If you're looking to tame the low end of your bass tone, add some punch and even out those playing dynamics, you'll need one of the best bass compressor pedals. One of the must-have pedals on any bassist's 'board, a good bass comp won't make your sound completely different, but will instead help you deliver a more consistent performance.
Compression is one of the most misunderstood topics in all of music, so to put it simply, compression evens out the dynamics of your playing. It makes the loud bits quieter and the quiet bits louder. This is a very simplified idea of what compression is, because a great bass compressor does so much more than just that.
A compressor isn't the most flashy pedal, but it will improve your overall sound. It'll stop you sticking out in a mix when playing with a band, and help you add consistency and coherence to your playing. Many bass players swear by using compressor pedals, and you should too.
We've picked out some of the very best bass compressors available right now, whether you're new to the instrument or you want something with more options than you'll know what to do with. We've also got a handy FAQ section which answers loads of common questions if you want to know more. Let's get to it...

Origin Effects are known for making some of the best effects pedals out there, and this bass compressor is up there with the best of them. This is a studio-grade FET compressor with fully variable input, output and ratio controls so you can dial in exactly the level of compression you want, as well as how it reacts with your volume. There’s also a dry knob that allows for parallel compression – this means you can blend in your clean, unaffected signal alongside your compressed sound for a more natural tone.
Electro-Harmonix are one of the biggest names in the pedal game, so it’s only right that they have a unit dedicated to bass compression. The Bass Preacher is a compact pedal with two easy to dial in knobs and a three-way attack switch. Having the different attack speed settings allows you to control how quickly it grabs your signal and affects it.
On board the Hyper Luminal Compressor you’ve got four traditional-style knobs for controlling the amount of compression, attack and release time, output volume and a blend for your dry signal. Then you’ve touch sensors that control the compression ratio and the mode. It’s the ability to change the compression mode that really makes this model stand out, as you can choose between BUS (modeled after an SSL bus compressor), FET (1176 style), and SYM (Darkglass’s old Super Symmetry compressor pedal).

This pedal aims to replicate how a studio-style 1176 compressor would affect your bass signal, with some added clarity on that precious low end. It’s incredibly musical and very versatile, plus it’s built like a tank, so it’s impressively road-worthy.

In addition, you’ve got a high pass filter that leaves your low end untouched, while compressing the top end. This helps keep those bottom strings sound nice and fat, whilst keeping everything else higher up more in check. Lastly, there’s a single attack and release knob which allows for easy sweeping through various settings for how quickly the compression kicks in and finishes. This is a superb bass compressor, adding more body and sensitivity to your tone, whilst retaining your natural dynamics and expression.

Tone hounds might want a little more
Electro-Harmonix are one of the biggest names in the pedal game, so it’s only right that they have a unit dedicated to bass compression. The Bass Preacher is a compact pedal with two easy to dial in knobs and a three-way attack switch.
Having the different attack speed settings allows you to control how quickly it grabs your signal and affects it. So, whether you’re playing slap bass and want a quick attack, or playing with a plectrum and want some of that pick noise to come through first with a slower attack, then you’ve got all basses covered (pun intended).
This won’t take up much space on your pedalboard, and it does the job. It’s nothing fancy, but if you’re after something simple and easy to use with a range of applications then this is certainly one of the best bass compressor pedals out there.

Touch controls not for everyone
Featuring a blend of analog and digital technology, the Darkglass Hyper Luminal Compressor is functional, versatile and comprehensive, and affects your bass signal in a way that’s musical and dynamic, making it one of the best bass compressor pedals out there right now.
On board the Hyper Luminal Compressor you’ve got four traditional-style knobs for controlling the amount of compression, attack and release time, output volume and a blend for your dry signal. Then you’ve touch sensors that control the compression ratio and the mode. It’s the ability to change the compression mode that really makes this model stand out, as you can choose between BUS (modelled after an SSL bus compressor), FET (1176 style) and SYM (Darkglass’s old Super Symmetry compressor pedal).
Even if you don’t understand the differences between these various compression styles (and it really isn’t crucial that you do), it’s nice to have slightly different flavors of compression available at the touch of a button.

4. Empress Effects Bass Compressor
An full-featured bass compressor that delivers transparent tone
If you're looking for a bass compressor that won't color your tone and gives you plenty of options for tweaking, the Empress Effects Bass Compressor is hard to beat. This fully featured unit gives you lots of options but stays out of the way in terms of tone.
We love the metering on this pedal, with 10 LEDs that show you both gain reduction and input gain levels. There are plenty of controls for sculpting your sound too, whether you want something subtle or you want to make things really squishy. The ratios might be a little selective for some, but for most players, there are plenty of options here.
The sound of the Empress Bass Compressor is simply sumptuous. It'll make your low-end super fat and chewy with the right settings, and it always remains super transparent, keeping your original tone intact. There is an option to add some coloration via the switchable circuit, although it does add an EQ bump too.

5. MXR M282 Dyna Comp Bass Compressor
Control your low end dynamics with this compact compressor pedal
The Dyna Comp is somewhat of a legend within the world of compressor pedals, and the bass version lives up to that legend. Super compact, with a range of controllable parameters that make it easy to dial in your desired sound, the MXR M282 has it all, making it one of the best bass compressor pedals on the market.
This compressor is built around a CA3080 circuit that is known for having a good dynamic range and being transparent, meaning your inherent tone shines through.
What we really like about this compressor is the clean knob which lets you blend in your dry, unaffected signal as much or as little as you want. With this, you can get a nice, heavily compressed sound, then dial in some dry signal so that it doesn’t sound too squashed. The attack switch lets you choose between a slower, more vintage style attack and a quick, modern attack, making it ideal for pretty much any style of bass player.

Not versatile enough for some
This one-knob bass compressor manages to apply studio-grade, multi-band compression to your bass signal, whilst acting as one of the easiest to use pedals out there. If you want something that’s super simple to set up, without having to really get into the ins and outs of compression, then this could be the best option for you.
Whether you want a little or a lot, the TC Spectra Comp applies compression equally to your low, mid and high frequencies so your tone is balanced, punchy and sustains when you need it to.
As with many of TC’s pedals, the Spectra Comp is equipped with Tone Print technology allowing you to dial up some pretty big artists’ carefully tweaked signature settings with your smartphone, meaning that there’s actually quite a bit more packed into this tiny pedal than you might think.

Sounds very plain
Aguilar make some incredible bass gear including pickups, amps and bass effects pedals. The ‘TLC’ in their TLC compressor stands for trans linear control which is an analog dynamic circuit design. There’s a peak limiter on board so you don’t get those nasty volume spikes if you slap or pick a little too hard.
The four knobs allow for quite a lot of control over the compression. The 'slope' knob is essentially a ratio control that determines the amount of compression, 'threshold' controls at what level the compression kicks in, 'attack' is how quickly it kicks in and 'level' helps compensate for gain loss so that your volume is where you need it to be.
This is all housed in a really sturdy and incredibly road-worthy casing that will stand the test of time. It compresses in a musical way and really allows you to shape your bass tone how you want it.

Not much
This compact pedal offers bassists pro-level, multi-band compression that responds well to dynamics and allows your tone to remain clear. There’s also a handy display on board so that you can see easily when your signal is being compressed, and by how much.
The four knob layout is easy to dial in, but gives you a good amount of control over various parameters of the effect. You’ve got knobs for release (i.e. when the compression stops), overall level, the ratio of compression and the threshold at which compression kicks in. Because it applies compression differently to different frequency bands, the low end of the bass remains dynamic and tight, whilst enhancing the mids and high frequencies.
We’d expect nothing less from Boss, what with them being possibly the biggest manufacturer of effects pedals in the world, and this model does exactly what it needs to, at a fair price.

Not specifically a bass pedal
Whilst this isn’t specifically a bass compressor, the wonderfully titled Kongpressor is really versatile whilst remaining easy to use. There’s also a handy metal bar on the pedal so you don’t accidentally knock the controls when you’re switching it on and off with your foot.
With knobs for volume, compression, treble, attack and release – almost like a studio compressor – you’ve got loads of control over how the compression affects your signal. Setting a longer release time allows long notes to bloom and sustain for longer – ideal for more chilled out basslines.
It’s a really well built, and great sounding, musical compressor – plus it’s a great price.
FAQs
(Image credit: Future)
What should I know when buying a bass compressor?
One consideration to make is how much control you'd like over the effect. Compression can be a bit of a dark art, and really mastering it can take some time, so beginners might want want to opt for something simple that offers more of a ‘set and play’ functionality with just a few knobs, or maybe even a single one. If you know what sound you want, and you either know how to adjust the parameters to get it or you’re well up for the challenge of trying, then look for something with a few more controls on it.
How much should I spend on a bass compressor?
There’s no rule as to how much you should spend on a bass compressor pedal. More expensive models tend to have more features, or will yield a slightly better tone. Really cheap pedals might do the job, but they’re likely to break or fault sooner. Some trustworthy brands to look out for include Boss, MXR, Electro-Harmonix and Aguilar.
As with any pedal, size can matter. We’re all looking to make gigging, practicing and recording easier, and a more compact pedalboard can aid this. A smaller pedal means that it takes less space on your board, so you can either have a smaller board (less to carry), or more pedals (more fun). If space isn’t an issue – maybe you’re only after one or two pedals, or you’ve got plenty of room in the van – or someone carries your gear for you (that’s the dream), then you don’t need to worry about size. You’ll probably find that the bigger pedals will have more functionality and flexibility too.
Do different styles of music need different compressors?
Another thing will be how much you vary the style of music that you play. If you’re flitting between jazz, funk, rock and pop, then a bass compressor pedal with more tweakability will probably be better suited, so you can dial in the right sort of compression for what you’re playing at that time. If you know that you’ll likely be playing similar sorts of music most of the time, then that’s less of a concern.
The sort of tone does vary between the models in our list of best bass compressors. Compressors are used a lot in studios and particular models are lusted after for their unique sound. Some of the above pedals offer the same sort of tone and response as these sought-after compressors, allowing you to have a studio-grade tool on your pedalboard.
