You might think that rocking out on an effects pedal is strictly an activity for lead guitarists, but bass solos are opportunities for you to shine, right?
There are plenty of pedals on the market for bass players to have fun and experiment with, a popular offering being the distorter.
What is bass distortion, you might be asking?
Defined simply, it involves inputting a source signal into an audio circuit and increasing the gain.
This is done until the circuit can no longer replicate the signal being received, resulting in a clipped waveform and saturated sounds.

Best Bass Distortion Pedals Buying Guide
Alright, you’ve had a look at the pedals we’ve laid out for you, but you’re still not sure which one makes for the best distortion.
Not to worry - here are the key features to look out for and the mistakes you should try not to make when shopping.
Messing around on your bass might not feel particularly scientific, but there are a few key words you’re going to want to understand before you begin.
For example: tone, gain and sustain
A bass guitar’s tone or timbre is the quality or character of a musical sound, not to be mistaken with its pitch (from low to high) or intensity (how deep the sound is).
For example, adjectives to describe tone might include smooth, rough, smoky, flat and heavy.
Sometimes falsely understood as referring to volume, the gain setting determines how hard the pre-amp section of your amplifier is working.
Adjusting this will also impact on the amount of distortion you experience altogether.
In layman’s terms, gain is how ‘clean’ or ‘dirty’ your sound comes through, regardless of the master volume’s level.
You can have a quiet dirty sound, or a loud clean sound, and each is controlled with the handy gain knob.
As the name suggests, a bass guitar’s level of sustain essentially means the level of endurance of a string’s vibration.
The higher your sustain is, the more time your string vibrates for, and the longer a note will hold without dying out.
Overdrive, fuzz and distortion: what’s the difference?
As we’ve covered, distortion involves altering a sound’s wavelength before the note is even heard, through ‘clipping’.
It is also used interchangeably with the terms fuzz and overdrive as other ways to change how a bass sounds.
What are they?
An overdrive pedal is designed to boost your amplifier’s existing valves into distorting more, as the name might suggest.
It’s a simple standalone effect that increases your midrange and provides some grit to the bass sound produced.
It is most effective when dialed into a sterile bass tone, helping bring life to a particularly boring sound.
Make sure you start with a lighter touch to begin with and build up as you go. Otherwise you’ll end up with a messy, chaotic sound.
Aiming for a harsher saturation of sound, you’re creating a sound antithetical to the softer, more harmonic clipping that occurs from distortion and overdrive.
This helps to mimic the more old-school synth sounds as well as limiting transients - which are simply non-repeating waveforms - that sound harsh on the ear.
Here’s a video to give you a better idea.
Why bother with a pedal?
What can you gain from a distortion pedal that a regular bass sound won’t provide?
For a start, they open up a whole world of lower frequencies with which to distort your sound, far from the brighter tones you might be used to.
Likewise, a distortion pedal will increase your sustain level, meaning that the notes you play will vibrate for longer.
They will also sound crisper, bringing a level of continuity to your music.
Should you play in a band and wish to shake things up with your next bass solo, a distortion pedal can be a great way to introduce some new sounds.
An ability to add wild and crazy twists to your rocking out might help in impressing your audience, if you have one.
An important factor to consider when picking up a distortion pedal is the amount of headroom it is capable of.
Basically, this means how high or how low the pedal can clip your signal, and thus how ‘dirty’ your sound will be.
Usually measured in dB (decibels) or kHz (kilohertz) by manufacturers, the higher your headroom, the more range you’ll have.
Range here refers to how far the sound can be distorted and whether it will be jarring to the ear.
Size and style
Distortion pedals are available in a variety of shapes and sizes, but their aesthetic qualities usually serve no purpose in terms of how the pedal functions.
Regarding size, your only question should be whether it will fit in your current pedalboard setup or not.
The more knobs and buttons and settings a distortion pedal offers, the more experimentation you’ll be able to perform and the greater range of sound.
If playing around is your cup of tea, pick a pedal with plenty of options.
Frequently Asked Questions
What does audio distortion sound like?
As explained earlier in the article, distortion, overdrive, and fuzz are forms of audio signal processing that serve to impact the sound of your bass.
By increasing the gain, you can produce a ‘gritty’, ‘dirty’, ‘fuzzy’ or ‘growling’ tone.
Also described as ‘warm’, the clipped signals, pushed past their maximums, are boosted with sustain.
This creates a compressed sound with harmonic and inharmonic overtones, depending on the type and intensity of distortion used.
How do you get crunchy distortion?
‘Crunchy’ distortion is just another way of saying that a lot of distortion is occurring, as determined by the amount of gain and distortion you have while playing.
Increase your gain and turn up that distortion for maximum crunch!
How do you get a good distorted bass tone?
At its most basic, a distorted bass tone is best achieved by running two signals at once: a clean one and a dirty one.
If those lower frequencies are distorted too much, the sound will lose its crispness and you’ll struggle for precision with your notes.
Splitting your signal into two chains with a splitter (or two amps if you’re desperate) and using each for a different purpose, works best.
You combine clean low frequencies and higher, bassier notes, without losing sound quality.
If you only have the capability for distorting one signal, using a distortion pedal built specifically for use with a bass guitar is better.
Using pedals made for a bass in particular increases the likelihood of hitting that low, rumbling sweet spot.
Similarly, a bass amplifier works better than one built for general use, as they’ll keep the sound clean and simple.
Some even have built-in distortion features, which will save you from needing to pick up a pedal if you don’t have the spare cash.
Why does my distortion pedal sound bad?
There are a couple of reasons your distortion pedal might be failing to create the sound you’re looking for.
You could even be producing an entirely new and horrible sound you never wanted.
An easy fix is to check your cable connections - is everything plugged in tightly and into the correct sockets?
Is there any visible fraying or damage to the wires?
Try switching out the set you’re using for some fresh ones and see if that helps.
Your amp could be the problem, not necessarily your distortion pedal.
If your amplifier is cheap, poor quality or doesn’t produce a nice sound on it’s own, you’ll struggle to achieve that dirty distortion you’re looking for.
It may also be that your amp has an in built noise gate, a feature manufacturers include to actually prevent sound distortion.
With a gate in place to prevent any alterations to the sound’s signal, you’ll be robbed of precious tone.
If your volume is kept to a minimum to prevent angry neighbors or avoid feedback, it could be making your sound ‘thinner’.
We recommend increasing your volume and turning down your gain, adjusting while you play based on the sound.
