Why use a compressor pedal

When you do not use a compressor pedal you can notice that your notes are abrupt and, sometimes, they can get lost in the mix of the band's sounds.

Another recurring problem is that some notes are always higher than others depending on the string you play, that has to do with physics, which is a bit boring, but in summary is due to the width of the string.

Correcting those variations or the Attack of the notes is only possible with a compressor pedal.

The main function of a compressor pedal is to make each note have the same volume, solving the issue of mismatches due to leveling austerity or the problem of the strings. After all the sound will be much more natural and pleasant, and the noise and kick will be cleaner if you use a chain of effects.

What to look for in a compressor pedal

Each pedal on this list offer different solutions depending on the genre and musical style you are looking to reach, so the first thing you need to do is to define your music well.

Once you have established that, you can dedicate yourself to finding the right pedal, but keep in mind the next recommendations so that you nail the best bass compressor pedal.

A good compressor pedal should give you at least two fundamental adjustments for compression.

The first one is the Compressor, the one that will allow you to adjust your sound allowing you to achieve the softness or harmony you need.

The second is Level's; that will allow you to level the rest of the sound of your touch so that no note goes unnoticed.

Regarding the issue of whether you will use analog or digital pedals

You should always take into consideration that most analog pedals can generate noise, distortion or unwanted ghost notes, in addition to being difficult to set up.

On the other hand, the digital pedals avoid these problems in their majority by integrated switches which allow you to modify the sound; they also have LEDs that are practical visual aids, the major drawback is that many models have a problem with battery consumption.

Another fundamental aspect is the construction

Look for one of resistant design, which is able to properly support the footsteps, because sometimes you step carefully, and others you will do it with impetus.

Some things you should know about compressors

One the popular effects is the Sustain, it’s main purpose is to keep a note sustained for a longer period of time.

This effect lengthens the note as much as possible, with the compressor, the low sounds are leveled with the high ones; the result is that the time of fall of these notes is extended in comparison to when you do not use a compressor, so the Sustain is considerably longer.

Many types of equipment (Bass guitars included) are limited by the pikes in the signal, failing to function properly and ruining the sound when detail is most needed.

The compressor pedals for bass, by correcting such peaks, get the best out of your instrument and protect it from too high peaks.

Pro Tip ... when you achieve the desired sound, you can mark the setting with a delete-able marker so you always know in what position you need the knobs to be.

If you are a bassist who prefers to use slapping, there are those situations that you’ve probably noticed that the peaks are too high and your music is lost, in which case it will be very beneficial to use a compressor pedal in your presentations.

This way, reducing the natural dynamics of your bass will give you a more pleasant and professional sound.

On the other hand, it is advisable to start with a compression ratio between “2:1” and “4:1” and try a setting that suits your style within that range which is where the compression is more stable.


Definitely, the usage of compressor pedals is the best way to combat the downsides of your bass’s natural dynamics.

After we reviewed bunch of models, here are the distinguished ones. If you are looking for affordable prices, then you can go for the Kokko, compressor (FCP2), the Xvive Bass Pedal or the BEHRINGER Compressor / Sustainer CS400; each one is very effective considering the cost, especially the BEHRINGER.

If you have been using pedals for a while and expect results similar to those you get in studio, then you should get the Boss CS-3 or the Seymour Duncan Studio Compressor Pedal. They are models with excellent performance and construction.

In order to access as many settings from a pedalboard and obtain professional results in the process you will need the MXR M87, a pedal with 5 adjustment knobs and a LED indicator that lets you know exactly how much compression you achieve in your notes.

Keep in mind that any option you choose can present distortion or noise if you do not install it properly.

In addition, you will need patience and a good ear to reach the sound you are looking for.
