If you’re looking for a pedal that will help you (re)create synth sounds on your guitar, you’ve come to a right place. We’ve taken a gander at catalogs of some of the biggest names in the industry and have compiled a list of the best guitar synth pedals you can find on the market in 2019.

Without any further ado, let’s get straight to it.

Comparison Table of Guitar Synth Pedals

Electro-Harmonix C9 Organ Machine

Electro-Harmonix C9 Organ Machine

Check Current Price
Let’s start off with a big hitter. Basically, C9 continues where B9 left off, and even though these two pedals have a lot in common, they also have some striking differences between them.  If you’re not familiar with what B9 is, it’s essentially C9’s predecessor which came in a similar casing and with similar set of tones.

There are many improvements on the C9 model, starting with the extremely durable and rugged casing. Although this is not a ‘synth’ pedal per se (most people would classify it as a ‘piano’ pedal), it does feature several presets that can easily pass on as synth.

The genuinely intuitive design makes it very easy to use. The control knobs start with the dry signal, over volume, organ, mod (modulation speed), and click (level of percussive attack). You can use the big white wheel to switch between presets, even in the middle of the gig if need be.

Pros:

  • Huge range of strikingly different sound presets
  • Decent effect sustain
  • Intuitive design makes it easy to use
  • Durable casing
  • High value

Cons:

  • Quite expensive
  • Certain presets are more piano-based than synth-based

Earthquaker Devices Data Corruptor

Earthquaker Devices Data Corrupter Modulated...

Check Current Price
Apart from a hillarious name, Earthquaker’s Data Corruptor is a major pedal that will bring plenty of versatility to your tonal arsenal. Though it might not be as easy to use as your average effect pedal, Data Corruptor packs a plethora of synth-like controls spread across four sections (Voice Mixer, Master Oscilator, Subharmonic, and the Frequency Modulator).

Generally speaking, this is basically a fuzz pedal for as long as you stick with the Square line of controls, after which it becomes a synth pedal when you switch over to Subharmonic and Oscilator settings. The Glide/Vibrato switch adds even more wildness to it should you need a little bit of extra chaos on top.

This pedal also has the elements of pitch shifter pedals, meaning that you can shift your tone up or down for several octaves.

The biggest downfalls of this pedal are that it has a big footprint and that the controls aren’t so easy to get accustomed to. With a bit of practice, though, this might become your favorite pedal.

Pros:

  • Exceptionally versatile
  • Total tonal control
  • Perfect for live gigs and studio work
  • Combines the elements of fuzz, synth, and pitch shifter pedals

Cons:

  • Has a big footprint
  • Quite difficult to use

Octavers are some of the finest sub-types of synth pedals, and TC Electronic’s made Sub’N’Up so easy to use that even people who’ve just picked up an axe can play around with it.

Joyo JF-12 Voodoo Octava Guitar Pedal

If you’re on a budget and are looking for a decent synth guitar pedal, Joyo’s JF-12 might just be what you’re after.

This is basically a fuzz pedal which features elements of an octaver onboard. Tone and volume control knobs follow ‘fuzz’ and 2-way mode switch, and even though you can’t go ‘down’ an octave or two, you can go up.

Earthquaker Devices Bit Commander

Check Current Price
Here we have another great pedal by Earthquaker Devices – the Bit Commander. Essentially, this is a monophonic guitar synthesizer which features 4 vintage square-wave synth tones, a small yet very durable housing, and a plain, straightforward interface.

Substracting or adding octaves is all too easy, especially if we compare it to our previous pick (Data Corruptor) – instead of having numerous controls spread out across different sections, there are only six control knobs which follow a logical pattern – level (volume), followed by filter, base, sub (substract octaves), down & up.

There’s also a true-bypass switch which you can use to cut out every other pedal in your chain should the situation demand it.

Pros:

  • Very easy to use
  • Superb tone
  • True bypass
  • Small footprint

Cons:

  • Not exactly as versatile
  • Pricey
