Introduction:
Electric guitars, unlike acoustic ones, need amplifiers to produce sound. This is because the pickups on electric guitars are electromagnetic transducers that convert the strings’ vibrations into electrical signals, which are then amplified by the amplifier. However, this also means that electric guitars are more susceptible to distortion and feedback than their acoustic counterparts. In this blog post, we will explore what makes electric guitars scream and how distortion affects their sound. We will also discuss the difference between single coil and humbucker pickups and how they contribute to the guitar’s tone.
What Makes Electric Guitars Scream?
Guitarists often strive for a tone that is “screaming,” “raunchy,” or “dirty.” This is achieved through distortion, which is the intentional clipping of the guitar’s signal to produce a distorted sound. Distortion can be created in various ways, including overdriving the amplifier, using pedals, or even just turning up the volume on the guitar.
Distortion is a desirable sound because it adds complexity and richness to the guitar’s tone. It makes the guitar sound fatter, louder, and more assertive. However, too much distortion can make the sound harsh, unpleasant, and unusable. Finding the right amount of distortion is a delicate balance that depends on the guitar’s pickups, amplifier, and the player’s playing style.
Distortion also affects the guitar’s sustain, which is the length of time a note can be held before it fades away. Distortion can increase the sustain of a note by compressing the signal and preventing it from decaying quickly. This gives the guitar a more pronounced, singing quality, which is especially useful for solos.
Can Distortion Produce Cleaner Sound?
Interestingly, distortion can also be used to produce a cleaner sound. This might seem counterintuitive, but it is because distortion clips the guitar’s waveform, removing the high-frequency content. This leaves behind a more midrange-heavy sound, which can help a guitar cut through a mix better.
For example, a guitarist playing in a band with another guitar player and a bassist might find that their guitar’s tone is getting lost in the mix. By adding a moderate amount of distortion, the guitar’s midrange frequencies can be boosted, making it sound more distinct and easier to hear. This can also be useful for rhythm guitar parts that require clarity.
What’s the Difference Between Single Coil and Humbucker Pickups?
One of the most significant factors in shaping the electric guitar’s sound is the pickups it uses. Pickups are magnets wrapped in coils of wire that are placed under the guitar’s strings. When the strings vibrate, they produce a magnetic field that is picked up by the pickups and transformed into an electrical signal.
There are two main types of pickups: single coil and humbucker. Single coil pickups are made up of a single coil of wire, while humbucker pickups have two coils arranged in a way that cancels out the hum and noise that single coils are prone to.
Single Coil Pickups:
Single coil pickups are known for their bright, punchy tone. They produce a clear, articulate sound that is often associated with funk, country, and classic rock. However, because they only have one coil, they are more susceptible to noise and interference, especially when played at high volumes.
One of the most famous single coil pickups is the Fender Stratocaster’s. It has a signature sound that is crisp, bright, and twangy, making it perfect for clean, melodic playing. However, when pushed into distortion, it can produce a biting, cutting tone that is perfect for blues and rock.
Humbucker Pickups:
Humbucker pickups were invented in the 1950s to address the noise and hum issues that plagued single coil pickups. They work by having two coils wired in series but with reverse-wound and reverse-polarity configuration that cancels out the sound waves from outside the guitar. Additionally, the two coils increase output pickup, making humbucker pickups sound louder than single coils and covering a wider range of frequency.
Humbucker pickups are known for their full, warm sound that is characterized by a thicker low end, smoother highs, and less twang. They excel at distorted sounds and are often associated with classic heavy metal or hard rock. Additionally, the construction of the humbucker adds a thickness to the sound, making it very popular in jazz, blues, and fusion genres as well.
The most notable example of humbucker pickups is Gibson’s PAF (patent applied for) pickups, which were the first widely used humbuckers. They are known for their versatility, richness, and ability to produce a wide range of tonalities.
Conclusion:
In summary, electric guitars scream when they are distorted, which adds complexity and richness to the guitar’s tone. Distortion can also be used to produce a cleaner sound by boosting midrange frequencies. Additionally, the pickups used on electric guitars play a significant role in determining the guitar’s tone. Single coil pickups offer bright, punchy sounds while humbucker pickups provide full, warm sound with less noise. Understanding the different elements that influence the guitar’s tone can help guitarists select the right gear for their playing style and achieve the sound they are looking for.
