Best Bass Distortion Pedal

Best Bass Distortion Pedal for Metal Bands

Distortion is an effect that lives at the heart of modern Rock and Metal Music. You can find this effect in many other genres as well, from dubstep to grunge. You can also give it to electric guitars.

However, distortion is something for almost any instrument. The second most popular way to use it is with a bass guitar. 

Applying distortion to your bass helps to make the signal much louder and dirtier. This is great for adding a bit of dissonance to your signal, which helps to create the punchy sound used in punk and rock.

You could buy a standalone distortion unit for plugging your instrument into, but this is expensive, and will take up a lot of space. 

By far the easiest way to add this effect to your music is through a pedal. You can use pedals with both guitars and basses to alter the signal from these instruments in several weird and wonderful ways.

In this article, we have gathered together some of the best bass distortion pedals that you can buy online.

Bass Distortion Pedal Buyers Guide

You might think that manufacturers build all bass pedals the same. However, there is actually a lot of variety between the different models.

Finding the right one for you will largely come down to the style of music you want to play. In this section, we will offer some helpful tips for finding the right bass distortion pedal for you. 

What genre is best for a distortion pedal?

Certain pedals will work better for playing different styles of music. If you just want a generic pedal that will work for ‘Rock and Roll’ or ‘Pop’, then you should look for a pedal that has a warm sound.

Warm distortion has a more gentle, fuzzy feel that isn’t as heavy as the dissonance offered by pedals made for heavy metal or punk. 

If you are buying your first distortion pedal, you want to get a warm model. This allows you to get a feel for the unique sounds this effect can create.

Afterwards, if you decide you want something different from you can always buy a new pedal that matches the sound you want. 

What are good controls for a bass distortion pedal?

Most pedals will come with at least three basic controls. These include level, drive and tone. Level is often the control that adjusts your output volume, while drive dictates how much distortion applies to your clean signal.

Tone is often used to control the type of distortion, making it either warmer or more dirty. 

These are the only three controls that you need for a good distortion pedal. However, there are other features that can be very useful as well.

Switches for applying a bass boost to the output signal are especially useful if you want your bass to be extra punchy. 

Equalizer controls are also a strong feature that will allow you to shape your sound. EQ knobs let you cut or boost certain frequencies, often those in the high and low ranges.

Another useful control is balance, which lets you blend your dry and wet signals. This is another feature that gives you more control over your tone to get your sound just the way you want it.

These extra controls are useful, but aren’t essential and may just make the pedal less accessible for complete beginners.

You only want to look for a pedal with these features if you know you are going to use them, or will learn how they work. 

What does a switch do in a bass distortion pedal?

The switch is the main button on a pedal that you press to activate the effect. They come in two forms: pedal switches which are large, flat and button switches which are a single metal button.

The advantages of pedals is that you can press them down halfway. However, this feature isn’t too important in distortion.

That said, pedal switches are also much easier to tap with your foot without looking, so you can apply your effect without worrying about missing the switch. 

Button switches, on the other hand, can be more durable, but are a little hard to hit. Since buttons are so much smaller than pedals, they allow the pedal box itself to be much more compact.

This means buttons are a brilliant choice if you have a pedal board that doesn’t have the space for a larger model. 

What is the best size for a distortion pedal? 

Many musicians will have multiple effects pedals arranged onto a board. This keeps all of their effects in one place where you can access them during a gig or practice session. 

If you have a pedal board yourself, then you will want to buy a pedal that can fit on it. This won’t be a problem if your board is relatively empty, but will be trickier if you already have a lot of pedals.

In this case you will need to decide which pedals you want to kick off the board or look for a very compact model like the Keeley Super Fat we looked at earlier. 

Frequently Asked Questions

How Do Distortion Pedals Work? 

Distortion pedal raises the gain of an input signal above its peak. This means that the peaks and troughs of the signal are cut by a phenomenon known as clipping.

When clipping occurs, it creates harmonic overtones and dissonance to make the signal sound muddy and unclear. This process also produces a natural sustain, which is why notes played through a distortion effect will go on for much longer. 

What Is ‘True Bypass’?

You will see many pedals described as having ‘True Bypass’ on their switches. This simply means that the clean signal can pass straight through the pedal without being altered in any way when the effect is not active.

Pedals that don’t have this feature may subtly affect the sound of your clean signal, even when turned off.
