Guitar Kill Switch Guide: What is it and Do You Need One?

A Kill switch is one of those guitar terms you may have read about but not fully understand. They’re not all that common but can be an interesting addition to your playing.

I actually installed a kill switch in an old guitar of mine to test it out. It was a fun experiment and a pretty easy modification to start with if you’re new to that sort of thing.

It also gave me a clearer idea about kill switches and how they work. I got direct experience of using one and what they can do.

So let’s take a look at what a kill switch is, what it does, why you might want one and more.

What is a Guitar Kill Switch?

A guitar kill switch is a switch or button that you use to quickly cut off the sound from your guitar. When you press or flick the switch it ‘kills’ or mutes the guitar, essentially stopping the signal being passed to the amplifier.

The switch is usually found on the body of the guitar and can be a normal toggle switch or a button you press or hold down.

Kill switches are sometimes referred to as a “kill button” or “mute button”. Most guitars don’t come with a kill switch and so have to be modified to install one.

How Does it Work?

When the kill switch is activated it cuts off the signal between the pickups on the guitar and the amplifier. With no signal between the two then no sound is produced even when the strings are plucked or strum.

You can turn the kill switch on and off quickly, stopping and starting the signal between guitar and amplifier, which creates distinctive and unique types of sounds like stuttering and cupping effects.

This video gives a really good demonstration of using a kill switch button:

History of the Kill Switch

Kill switches have been around for along time. In the 1970’s Eddie Van Halen and Randy Rhoads began experimenting with kill switches and using them in certain songs. At first they achieved the technique by using their volume control.

But as that wasn’t very practical or reliable the kill switch we know today was invented.

Moving in to the 1980’s the kill switch became more popular, mostly in heavy metal and rock. Guitarists like Kirk Hammett of Metallica and Dimebag Darrell of Pantera used the kill switch at times that helped to define the sound of those bands.

Types of Kill Switches

There are a few different types of kill switches that you can install in your guitar.

  • Latching Kill Switch: A latching kill switch is a standardised switch that stays on until it is manually turned off. It’s often used for a more sustained effect such as a complete silence of the guitar.
  • Momentary Kill Switch: is engaged by pressing and holding down a button. When you hold the button down the signal between guitar and amp is cut off and the guitar is silenced. But the second the button is released the signal is reestablished and the sound returns. This allows the guitarist to create stuttering type effects and rhythmic interruptions.
  • Push-Pull Potentiometer Kill Switch: this type of kill switch isn’t a standalone switch but instead built into the volume knob or tone control. This can be preferable to the other types because it means you don’t need any extra hardware and it is easy to access by being part of the existing controls.

Do You Need One?

You definitely don’t need one. You may want one though.

Kill switches aren’t common and don’t get used all that much. But the effects they create are unique and so if you like really like what they can do then it might be worth considering modifying and installing one on your guitar.

If you’re a beginner or fairly new to the guitar then it’s probably best to focus on mastering the basics first. You can always play will kill switches later on when you’re more comfortable with the instrument.

Which Guitars Can Have Kill Switches?

Any guitar can have a kill switch. The only thing to consider is that it might be more difficult to install one on certain guitars.

Depending on the type of guitar it can be awkward to wire and drill the hole for the switch to go through. You ideally want a lot of room under the pickguard.

Famous Kill Switch Users

While they aren’t used very much some of the most famous guitarists have utilised the effects kill switches create.

  • Tom Morello
  • Eddie Van Halen
  • Buckethead
  • Jonny Greenwood
  • Matt Bellamy
  • Rob Zombie
  • Chris Broderick

Installing a Kill Switch

Installing a kill switch is one of the easier guitars mods you can do. I wouldn’t recommend it if you’re a total novice but it’s definitely worth attempting if you’ve played for a while and have an old guitar you don’t mind experiment on (and possibly ruining!).

How you install your kill switches will depend on the type of switch you opt for. And what guitar you’re installing it on will play a role in how you do it too.

The most common and probably easiest way is to drill a hole in the body of your guitar. You then run a wire from switch, placed inside the hole, to the pickups.

This is the most popular way because it can be done with minimal damage to the guitar. You just need to have the confidence to drill a hole through quite possibly your beloved guitar!

Alternatively you can install a push-pull potentiometer kill switch. This involves replacing one of the guitar’s existing volume or tone control knobs with a switch.

This is less invasive but a little more difficult to do, especially if you’re new to modifying guitars. However it doesn’t involve drilling any holes which is definitely a positive.

Getting a Luthier or Guitar Tech to do it

If you’re not confident about installing one yourself then it’s an easy job for a guitar tech or luthier. It’s relatively affordable too.

About Andy Fraser

I'm Andy and I've been crazy about music, and specifically the guitar, for longer than I can remember. It's this passion and enthusiasm about all things guitar that drove me to start this website. A place where I could talk about the gear, techniques and general awesomeness that is the best instrument. I began playing somewhat late compared to a lot of people. I was 15 years old as it had taken me a while to find the confidence to believe in myself and take that step to learn to play an instrument. It started my lifelong love of music and playing in general. Since then like so many before me I've become an addict and gone through more guitars, amps and gear than I care to remember. Guitar Inside Out is my way of sharing that love and passion with the music community and hopefully inspiring and helping others to enjoy it as much as I do.
