Of Tubes and Tones: The Only Guitar Tone Guide You'll Ever Need


Every guitarist wants great tone, but what if you’re not entirely sure what that means? Guitar teacher Noel S. breaks down the basics of guitar tone and shares what every electric guitarist should know about their gear…

We’ve all heard great classic guitar tones from our favorite musicians and felt motivated to hit the practice room or visit the music store, determined to achieve the same results. Finding a way to achieve those results, we’re faced with the infinite choices of strings, pickups, amps, tone settings, and effects, which leaves us looking for additional knowledge of how mastering guitar tone all works.

It’s easy enough to get creative with imagery-based tone descriptions like “warm,” “bright,” “mellow,” “harsh,” “clean,” “dirty” and so on, but many guitarists feel frustrated by the subjective nature of these types of descriptions. For students who want clear pathways to the guitar tones they love, we require definite terms to communicate those elements which produce guitar tone.

So, to enhance your knowledge of guitar tone, check out the following terms to know, gear to experiment with, and musicians to listen to as you embark on your path to becoming the guitarist you’ve always aspired to be.

What is the Tone of a Guitar?

The guitar tone is the sound that a guitar makes when it is played. It can be described as the guitar’s voice. The tone of a guitar depends on many factors, such as:

  • The type of guitar
  • The strings
  • The pickups
  • The amplifier 

Each of these factors contributes to the overall tone of the guitar. Want to learn more about guitar tone and why it matters? Be sure to sign up for guitar lessons! This will give you the best idea of how to improve your guitar tone. You’ll also learn things like what you see in the video below:

Why is Guitar Tone Important?

Any guitar player worth their salt knows that guitar tone is important. After all, the tone of your guitar is what determines how your music will sound. 

A good guitar tone can make your music sound full and rich, while a poor guitar tone can make it sound thin and tinny or even give you a dry guitar tone quality. That’s why it’s so important to take the time to find the right guitar tone for your music. 

Luckily, there are a few things you can do to help ensure that you get the best guitar tone possible. 

First, be sure to use high-quality strings on your guitar. 

Second, invest in a good amplifier. 

And third, practice regularly. 

By taking these steps, you’ll be well on your way to achieving the perfect guitar tone for your music.

Guitar Tone Terms to Know

The type of guitar is perhaps the most important factor in determining the tone. Different types of guitars have different tonal characteristics. 

For example, an acoustic guitar has a brighter, fuller sound, while an electric guitar has a heavier, more distorted sound. The strings also play a role in the tone of the guitar. 

Different types of strings have different tonal qualities. Nylon strings have a smoother sound, while metal strings have a sharper sound. The pickups are another important factor in determining the guitar tone. Pickups (which are located under the strings) convert the vibrations of the strings into electrical signals, which are then amplified by an amplifier. 

Different types of pickups produce different tones. For example, single-coil pickups have a brighter sound, while humbucker pickups have a heavier sound. The amplifier is also an important factor in determining the guitar tone. Different amplifiers have different tonal qualities, too.

If you’re a guitar player, it’s important to have a basic understanding of guitar tone terms. This will help you communicate with other guitarists and get the sound you want out of your instrument. Here are some essential guitar tone terms to know


Any note you pluck on the guitar is heard as a “pitch,” defined as the fundamental cycle-per-second sound vibration produced (typically measured in units called “Hertz” or “Hz”). Say you played an A note on the 5th string open. The whole string vibrates at 110 cycles per second to produce the fundamental note – its lowest vibration speed for the note that you’re playing. That is the pitch of A that you hear.


Your A string is also vibrating in halves, creating a sound that’s called an “overtone.” This doubling of vibration speed produces the first overtone, heard at the same time one octave higher.

Your A string vibrates in thirds as well – three equal pieces, producing the second overtone. Even higher divisions of string vibration occur at the same time you pluck, and as the number of divisions goes higher, the less audible the sound of that overtone is.

As a side note, understanding vibration speed explains why the first guitar string is called “high E,” even though it’s located lower (physically speaking) than the other strings. It is also why moving “up” the guitar neck is a sideways and downward movement.


Play that A string again, this time stop only that string’s vibration. You will discover that the D string is also vibrating a little bit, because of the overtones contained in that fundamental A noted you plucked.  You’ll hear it as “A1,” or the same note sounded as if the D string were plucked at the 19th fret.

The human ear hears only the fundamental A as the defined pitch, but it hears those overtones as what is called “timbre” or “tone.”  That allows us to hear which instrument or voice has sounded the fundamental note. Your ear takes in the sound of the fundamental note, plus all the overtones, then your brain recombines this information into a perception of tone.


A fundamental note contains energy that moves with a specific frequency, categorized into ranges, or bands, known as “bass,” “middle” and “treble.” Frequencies ranging from 20 Hz to 300 Hz receive their regulation from your amplifier’s bass control knob.

Pluck your low E string, and adjust your bass knob from zero to 10. Then, perform the same experiment with your high E string, noticing that low E changes considerably, while the high E string doesn’t. That’s because your high E string is tuned to a standard 329.63 Hz above the range for bass frequencies.


The best frequency range for human hearing is the midrange: 300 to 4000 Hz. Most human vocal sounds are produced in this range, which explains why our hearing tunes in to sounds in this band of frequencies. This fact reveals one cool way you can help create sonic space for your band’s singer, by omitting notes in your guitar chords that would crowd his or her midrange-frequency space. Note that most of our guitar’s fundamental range falls within the midrange, and we can set that control higher than our bass and treble.


Finally, treble encompasses sounds from 4000 Hz to 20,000 Hz. Remember our definition of tone? Sound vibrations known as overtones are generated by a string moving in halves, thirds and continuously smaller divisions, with audibility diminishing and disappearing after the seventh division.

So, high-string riffs from above the 12th fret can have a consistent and dynamic level, great tone and well-balanced audibility, provided you keep the treble or presence knob on your amp from venturing far beyond the midpoint. The pain from hearing too much treble will let you know when to back off.

Guitar Tone and Gear

In order for you to gain confident knowledge of the guitar sound you want, it’s important to know the following descriptions of tone controls, amplifiers, pickups and effects pedals. As you experiment with these sounds, be sure to listen to guitarists who have used these effects in their music.

How Guitar Amps Effect Tone

An amplifier’s true tone needs to be measured at power inputs of at least 30% volume, and then measured again at 50% and beyond. The tone descriptions below follow those standards of measurement, and differences in tone between tube amps and solid state amps emerge only within those categories.

Tube Amps

Transformers on a tube amplifier provide a natural, high-frequency gate that keeps a guitarist’s high-note overtones in check, which is a desirable quality. When the amp warms up, and the transformer reaches a point of core saturation, tube amplifiers deliver a level of compression to the tone, evening out the dynamics of the guitar sound during performance. This reduces the chance of a note sounding like it was plucked too hard, too softly, or with an abrupt attack. It provides a more sustained dynamic level of loudness, another desirable quality for guitar tone.

Fourth overtone harmonics are produced by tube amps, and the interval produced by this tone delivers more sustain to the fundamental note. For examples of tube amp sounds, listen to Deep Purple’s “Smoke on the Water” intro. You can also check out Stevie Ray Vaughan recordings, such as “Crossfire,” “Voodoo Child,” and “Pride and Joy.” Want to hear more? Try Steve Vai or Angus Young’s recordings.

Solid State Amps

The sharper sound wave generated by these amps provides for a more sudden “attack” portion of your tone. The overtone primarily produced by these amps, the 3rd harmonic, provides for a quicker decay of the sound. These characteristics lend themselves very well to a precise attack of each note – an instant response. Listen to B.B. King’s “King of the Blues” solo for an example of a solid state amp sound. Or, check out guitar recordings from Andy Summers of The Police, such as “Every Breath You Take.”

Stack Amps

Since the guitar tone effects from amplifiers present their most desirable qualities with the volume turned up to a certain amount, guitarists require these amps only for performances in very large venues. Smaller amplifiers provide better tone conditions for recording and practicing, and restaurant, bar or club performances.

My experience performing up and down the New York City andNew Jersey coastline started with a solid state Polytone Amplifier. I needed more volume for every venue where the band performed, so I got rid of it and bought a used Roland Jazz Chorus 120, which sounded great at low and high volumes. I’ve performed with it for decades and never spent another cent maintaining the Roland.

How Guitar Pickups Affect Tone

Guitar pickups effect tone to the extent that some effects pedals now feature settings with a design for each type. Every pickup takes physical variations in acoustic sound energy and converts them to electric sound energy. The materials used and the way that they’re used makes the difference in tone.

A  pickup affects guitar tone in many ways, such as the strength of its magnetic field, size of its magnetic field, diameter of the wire wrapped around the magnet, its location on the guitar body, and how the guitarist is playing. When choosing a pickup, keep in mind the range of frequencies you’d like to emphasize in your tone, the abruptness or subtlety you’d prefer in a sound’s attack, and the dynamic curve in your sound’s sustain and decay. Discover these points by experimenting with this information and listening to examples of guitarists playing different types of pickups.

Piezo Pickups

Piezo pickups use quartz crystals to receive and transmit sound energy. They’re mounted in the saddle bridge of guitars that use them. The very accurate dynamic response to a guitarist’s string displacement (how hard you pluck) surprises people upon first trying Piezo pickups. That’s why everyone who uses them also uses a compression effect to even out the dynamics.

On a related note, string displacement affects tone, too! A downward displacement of 45 degrees toward the soundboard or body is the goal I always recommend to students. Compare that tone to a sideways pluck and also an upward pluck (away from the soundboard or body). In each case, we take note of how all of these parameters affect the presentation of our overtones, our note’s attack, sustain and decay. These are the important factors in determining the guitar tone we want.

Listen to Jesse Cook perform “Mario Takes a Walk” and also Sting’s recording of “Fragile” to hear good examples of the Piezo pickup tone.

Single Coil Pickups

Your plucked guitar string sends sound vibration into the magnetic field, emanating from copper wire coiled around a magnet, which makes up the single coil pickup. This results in the vibration of the magnetic field, as well. When the magnetic field is in flux from this vibration, an electrical signal is generated and amplified though your amp.

The field of magnetism produced by the single coil pickup covers a smaller area than the field of magnetism from Humbucker pickups. A smaller range of harmonics (overtones) are captured from a smaller field of magnetism, providing for less low and midrange-frequency overtones. This results in the single coil pickups generating a tone that occupies a tonal space in the higher midrange; giving the tone a clearly audible presence for the listener. Check out Yngwie Malmsteen and Eric Clapton to hear single coil pickup recordings.

Humbucker Pickups

Humbucker pickups are designed to provided the answer for the single coil’s tendency to pick up surrounding electromagnetic fields and accompany the guitar’s tone with an annoying “hum” sound. Two magnets were used in Humbuckers to cancel out extraneous electromagnetic hum noise.

Since a larger field of magnetism captures a greater range of middle and low-frequency overtones, Humbucker’s put out more of the lower midrange of tonal space. This sound is very desirable, especially for riffs or chords using the lower strings. Listen to Jimmy Page and Led Zeppelin perform “Rock and Roll”.

Effects Pedals and Your Guitar Tone

There are many different types of effects pedals on the market, and all of them are designed to alter the tone of your guitar. Check out a great guide to the main types of effects pedals on

The order of adding effects and using effects pedals generates from common sense and practical experience. Place the wah pedal before your compressor to obtain a more abrupt attack to your sound, or after the compressor to provide a more subtle attack and a lower and middle-frequency boost.

To even out your dynamics before adding effects, you can place the compressor at the beginning of the effects chain. A distortion pedal adds overtones, so place it before the equalizer so that you can control those added tones.

Phasers and flangers add a slightly delayed or out-of-phase sine wave to your original sound, which is something you wouldn’t want to add a lot of overtones from your distortion pedal to. Put these types of effects after the distortion and EQ. 

Look at the descriptions of your reverb/delay sounds. You will see words like “large hall,” “small hall,” “dome,” “tunnel,” and “studio.” What would my tone sound like if I were playing guitar in one of these locations? That’s why we want our total tone package in place before adding these effects.

What is a True Tone Guitar?

A guitar’s tone is determined by a number of factors, including the type of wood used, the pickups, the strings, and the amplifier. 

However, one of the most important factors in determining tone is the guitar’s bridge. The bridge is responsible for transferring the vibrations of the strings to the guitar’s body, and it can have a significant impact on the guitar’s sound. 

True Tone guitars are equipped with a unique bridge that is designed to maximize tone and sustain. The bridge itself is made from a special alloy that is tuned to create a richer, fuller sound. In addition, the bridge is significantly wider than traditional bridges, which allows it to transfer more vibrations to the guitar’s body. 

As a result, True Tone guitars are capable of producing a wide range of sounds, from warm and mellow tones to bright and agile tones. Whether you’re looking for a guitar with a rich and full sound or a guitar with an extensive range of tones, a True Tone guitar may be just what you’re looking for.

What is a Whole Tone Scale Guitar?

A guitar tone is the overall sound of a guitar, which encompasses everything from the type of guitar to the way it is played. 

The whole tone scale guitar is a type of guitar that is known for its unique sound. 

This guitar has a scale that is made up of only whole tones, which gives it a very distinctive sound. Whole tone scale guitars are typically used in jazz and blues music, and they are known for their smooth, mellow sound. 

Do Guitar Tone Woods Matter?

One of the most frequently debated topics among guitarists is whether or not guitar tonewoods matter. 

On one side of the debate, there are those who believe that the type of wood used to construct a guitar has a significant impact on its tone. They argue that different woods have unique sonic properties that can be heard when the guitar is played. 

On the other side of the debate, there are those who believe that guitar tone woods are overrated. They contend that the type of wood used is less important than other factors, such as the guitar’s pickups and strings. 

Ultimately, there is no definitive answer to this debate. While some guitarists swear by the importance of tone woods, others find that they make little difference. The best way to determine whether or not they matter is to experiment with different woods and see what sounds best to you.

What is a Good Guitar Tone?

Guitar tone is the sound produced by a guitar. It is most often described in terms of timbre, tone quality, or tonal character. Good guitar tone generally refers to a pleasing, balanced sound with a full range of frequencies. When troubleshooting guitar tone problems, it is important to consider all aspects of the guitar signal chain, from the strings to the amplifier. 

A good starting point is to make sure that all the guitar’s parts are in good working order and that the instrument is properly set up. Once that is taken care of, there are many different ways to achieve a good guitar tone. 

Some guitarists prefer to use pedals and effects to shape their sound, while others rely on their amp and guitar settings to create the desired tone. Ultimately, it is up to each individual player to experiment and find what works best for them.

If you are looking for a guitar with a unique tone, then a whole tone scale guitar might be the perfect option for you.

Using the science, recorded examples and your own experimentation, keep on improving your guitar tone. We can achieve a lot more than we ever thought possible with great improvements in sound quality!
