And that becomes a disadvantage when you’re standing before an audience sweeping through your laptop or your mobile phone for control.


  • True bypass
  • 1 ¼” input jack
  • 1 ¼” output jack
  • Die-cast metal case
  • TonePrint app

  1. Studio Choice; Seymour Duncan Studio Bass Compressor

If you’re making this purchase for your studio production, this is the best compressor for slap and kick in the studio. Seymour Duncan is a powerful studio compressor for both active and passive guitars.

Seymour Duncan Studio Bass Compressor Pedal Bass Compression Effect Pedal

This is one of the best VCA-based bass compressor pedals infused with studio standard circuitries and internals for a punchy, clean low-end tone. It applies an almost equal simplistic approach like Keeley which I have reviewed previously, but this time, Seymour Duncan gives you 4 functionalities to configure as you wish. First off, there’s the compression control to craft the ideal compression ratio for your signal which is then ramped up or down via a volume control. Finally, you can decide the amount of color you want to add to your dry signal with blend control and after that, you get to set up the attack dynamically.


  • Compression ratio range; 1:1-20:1

  1. Vintage Compressor; Electro Harmonix Classics Black Finger

The Electro Harmonic Classics Black Finger presents a professional classic portable compression in a dark toroidal transformer-based pedal with a full swing of 300V.

Electro-Harmonix Key 9 Electric Piano Machine , Power Supply included

This compressor pedal with its fantastic sustain will shell out a sweet and warm musical tone for your acoustic guitars and basses by allowing you to add more vintage color and distortion to your sound. Here’s a sneak peek of how it does its job. First, your raw signals are driven harder into the compressor so that they get broken up into choppy distorted sounds for better compression. And once compression is done in the two 12AX7 vacuum tubes, you can proceed to add volume and gains to suit your need. Yes, as simple as that. But the sound quality you get is superior to most other so-called best bass compressor pedals.


  • Dual-tube compression; 1AX7
  • 300V full swing
  • Adapter; 12VAC/1000mA
  • Post-gain control
  • Pre-gain control
  • LED/LAMP switch
  • NORM/SQSH switch
  • Automatic gain control
  • Level LED
  • Status LED
  • Compress knob


  • Quality squashed profile
  • Clean normal profile
  • Stable dual-compression circuit
  • Tight pre-gain and post-gain


  • Not the easiest to use for beginners

  1. Most Dynamic; Darkglass Hyper Luminal Bass Compressor

Hyper Luminal is a 9V vacuum-based compressor pedal, highly dynamic for both active and passive heavy metal. In the same box, you get 3 distinct modes of compressions namely; SYM, FET, and BUS. If you’ve ever used Darkglass’s Supersymmetry 115 GeV compressor with your instrument, well, the SYM mode of this compressor is a representation of that oldie.

Darkglass Hyper Luminal Bass Compressor Pedal

The BUS mode, on the other hand, stands for Darkglass’s Solid State Logic Bus compressor. And finally, the FET is modeled after the very ancient 1176 FET compressor. All of these three modes can be activated one after the other on a stereo-like control that makes activation easier. And finally, you can adjust the amount of compression on each mode through 4 distinct ratios of compression and even time-schedule the attack and release features. Needless to say, Hyper Luminal Bass Compressor offers a blend functionality so you can mix colored and raw signals together on the fly. See the complete features, pros, and cons below.


  • BUS, FET, and SYM compression modes
  • 4-level compression ratio
  • Output gain control
  • Blend
  • Current usage; 250mA
  • Gain reduction
  • 1 ¼” input jack
  • 1 ¼” output jack
  • VCA control


  • An authentic VCA/FET-based pedal
  • 3 compressors in one useful place
  • The first hybrid compressor in history
  • Easy to use gain reduction function
  • Real-time attack and release timing

Finally, as promised, see below for my discussions on the hottest topics about the best bass compressor pedals.

Guitar VS Bass Compressor

There’s no much of a difference between the two, actually. They both perform the same function of compression. Think about the fact that Tony Levin uses a guitar compressor (Analogman Juicer) for his bass and that the majority of guitar players use the MXR M87 bass comp, which is, of course, a bass compressor. Nevertheless, though not a silver lining, the compression or release ratio of bass comps are pretty higher when compared to that of guitar compressors. Besides, it’s useless to have a low compression ratio bass comp in the real sense.

Why Do Bassists Use Compressors

Let’s get this straight from the bottom up. The sole purpose of compressors is to squeeze and compress the dynamic range of a signal, reducing the volume passage space of bass signals so that your signals come out boosted having passed through a slim passage. So the reason bassists use compressors is to balance out dynamic playing styles like a slap or a kick, add a smooth glassy tone, and make the bass signal punchier to the listener. At the bottom line, bass compressor pedals will help you create a lot of headroom for your listeners. This is especially important for a stage performer or a studio producer. So if you’re asking what does a compressor pedal do for bass or is a bass compressor necessary, there you have it.

How To Set Up Yor Bass Compressor

So, suppose you were going to give a handful of bass compressor pedals a position in your chain, what is the best position? The first. Yes, that’s right because you want to have the compression done right off the bat of your bass before adding other effects. Nevertheless, there are some specially designed bass compression pedals that are highly dynamic enough to be placed anywhere in your chain. But in my own opinion, the best place to always put your compressor pedals in a chain is right next to your bass.


Bass compressors are a must-have in the rig of every bassist, and most especially for the modern bassist. They simplify the process of boosting your raw bass and even allow you to create dynamic tones. But choosing from the tens of brands and the hundreds of models on the market may turn out to be daunting. To make it a walk in the park, I have handpicked, suggested, and reviewed some of the top quality models available at your budget. I can only hope that you’re finally able to decide on which of them is the best bass compressor pedal for your needs.
