Bass Synth Pedals – 12 Best Synthesizer Pedals for Bass (Review 2020)


 Cool, right? Here is a breakdown of each down below.

2020 Cheatsheet Of The Top 10 Bass Synth Pedals

  1. Best Overall; BOSS SYB-5 Bass Synthesizer Pedal

The BOSS SYBE-5 considers price, synthesizing quality, durability, and efficiency, all of which give it a place in the first position on the list. This is one of BOSS’s first bass synth pedals to ever make it to the market for the professional bassists. The SYB-5 is one of the most highly durable and portable pedals for all stage performers looking for a heavy-duty stimulator that performs stably through hours of gigging without dying out unexpectedly.

 And just because it is BOSS-made you get 5-years warranty coverage on a high-quality effects pedal. Cool, right? Well, here’s more. At the bottom line, all you need to power it up right out of the box is a dry 9V battery. And did I mention the control filter cutoff feature that puts you more in charge of your production, allowing you to dynamically finetune your frequencies?

See the complete features, pros, and cons below. Or just go for it already to avoid going through the technical mumbo jumbo.

  1. Big Budget Pick; Electro-Harmonix Bass Micro Synthesizer

If you have enough dollars to throw around, this is one bass synth pedal for the road whenever sound quality matters (sure it always does). Electro-Harmonix is a highly capable analog-based bass synth pedal offering more than the popular lead synth pedals can offer in sound. It features 4 main synth voices; square wave, guitar, octave, and sub-octave, all of which can be tweaked for modification by engaging the integrated envelope and filter sweep controls to sound more than just sound well.

 This way you can craft a personalized bass sound for the event. Though this pedal has enough effects for a performing DJ, I wouldn’t recommend it for live performance for the fact that you can’t save patches on it. It has no storage space and you’ll have to make changes manually all the time you need to mix. Other than that, perhaps you may find a way around this little snag, this is a quality bass micro synthesizer for the money. Check the full picture below as illustrated in the specifications list.

For one, there’s the compressor/limiter functionality for a versatile setup of your effects. Then again, there’s the drive/synth feature to add more color to your low-end tones.

 Other included features are; master, filter/tone, expression, delay/modulation. These and more allows you to fashion a wider spectrum of powerful and unique tones for the event under consideration. More than just a bass synth, BOSS ME-50B adds sound hold effects, kickdrum effects, and octave to what it offers.

This white-and-red stylish pedal offers two main voice synth functionalities that are engaged via a responsive toggle switch at the top of the pedal for a quick location.

 And thanks to the 4 interface knobs, you make dynamic editing of the aforementioned two main voicing synths; wash voicing and vocal formant synthesis respectively. My final verdict is, if you’re expecting to play mono and stereo along the line, this pedal is consistent in quality sound delivery. The only downside is that you can’t save patches anywhere on it.

 Also, if your guitar is such that doesn’t have pickups this portable box will do the trick even without you having to implement MIDI in your setup. Though not an ideal unit for your 34” scale guitar, if you’re looking for a bass synth with an extended tracking range that reaches the 23rd fret on the high E string, this is a great choice. It will also track the open A-string on your bass guitar consistently without mudding your production.

  1. Heavy-duty; MOOF MF101 MoogerFooger

The MOOF MF101 is a heavy-duty unit that will work any instrument-level you set it up for. It is a low pass filter with two modular functions namely; an envelope follower and a voltage-controlled low pass filter. All of the low pass filter parameters foot-controlled or controlled on an external control voltage or even on the tweaking knobs dedicated to that.


Once the configuration is done, the low pass filter finetunes and makes your tones mellow or muted by removing all the unwanted high frequencies whilst boosting all the frequencies that are near the cutoff. Finally, as there’s an envelope follower that tracks and follows the loudness contour of your sound to control the bypass filter by opening and closing it, you automatically play the filter as you play your instrument. See the complete features, pros, and cons below for the bigger picture.

  1. Best For Keyboard; Electro-Harmonix Blurst Modulated Filter Pedal

Whilst the Electro-Harmonix Blurst is a modulation filter for guitarists, bassists most especially, it is a more useful synthesizer for keyboardists. For the adventurous guitarists, this pedal modulates basses and electric guitars, making them sound like envelope filters. But in this case, the filter isn’t controlled by playing dynamics but, otherwise, by an internal oscillator that does the filter response control on autopilot as you play.

 Electro-Harmonix Blurst modulated filter spots an analog, low pass filter that includes an adjustable resonance. On top of that, it offers 3 modulations namely; waveform shapes, tempo, and expression pedal control. You can use it as a standalone or set it up in a chain and it still performs in an outstanding way. The needed power supply charger is included in the package so you don’t have to spend more.

  • Resonance
  • Bypass filter
