different types of action can you have on your bass guitar?

Understanding the variations in action height can help you determine the right balance for your playing style and preferences. Here are some common types:

  1. High action: A higher action generally refers to greater distance between the strings and the fretboard. It can offer more room for aggressive playing, reducing the chances of string buzzing. However, it may require more finger strength and can be less comfortable for those who prefer a lighter touch.

  2. Low action: Lower action means the strings are closer to the fretboard. This setup allows for easier fretting, faster playing, and a lighter touch. It's often favored by bassists who require quick, nimble fingerwork. However, low action may increase the risk of string buzzing, particularly with heavy playing or if the bass is not set up properly.

  3. Medium action: As the name suggests, medium action falls somewhere between high and low. It offers a balanced compromise, providing reasonable playability and a good balance of tone. It's a popular choice among bassists who seek versatility and a comfortable playing experience.

Now that we've scratched the surface of understanding action height, you're well-equipped to explore its impact on your bass guitar's playability and tone.

In the next section, we'll delve deeper into the effects of action height.

How does action height impact your bass guitar's playability and tone?

When it comes to your bass guitar, action height is more than just a mere measurement. It wields a significant influence on both the playability and tonal quality of your instrument.

In this section, we'll explore the profound impact that action height has on your bass guitar experience. Get ready to discover how this crucial setting can transform your playing.


  • Fretting ease: The action height directly affects how easily you can press down on the strings to produce clear notes. A lower action allows for smoother and quicker fretting, making complex basslines and speedy runs a breeze. On the other hand, a higher action provides more resistance, requiring a stronger finger grip and potentially slowing down your playing.

  • Bending and vibrato: If you love to incorporate expressive techniques like string bending and vibrato into your bass playing, the action height becomes even more crucial. A lower action allows for effortless bending and enhanced control over pitch variations, enabling you to infuse your playing with emotion and flair.

  • Speed and dexterity: For those seeking lightning-fast playing, action height plays a vital role. A lower action minimizes the distance your fingers need to travel between strings and frets, facilitating rapid movements and enhancing your overall speed and dexterity on the instrument.

Tonal quality:

  • Sustain and resonance: The action height affects the amount of string vibration and contact with the frets. A lower action can result in increased sustain and resonance, allowing your bass notes to ring out for longer and producing a fuller, more vibrant sound. Conversely, a higher action may reduce sustain and dampen the overall resonance of your bass.

  • String vibration: The proximity of the strings to the fretboard impacts the way they vibrate. A lower action encourages greater string-to-fret contact, enhancing the transfer of energy and resulting in a more focused and powerful tone. Conversely, a higher action can lead to a more "open" sound, with slightly less string-to-fret interaction.

  • String buzz: Achieving the optimal action height is essential for avoiding unwanted string buzz. A well-balanced action ensures that the strings have just enough clearance over the frets to prevent buzzing, while still maintaining comfortable playability. Excessive buzzing can detract from the clarity and definition of your basslines.

By now, you're starting to realise the significant impact that action height can have on your bass guitar's playability and tonal character. As we continue our exploration, we'll guide you towards finding the ideal action height that suits your playing style and preferences.
