September 25, 2023


Mastering the art of equalizing (EQ) guitars is a foundational skill in the music production landscape. Whether you're working with a mellow acoustic number or a roaring electric guitar riff, understanding how to shape your guitar tone using EQ can elevate your sound to professional standards. In this comprehensive guide, we walk you through nuanced approaches and tips to EQ guitars for a polished, vibrant sound.

The Fundamentals of Guitar Frequency Spectrum

Guitars have a broad frequency range, typically spanning from 80 Hz to 5 kHz. To effectively EQ guitars, it’s vital to understand the role of different frequency bands. The lower range (80-200 Hz) governs the body and warmth, the midrange (200 Hz – 2 kHz) shapes the character, and the higher frequencies (above 2 kHz) add clarity and presence.

Crafting the Low End

The low end of a guitar, particularly in the 80-200 Hz range, holds the secret to a warm and full-bodied sound. However, too much emphasis here can lead to a muddy mix. Subtractive EQ, where you cut unwanted frequencies, is often a good starting point to avoid a boomy outcome, while maintaining the richness of the guitar.

Midrange: The Heart of the Guitar Tone

The midrange is where the guitar expresses its primary tonal character. Manipulating the mid-frequencies can help in achieving various textures; a boost around 300-500 Hz can add warmth, while a slight dip can prevent muddiness. Working in the 800 Hz – 2 kHz range can aid in bringing out the attack and articulation of the guitar, making it stand out in a mix.

Treble Frequencies for Brilliance and Clarity

The treble frequencies, typically above 2 kHz, are responsible for the brilliance and clarity of a guitar sound. A gentle boost in this region can lend a sparkling, airy quality to your guitar tracks. Be cautious though, as excessive boosting can lead to a harsh, piercing sound.

Taming Harsh Resonances

Guitars can sometimes exhibit harsh resonances, which are concentrated energy at specific frequencies. Identifying and reducing these frequencies using narrow EQ cuts can significantly clean up your guitar tone, allowing for a smoother and more pleasant sound.

Enhancing Acoustic Guitars

When it comes to the intricate process of EQing acoustic guitars, one of the foremost considerations is ensuring that the inherent, natural wooden resonance of the instrument remains intact and undistorted. This resonance is the very soul of an acoustic guitar and gives it its unique sound signature. A nuanced approach involves making subtle adjustments, such as a slight boost in the region around 200 Hz. This specific boost can infuse the guitar sound with a touch of warmth, giving it a fuller, richer texture. Conversely, by carving out a strategic notch around the 1 kHz mark, you can effectively reduce any boxy or muffled tones that sometimes plague recordings. Lastly, for that crystal clear, ethereal sound that many producers aim for, enhancing the high end with a delicate shelf EQ can bring forward a shimmering quality. This not only captures the subtle intricacies and overtones of the strings but also allows every nuance and detail of the acoustic guitar to stand out, making it truly shine in a mix.

EQing Electric Guitars: A Detailed Approach

When it comes to EQing electric guitars, understanding the instrument's frequency range and how it interacts within a mix is crucial. Electric guitars typically span a broad frequency spectrum, from the deep lows around 80 Hz to the sparkling highs up to 5 kHz. Start with a high-pass filter around 80 Hz to eliminate any unnecessary low-end rumble and ensure the guitar doesn't muddy the mix. The 100-200 Hz range provides the guitar's body and warmth; a slight boost here can enrich a thin-sounding guitar, but caution is needed to prevent overpowering bass instruments. The midrange, specifically between 300 Hz and 2 kHz, is the heart of the guitar's voice. Boosting around 400-800 Hz can add punch and presence, making the guitar more prominent in a mix, while cutting in this range can help in reducing muddiness. The upper mids, particularly the 1-2 kHz range, can emphasize the guitar's bite and attack. The higher frequencies, from 2 kHz to 5 kHz, bring out clarity and detail. A subtle boost here can add brilliance and airiness, but excessive boosting may result in a harsh sound. Finally, always be on the lookout for any unwanted resonances or overly sharp frequencies; a narrow Q (or bandwidth) cut can help in taming these. Periodic A/B testing with the bypassed signal ensures that your EQ adjustments are enhancing the guitar's tone. Lastly, always EQ in context: soloing the guitar might mislead, so ensure it sits well within the overall mix for a harmonious and balanced sound.

EQing Electric Guitars for Different Genres

Electric guitars, inherently versatile and adaptable, have been the backbone of many music genres for decades, each requiring its distinct tonal adjustments. Given this varied landscape, EQing these instruments demands a nuanced, genre-specific approach to ensure their tones resonate authentically with listeners. For genres like rock, where the guitar often drives the song's energy and emotion, a midrange boost is paramount. This amplification in the mid frequencies endows rock guitars with a characteristic gritty and robust character, reminiscent of the rebellious spirit and raw power of iconic rock anthems. On the contrary, jazz, a genre deeply rooted in improvisation and intricate melodies, necessitates a gentler, more refined guitar tone. Jazz guitarists often seek a velvety, warm backdrop for their melodic explorations. Achieving this often involves dialing back the sharper high frequencies to prevent any abrasive or jarring sounds, and simultaneously boosting the lower mids, enriching the tone with warmth and depth. This careful and deliberate EQing ensures that the electric guitar beautifully complements the delicate nuances of jazz compositions, allowing other instruments like the double bass or piano to meld harmoniously. In essence, understanding the EQ intricacies of electric guitars across genres is pivotal in ensuring the instrument's tone is both authentic and complementary to the musical narrative.

High-Pass and Low-Pass Filters: Cleaning Up the Sound

Incorporating high-pass filters can eliminate low-end rumble, offering a cleaner sound. Similarly, low-pass filters can curb the harshness in high frequencies, ensuring a balanced tone. These filters are indispensable tools in crafting a polished guitar sound.

Utilizing EQ in Guitar Amp Simulators

Guitar amp simulators often come with built-in EQ sections. Understanding how to utilize this EQ to shape your guitar tone is essential. Experiment with different settings to find the sweet spot that aligns with the desired amp tone, keeping in mind the broader mix context.

Contextual EQing: Carving Space in the Mix

It's vital to EQ your guitars within the context of the full mix, ensuring they carve out their own sonic space without clashing with other instruments. This often involves making strategic cuts to allow other instruments to breathe, achieving a harmonious and balanced mix.

Advanced Techniques: Mid/Side EQ

For a wider and more spacious guitar sound, consider using mid/side EQ techniques. This method allows you to EQ the middle and sides of the stereo field differently, creating a broader, more immersive sound stage that can enrich your mix substantially.

Automation for Dynamic EQ Changes

To add a dynamic element to your guitar tracks, consider using automation to change EQ settings over the course of a song. This approach can enhance the emotional trajectory of a piece, creating moments of intensity and relief through evolving tonal shifts.

The Art of A/B Testing

A/B testing, the process of frequently switching between the unprocessed and processed signal, is a valuable technique. It allows you to maintain perspective and ensure that your EQ choices are indeed improving the sound, fostering a disciplined approach to EQing.

Drawing Inspiration from Reference Tracks

Using reference tracks can be a guiding beacon in the sea of frequencies. They help in shaping the direction of your EQ choices, providing a benchmark to aspire to. Choose tracks that are well-produced and align with the tonal characteristics you desire in your mix.


Mastering the art of EQing guitars is a journey of fine-tuning, a pursuit of the perfect tone that can elevate your tracks from good to great. It’s a delicate balance between science and art, requiring a deep understanding of frequency ranges alongside a keen musical ear. Remember, there is no one-size-fits-all approach, and experimentation is your greatest ally. May this guide be a solid ground from which you explore the limitless sky of guitar tones, crafting soundscapes that resonate deeply with your audience.
