Whether you have been browsing various gear forums, checking out your favorite guitarists’ pedalboards, or scrolling through the @PedalHaven Instagram account – chances are you have seen a lot of different compressor pedals.
However, if you’re new to the guitar pedal world, or just aren’t quite sure if a compressor pedal is right for you – then this guide will help you wrap your head around what exactly a compressor pedal can do for you.
What Does a Compressor Pedal Do?
Have you ever found yourself asking, “What do compressor pedals do?“
Chances are, you’re not alone.
The main function of a compressor pedal is to intensify (or beef up) an instrument’s sound. Compressor pedals do exactly what it sounds like, compress your signal. They do this by reducing loud sounds and amplifying quieter sounds, which makes a much more consistent sound from note to note, and also allows notes to sustain for much longer.
This is especially popular for guitarists (and bassists!) who typically play with a clean tone because notes played on a “clean” guitar can lack sustain – meaning the sound dies out rather quickly. Compressing this sound will allow the notes to extend much longer without the need for distortion or overdrive.
To give you an idea, here’s our demo of the iconic Compressor+ from Keeley Electronics:

Do You Need a Compressor Pedal?
The truth is: it depends. If you’re playing the blues, probably yes. However, if you’ve never tried one, we’d suggest giving it a chance. Perhaps pick up a cheap compressor pedal, like a Donner Ultimate Comp, and see how you feel. It may be exactly what you’ve been missing. If you find yourself playing with a “clean” tone, or use an electric acoustic guitar, then a compressor pedal is always a great tool to have in your arsenal to help liven up your sound.
How Important is a Compressor Pedal?
A compressor pedal can be incredibly important for achieving the guitar tones you want. Many people seem to overlook how vital a compressor pedal is because the changes they make to your tone aren’t as drastic as something like a distortion or overdrive pedal, but investing in a good compressor pedal for your pedalboard can be an absolute game-changer when it comes to your sound.
Compressor pedals are hugely important if you are a guitarist that utilizes any of these techniques:
- Finger Picking
- Hammer-Ons and Pull-Offs
- Harmonics
Compressor Pedal Settings
Okay, so you got a compressor pedal – Now what?
Much like any guitar pedal, a compressor is no different. By that, we mean different settings will help you accomplish different goals. If you’re a blues guitar player, you may prefer wildly different settings than a country music player. And of course, everybody has different gear, playing styles, and preferences.
When it comes to setting your compressor pedal, the best thing to do is dial all of the knobs to “noon” (pointing straight up) – and then tweak the various settings to your liking.
I personally like setting a compressor with a rather low amount of compression and leaving it on at all times. Setting a compressor pedal like this makes it seem like it’s not really there, but if you listen closely, it is doing its job!
How to Use a Compressor Pedal
As we mentioned above, a compressor pedal is used to help add some bulk to your guitar’s overall sound. Many guitarists turn on their compressor pedal at the beginning of their set and never turn it off until they are done playing. However, if you have a certain part in a song that could benefit from more sustain, perhaps a wild solo or a pretty finger-picked part, you may only need to turn it on for that moment.
It is best to bring your compressor to your band’s practice and test out playing different riffs with or without the compressor. This will allow you to pick out parts where the pedal really benefits your overall sound.
Where Should A Compressor Pedal Go on your Pedalboard?
A compressor pedal usually goes at the front of your signal chain. But You should always think about and experiment with how you order your pedals on your pedalboard. Much like any effect, a compressor pedal will offer different tonal options depending on where it is in your signal chain. Most of the time, it is best to put your compressor first. That way it sends a clear, consistent sound through the rest of your effect pedals.
Try it at the beginning of your signal chain, and then move it around to see what sounds best to you.
Here are a few frequently asked questions on where a compressor pedal should go.
Compressor Before or After Overdrive?
A compressor typically is placed before any overdrive effects in your pedal chain. Of course, this is open to experimentation, because some overdrive and compressor pedals will react differently to one another. Give both options a try!
EQ Before or After Compressor?
Typically you will want to place your EQ pedals before any compressor pedals. This will usually lead to a more warm, rich tone. It really depends on the sound you are looking to achieve, so definitely try out different combinations.
Compressor Before or After Wah?
In this situation, the wah pedals are almost always first. Having a compressor after a wah pedal helps bring out the “vocal” qualities of a wah pedal.
Can You Use a Compressor with Distortion?
Yes. You can absolutely use a compressor pedal with distortion. This can really help bring your lead guitar tones and solos to life. However, since distortion is also technically a type of compression, it is important to set both pedals so they interact well with one another and don’t over-compress your signal.
