Well, let’s talk about the 10 best vocal harmonizer pedals in 2021!

Vocal Harmonizer pedals are great for singers looking to create additional vocal harmonies in their live performances, which are perfectly in tune with the lead vocal.

These vocal harmonizer pedals are suitable for solo singers and bands, where either, there aren’t any backing singers or the other band members cannot sing.

Vocal Harmonizer effects pedals, also known as vocal harmony pedals are widely used by the majority of current music industry artists looking to recreate their studio recording sound, within their live performance.

We realise that singer/musicians can be highly critical about the sound quality of their vocals, particularly for a solo singer, who cannot afford the privilege of hiding behind a lead guitar part. Vocal Effects Pedals give singers that extra vocal edge, adding to the overall live performance.

Therefore, each of the voice harmonizer pedals we have provided, give the ability for the user to make detailed adjustments and tweaks to the overall vocal sound.

Some of the pedals featured, also integrate with the singer’s secondary instrument (guitar, keyboard) to follow the chords played, accounting for key changes.

We have meticulously researched all of the most up-to-date processors to feature within this list, therefore without further ado, here are the best 10 vocal harmonizer pedals in 2021.

Boss VE-2 Vocal Harmonist Pedal – Editors Pick!

Boss VE-2 Vocal Harmonist Pedal Review, Vocal harmonizer pedal for singers

Main Features/Benefits

  • Great sounding (See Demonstration)
  • Easy to use
  • Integration with Instrument (XLR, 1/4 Jack)
  • Auto ‘Harmony’ Key tracking ability
  • Battery-Powered
  • Can be used without an instrument (Harmony function enabled)

Disadvantages

  • Slightly heavier than other
  • Not got as many features as other pedals (However, don’t get me wrong, this is an ace vocal harmonizer pedal.

Summary

The Boss VE-2 harmonizer pedal combines the sounds of Boss/Roland VE range, providing a high quality, studio-like vocal sound for your live performance (Take a listen to the demonstration video below).

The Boss VE-2 pedal is highly portable and easily stored, being only 600g in weight and relatively small in size.

Alongside the physical aspects of this pedal, making it a great choice due to its portability, it also has the ability to be used entirely on battery power.

A battery-powered stompbox is especially helpful in the live show environment. Whether or not you are busking on a street corner, or playing a staged show, mains plug sockets can be rare to come by, often being reserved by the excessive amount of pedals used by the lead guitarist and bassist.

Now, let’s get to the vocal harmony pedal’s usability features. There are two main pitch settings to keep harmonies synchronised with your lead vocal.

The pedal naturally listens to the chords that you’re playing with your guitar or keyboard, and it can also be manually set to a specific key. Combining these two features will give you the most reliable results.

However, if you have a song which includes a key change, we advise that you do not input the specific key. The Auto-Harmony function is a great addition to this pedal, as we know full well that technicalities should be left to the side once you hit the stage… That’s the time to give your performance!

Also, take a look at our full Boss VE-2 Review here.

For a real look, please refer to the demonstration video below.


TC Helicon VoiceTone H1 – Vocal Harmony

VoiceTone H1 - Vocal Harmony Pedal, Is it the Best Harmonizing pedal for vocalists?

Main Features/Benefits

  • 2 Key controls – Guitar/Instrument or Key/Scale
  • Don’t need an instrument to use
  • Up to 2 harmony voices at any time

Disadvantages

  • No Pitch Correction

Summary

The VoiceTone H1 is one of the cheapest Vocal Harmonizer Pedals, however just because it’s lower in price doesn’t mean it’s lower in quality. In fact, this pedal gives some great sounding vocal harmonies, as you can hear on the demonstration video below.

The user has access to three turnable knobs, giving the ability to choose the songs musical key for the pedal to use, alongside the precise vocal interval for the backing harmony accompaniment. The final knob controls the volume level of which the accompanying harmonies can be heard, relative to the lead vocals.

The main disadvantage of this pedal, against its competitors, is that it’s still as expensive as other pedals on the market, which have more functions.

Also, considering the price, although it is more than half the price of some harmonizer effects pedals featured here, through paying the extra money, you can get an all-in-one vocal solutions processor which could save you money in the long-run, if you were considering purchasing each vocal effect separately.

Conclusion

We realize that many of the pedal on our list are created by TC Helicon. That’s no surprise since they are one of the companies leading the way in voice/vocal effects for singers.

But the Zoom and Boss products provide some great options that should be given some consideration also, with both manufacturers providing products with a lot of different vocal effect options in addition to harmonizing.
