What is a compressor pedal?

The compression effect is not as audible as other types of effects such as reverb and distort. However, compression is crucial especially when you want to narrow down the dynamic range of your audio signal.

A compressor pedal is like an automatic volume control which reduces your audio signal whenever it exceeds a particular level. Either the pedal or your speaker and amplifier predetermine the said level.

Simply put, a compressor pedal quiets audio signal parts that are too loud. Then, it will also make quiet audio signal parts stronger. This whole process is what compression is all about. It is also how your compressor pedal narrows down the dynamic range of your audio signal.

What to Look for a Compressor Pedal?

what to look for a compressor pedal

Like any other effect pedals, a compressor pedal needs to have certain fundamentals and meet appropriate standards. For none beginner musicians, guitar effect pedal placement is critical. Which pedal effect comes first or last will significantly affect how your music is going to sound like.

For a lot of musicians, the usual order would be: compressor first, then drive pedal next. This is why you must be quite particular in choosing the best compressor pedal which works for you.​

This is also to ensure that your compressor pedal works as naturally as possible with your other effect pedals. After all, your compressor pedal SHOULD clean your audio as much as possible.​

If it does the opposite and makes buzzing sounds instead, then that would defeat its purpose, right?

The first you would usually look at a compressor pedal is its knobs and controls. This is critical because too much compression wouldn’t sound nice either. Some of the controls you’ll probably see in a compressor pedal would be: level, tone, attack and sustain.​

  • Level - The level knob adjusts how much the pedal’s compression effect would be in your music.
  • Tone - The tone knob is what “cleans” the audio quality of your music.
  • Attack - The attack knob controls when and how fast the compression takes into effect.
  • Sustain - The sustain knob, of course, supports a note. This knob controls how long an individual note should last.​

For beginners and musicians on the go, another factor you should look into is the pedal’s simplicity. It is also crucial that you know how your compressor pedal works and that you work smoothly with it.

Even though you might’ve read a whole page about how compression works already, the whole process might still seem complicated especially to beginners. This is why you must not only look at how many knobs there are in your pedal. You must also consider how these buttons work and how you can best utilize them.​

Lastly, know you want so you know what to look for. Most people have trouble finding the best compressor pedals for them because they are looking for the wrong kind. There are compressor pedals which only work with a bass or an electric guitar. And you need to keep this mind.​

Some compressor pedals which only for work with electric guitars can kill some notes for the bass guitar. This is why at the end of the day, your preferences and needs should come in first.​
