Incorporating a synthesizer pedal into your bass's arsenal of sound can be one of the best options available for to you to achieve that special dashed sound that most bassists only get to desire.

Thanks to these implements you will be able to explore all the potentialities of your bass, in addition, they are usually very complete, helping to save space on the pedalboard.

Most Bass Synth Pedals are useful for both live performances and recordings because they give you more control over your final sound output.

And since the options are just limitless, we decided to bring you a list of the best options in Bass Synth Pedals that are available out there:

BOSS SYB-5 Bass Synth Pedal

Thanks to its 4 knobs that control different effects, you can create with this pedal some really extravagant sounds, limited only by your imagination.

If we consider its size it is a very versatile pedal, besides being built to last a long time.

The BOSS SYB-5 pedal, manufactured by the reliable BOSS brand, has two inputs and outputs to process two signals at the same time, although under this mode one of them is always active. In addition, the hammers and starts are improved in this version, the ghost notes disappear, but without the expression pedal or TRS, you won’t achieve too much when it comes to power.

When you connect the expression pedal –an optional EV-5 pedal is recommended- you will have access to a large number of synthesized sounds, although we recommend that you start with the configuration suggested in the manual.

Pro's of the product

  • Sturdy construction.
  • True
  • 11 variations of DSP saw, square, and pulse Synth

Cons of the product

  • It may be a bit slow in following up, you can omit some notes if you try quick
  • Without an expression pedal, it is not very
  • Despite including a user manual, it is not easy to learn how to use

Electro - Harmonix Micro Bass Synthesizer

While being an expensive pedal, this Electro- Harmonix synthesizer is at the professional level in performance.

The four voices settings –Guitar, octave, sub-octave and square wave- are completely independent and mixable, and they can also be modified to a greater degree with filter sweeping and enveloping controls, which are particularly useful for those who love disco music.

The Electro- Harmonix model is capable of performing the work of different pedals, in a single device.

On the downside, it is quite big compared to other pedals of this type and does not store configurations, so it is not a good choice for presentations where you need to adjust between songs or aim to switch between double effects.

Naturally, you will need to invest enough time to know the operability and capacity of a pedal with so many adjustments and, although it incorporates different functions, it is not a bad idea to own other pedals –Like a compressor, octave, or distortion effect- to combine.

Pro's of the product

  • 10 sliding controls for a variety of effects, including Trigger, Sub- Octave, Guitar, Octave, Square Wave, Attack, Delay, Resonance, Start Frequency, Stop Frequency and Rate.

  • Extremely versatile

Cons of the product

  • Occupies a lot of space on your pedalboard.
  • High price.
  • Does not store configurations.

DigiTech Dirty Robot Stereo Mini-Synth Pedal

DigiTech brings to the table a simple but really useful pedal.

It is designed to be used with both bass and electric guitars, so it is ideal for those looking for a versatile synthesizer processor for instruments.

Dirty Robot also has a 360-degree interface to combine Sub, Square, and Octave sound landscapes that can be really useful for techno and dance bass players.

This model is overall perfect for those seeking a 12-string sound close enough to the real thing, which can be used in both recordings and live performances, but without the drawbacks that involves using a real 12-string guitar in such situations.

On the downside, you will find a slight delay that emulates the natural sound of hitting a pair of strings on a 12-string guitar.

Pro's of the product

  • Selector to activate two different synthesis modes.
  • LED indicator.

Electro - Harmonix Blurts Modulated Filter Pedal

The Electro- Harmonix Blurts is essentially an over-elaborated Tempo pedal.

Unlike other synthesizers, this is not characterized by manipulating the notes aiming to get the effect of 12 strings or sub-octaves.

It does, however, offer the great attribute of Tempo manipulation, which works excellently, although you will need an expression pedal to get the best from it.

This pedal is designed specifically for bassists, guitarists, and keyboard players. It has a low-pass form of modulation wave with adjustable resonance, three analog forms, tap tempo, and a range control rate.
