Choosing the best bass compressor pedal

Benefits of using a bass compressor

Bass compressors are used to reduce the “Dynamic Range” – the difference between the loudest and lowest parts of the bass sound. In other terms, lowering the loudest parts of the signal it is processing and boosting the softest. The results? A fuller, smoother, and more professional bass sound. Knowing how to use a bass compressor will make your bass sound more professional.

On the other hand, using a bass compressor the wrong way will over-compress the sound and squeeze the life out of it. 

Adding a bass compressor to your toolbox of effect pedals is beneficial in multiple ways:

  • Playing live: When you are out gigging and doing live performances it’s more likely that you’ll encounter poor in-house equipment. Using a bass compressor helps you control your sound peaks and prevent audio clipping and unwanted distortion.
  • Smoother sound: It really goes without saying but you don’t want your volume all over the place. A bass compressor pedal will give you a more professional bass sound that is consistent but still cut through the mix. This will be beneficial for both live shows and recording sessions in the studio.
  • Balance out slap bass style playing: There is a huge difference between normal finger-style playing and slap-style playing. A bass compressor will balance the dynamic range and keep the volume in line. 

Where in the signal chain should you put a compression pedal?

Some bass players put their compression pedal first while others have it as the last step in their signal chain. I usually put the bass compressor pedal at the beginning of my signal chain. Doing so sets up a more consistent signal for the rest of my pedals. Like every other device in your signal chain, bass compressor pedals raises the noise floor. If you put the bass compressor at the end, it could amplify the unwanted noise.

You could argue that putting it at the end of the signal chain will add some smooth compression to your other effects as well. The key is to try any combination you can think of and use it where it sounds the best for the kind of music you play. What other pedals you have in your chain also plays an important role.

What to look for in a bass compressor pedal

There are many great compressors available. However, the best bass compressor pedal will give you a fuller and smoother sound without amplifying the noise floor. Cheaper pedals will have fewer parameters, which means limited options. The most important parameters that influence the way a compressor operates are:


The threshold is the level that the signal needs to rise above for the compressor to kick in. When your bass signal is louder than the threshold, the sound will be compressed. If you set a higher threshold, only the loudest notes will be compressed. If the threshold is low, more compression will be applied to the signal.


The ratio determines how much compression will be applied when the signal is louder than the threshold. Most bass players choose a ratio ranging from 2:1 to 4:1, meaning that the signal will be attenuated by 2dB to 4dB every 1dB above the set threshold. This is a great start since you benefit from some peak reduction while still maintaining the dynamic range.  


The attack setting is essentially the reaction time of the compressor – determining how quickly the compression will kick in when the signal reached the set threshold. This will give you a more punchy bass sound. Dialing in a slow attack will allow the transients to pass without being affected by the compressor. Fast attacks will immediately compress the signal above the threshold. This can be used to tighten up performances or give you a more processed sound.

Release time

The release setting controls how long time it takes for the sound to go from the compressed state back to the original non-compressed state. Release time is usually much longer than attack time and can range from 60 ms to 2-5 seconds. Fast release (50-100 ms) is great for increasing the perceived loudness of the track while slow release is beneficial for smoothing out dynamic performances. The key is to experiment with the release setting. If it’s too slow, the compressor will make the sound dull and flat. A fast release can cause unwanted pumping sound, also known as the “breathing” effect.

Output level/make-up gain

Whenever you compress a sound, it lowers the output and you end up with a quieter signal than the original. This is where “output gain” or “make-up gain” comes into play. The make-up gain doesn’t affect the sound more than increasing the output. Adjust the make-up gain so you makeup for the amount of level that you have lost during compression.

Setting up your bass compressor

Dialing in the perfect setting on your bass compressor pedal can be tricky and sometimes it can be hard to hear the effect it has on your sound. The more you experiment and try different things, the better the result. These settings should only act as a starting point:

  1. Set your ratio to somewhere between 2:1 and 4:1
  2. Set your attack to somewhere between 75ms-150ms
  3. Set the release to 25ms-50ms
  4. While playing, turn up the threshold slowly until you hear a slight decrease in volume
  5. Start decreasing the attack time until the bass sounds less aggressive
  6. Tweak your output level until there is no difference in volume between the compressor being on and off

These steps will only set you on the right path. Use your ears – if it sounds good, it is good!

Wrap up

Dunlop M87 MXR is the best bass compressor available. It offers a great studio-quality sound and all the control options you will ever need. Many other compressors add a lot of hiss to your sound but the M87 is almost silent. With the 20:1 ratio setting, the M87 can also be used as a limiter, enabling you to soft limit your output volume.

It’s worth mentioning that every bass compressor pedal featured in this list will be a great addition to your existing setup.
