Where Does An Electric Guitar Get Its Power From?


When you pluck the strings, the movement of the wire strings generates electricity in the pickups’ magnetic field. Electricity is created when a wire moves within a magnetic field, therefore an electric guitar really creates electricity.

In this article, I’ll go through the different parts of an electric guitar in order to answer the question “where does an electric guitar get its power from?”

So without further ado, let’s get started!

The Different Parts of an Electric Guitar

When it comes to where an electric guitar gets its power from, let’s start with the most obvious part: the body of the guitar.

The body of a regular electric guitar is made out of wood in order to resonate with sound and produce the desired tone.

The type of wood used in an electric guitar affects not just how it sounds but also how it looks when being played.

Alder is one good example that people often use for electric guitars because it’s lightweight yet still produces great tones.

This makes them ideal for rock players that need to be able to move without having too much weight on their backs.

Some folks like basswood for its affordability while mahogany has become widely used in many types of instruments over the years of its ability to deliver classic tones.

There are of course other types of woods that you can use to build an electric guitar with but I’ll leave it on you to learn more about them if you like!

The Neck of the Electric Guitar

One important thing to remember is that the body isn’t where everything on an electric guitar is housed.

There’s actually another part on the instrument which connects the strings up to the power source.

This part is called the neck.

The neck houses all of your strings and has some extra bits within it in order for your fingers to press down upon them while plucking or picking.

How does this help us answer our question though?

Good question!

Well, since every string needs some sort of piece that can push down on it, there needs to be a place for that and the neck is where it happens.

Since we’re now aware of this fact, we can move on and learn about what’s inside the body of the electric guitar.

The Bridge of an Electric Guitar

Next up is another very important part of the instrument: its bridge.

The bridge is located on the lower bout of the body and serves as one end of the vibrating length of the strings, with the nut being at the other end of the fretboard.

You might have heard people talking about having a whole lot done with their guitars so they could go from one tuning to another faster by “tremolo” or “whammy” bars.

These are typically built into the bridge section of your guitar and they better allow you to do those things with your instrument because, without a place for them to sit, tremolo bars would be quite useless.

There are essentially two types of bridges you can find on an electric guitar: fixed bridges and floating ones.

Let’s take a quick look at the differences between them so you’ll know which one you’re dealing with if you ever need to fix it.

Floating bridge

A floating bridge has a wooden or metal arched base that is held in position solely by the strings’ downward pressure.

If the bridge is moved even slightly while re-stringing, the intonation will be incorrect (some Gretsch instruments have “pinned” bridges that eliminate this).

A floating bridge is attached to the top of the guitar by two or three screws.

The type of strings passing over it will affect its tuning stability.

The string saddles are usually adjustable for distance from the fretboard, and height above it, although these functions may be combined into one adjusting element.

Fixed bridge

Fixed bridges are screwed into the guitar’s body and rest on saddles, making them a type of hardtail.

Fixed bridges are a good choice for many players because they offer excellent tuning stability and tend to be appropriate for any type of stringing.

A fixed bridge can be harder to set up to get the right intonation but it won’t come undone when you need to re-string so it might appeal if you don’t want that extra step in your process.

Do electric guitars need to be plugged into electrical outlets?

Electric guitars have strings, just like acoustic guitars, and they vibrate and produce sound if you pluck or strum them.

The body and neck will resonate with the strings, amplifying the noise to some degree, but the only way to get the strings vibrating enough to produce a good sound is by using an amplifier.

If you were wondering if electric guitars need to be plugged into electrical outlets in order for them to function properly, then you should be happy with yourself because you’d be right!

Electric guitars absolutely need their amplifiers and it would be very difficult to play one without the other.

Remember that bit about the neck housing strings?

Well, it’s there for a reason and that is because they need something to transfer their vibrations into after you strum them.

The only way this can happen is if the amplifier makes those tiny electrical currents that create sound waves in the air.

There are ways for you to get sound out of your guitar without an amplifier but it would be very difficult and it typically requires special equipment so you’ll probably want to stick with the amplifier if at all possible.

How Does An Electric Guitar Work?

You got the technical side of things down pretty well there!

Now you can move on to some simple stuff like learning how an electric guitar works.

Electric guitars produce sounds by magnets and electricity coming together (you’ll find out more about those below).

There are some specific pieces of equipment inside your guitar that you need to know about, too.

The Pickups

These pick up the sound vibrations from the strings.

The neck pickup is used for the “rhythm” sound (the thick, lower sound) and it typically has a warmer tone, while the bridge pickup will be responsible for that bright “lead” or treble sound you hear when you play higher up on the fretboard.

These are great places to start if you want to start understanding electric guitars.

Now let’s take a quick look at the pickups on an electric guitar.

Various configurations have been used for this purpose, from dual “stacked” single-coils, to flush mounted single coils .

Typically these are not intended to provide a direct audio output (as with active electronics ) but instead a magnetic field to induce a current in the strings’ pickup coil.

Typically this current is then passed through a simple low-pass filter circuit to reduce unwanted higher frequencies, and then into an amplifier.

This configuration produces a distinctive tone with characteristics of lower feedback, increased sustain, and harmonic overtones.

The Treble Booster

This is used to boost the tone of your guitar.

It’s simple in that all it does is introduce an extra resistor into the circuit when you turn it on.

If you’re playing to a clean sound this will let more treble through, which creates a nice edge to your sound, but if you’re playing with distortion it can make things a bit too treble-y for your taste.

The Tone Controls

Lastly, you have tone controls that are used to change your sound as much as possible.

This is where all those knobs on your guitar come in.

These will also shape the tone of your sound and let you get that perfect level of volume and treble.

What energy do electric guitars use?

Electric guitars use electromagnetic energy to produce sound.

Electric guitars need their amplifiers in order to function properly.

Without them, it would be very difficult to play or listen to one.

When you pluck a string on your guitar, the vibration of that string causes the pickup coil inside your guitar to vibrate.

These vibrations are changed into electrical energy.

This is the magic of how your guitar works!


Q: How does an electric guitar pick up sound vibrations to convert into electrical energy?

A: The pickups located on the neck and bridge of the guitar accept sound vibrations from the strings, which are then converted into electrical energy.

Q: How do electric guitars work?

A: Electric guitars make sound by magnets and electricity coming together. This also explains why electric guitars need some type of power source to be able to work properly.

Q: What are the main components of an electric guitar that change electrical energy into sound?

A: The pickups, tone controls, and amplifiers interact with the sound energy to make it loud enough for you to hear.

Q: How do pickups work on an electric guitar?

A: Two types of pickups are most commonly used on an electric guitar – single coils and humbuckers. Each one uses a different type of magnet and interacts with the sound in a different way. The pickups pick up vibrations from the strings and change them into electrical energy.

Q: What does an electric guitar use for electrical energy?

A: Electric guitars need some type of power source, and that is where the amplifier comes in. The amplifier changes that electrical energy into sound which you can hear through your headphones or speakers.
