As vocal harmonizer pedals go, the Boss VE-20 is among the best when it comes to embellishing artists’ live performances. This classic vocal processor pedal is a go-to stompbox for many musicians that offers useful, good-sounding, and necessary effects.

Pros

  • Sturdy, durable construction
  • On-board phrase looper
  • Versatile pedal with many great effects
  • Exceptional harmonies

Cons

  • No guitar input
  • Cannot save loops

The Boss VE-20 is a more-than-capable vocal harmonizer that offers 3-part harmonies. In addition to having reverb, delay, and real-time pitch correction, it also has a phrase looper with 38 seconds of recording time. The only letdown is that you can’t save your loops.

You can easily layer your vocals while adding harmonies to make your live performance sound classic, full, and richer. Additionally, the pedal is quite durable so any traveling and carrying around will not be a problem.

Pedal TypeVocal processor
EffectsDelay, Reverb, Distortion, 3-part Harmony

One of the major drawbacks to this pedal is the lack of guitar input, however, it does have a microphone and headphone input. Overall, regarding performance, the Boss VE-20 is a superb vocal harmonizer for upping your live performance.

2. TC Helicon VOICETONE H1

Budget Pick
Affordable vocal harmonizer pedal with high-quality harmonies and a sturdy design.
View Price at SweetwaterView Price at Amazon

TC-Helicon’s VoiceTone H1 is an affordable vocal harmonizer that offers rich one or two-part harmonies to your vocal performance. Due to the guitar-sensing technology built-in, the pedal fine-tunes your harmonies in real-time.

Pros

  • Rich, high-quality harmonies
  • Modest price tag
  • Easy-to-use pedal
  • Preamp gain control

Cons

  • Not as good for low-end harmonies
  • Not battery-powered

What makes the VoiceTone H1 a good vocal harmonizer is the one or two-voice harmony selection as well as the guitar-sensing tech that tunes your harmonies live. Additionally, you have a mic preamp gain which is not something you see much on vocal harmonizers.

The pedal is also fairly durable, sporting a sturdy yet aesthetic design that is quite easy and straightforward to use. You can also chain-connect the pedal to other VoiceTone Singles and amp up your live or studio performance.

Pedal TypeVocal harmonizer
EffectsDry/Wet, 1/2-voice Harmony

View Price at SweetwaterView Price at Amazon

Another classic Boss pedal on this list, the Boss VE-2 is a heavyweight among vocal harmonizers due to its durable construction, 24 harmonies, and additional vocal effects for live performers.

Pros

  • Simple, easy-to-use interface
  • Durable construction
  • Superb harmonies
  • Useful effects with a single knob

Cons

  • Not as fancy as other options
  • Not as good when you combine guitar and vocals

This simple, easy-to-use pedal sports a sturdy, no-frills design and offers 24 harmony types, reverb, and delay effects. Although, when you combine both a guitar and vocal sound, the harmonies tend to muddy up a bit so it’s best to use one or the other, despite the infamous hybrid mode that follows the manual key setting.

The pedal features a slight, subtle pitch corrector while singing live and controls your dynamics sort of in a way a compression feature would. It also has three memory slots for storing your settings and even has an Auto Harmony function.

Pedal TypeVocal processor
EffectsReverb, delay, combo
Power9V DC adapter, 4 x AA batteries
Bonus FeaturesAuto Harmony mode, Hybrid mode

All in all, the Boss VE-2 is a good tool for live or studio performers that adds that extra polish to your sound and features many harmony types, effects, and user modes. For a modest price tag, this heavyweight pedal is worth considering. An honorable mention would also be the Boss VE-8 Acoustic singer.

The value-for-price ratio is exceptional here, however, it does have its downsides like the short loop time and the lack of memory slots. Furthermore, it has a bit of a steep learning curve and requires a bit of fiddling around to get the preferred sound and setting. With many features to choose from, it can be overwhelming.

Pros

  • Easy-to-use device

  • On-board compressor

Cons

  • Not the best highs

The pedal boasts many cool features, all for a modest price tag. It has onboard compression, EQ, noise gate, and even de-essing. Not only that, but the simplistic design adds that much more value as it only features 3 knobs and a dedicated footswitch.

The Reverb knob offers 3 separate reverb settings that include Club, Hall, and Rm. With the Harmony knob, you can choose between 8 different harmony types and control the Level with the third knob. Pretty simple yet very effective!

Pedal TypeVocal processor

While the pedal lacks a bit of detail when it comes to the highs, it is still a decent vocal harmonizer for musicians. Granted, the build quality falls short of other options on this list, however, the price tag all but makes up for it.

What is a Vocal Harmonizer Pedal and how does it work?

A vocal harmonizer pedal is basically a backup singer in a box. When you sing through this device and fiddle around with the harmony controls, you get amazing harmonies in real-time, as if you have a backup singer with you. Some even have pitch correction (auto-tune) effects and octave control to embellish your performance even further.

Do you need a Vocal Harmonizer Pedal?

A vocal harmonizer is by no means a must for musicians but it’s a very GOOD addition to any performance, especially for solo acts. Since these pedals are somewhat moderately priced, any solo performer can boost their performance by adding angelic harmonies, vocal effects, EQ, compression, and other effects/features.

What to look for in a Vocal Harmonizer Pedal when buying?

There are a few things to consider before purchasing a vocal harmonizer pedal like the sound quality, onboard effects, useful features, and the price.

The sound quality should be your main concern. Reputable manufacturers like Boss and Electro-Harmonix have been in the game and are known for producing good-quality pedals with excellent sound detail. The best you can do is test out any vocal harmonizer for yourself. Visit a local music shop and hear the sound firsthand.

Secondly, you should always consider the onboard effects and features of the pedal. You’d want some vocal effects like reverb, and delay, as well as some cool additions like a mic preamp, EQ, compression, etc.

Lastly, the price is well worth considering. If you’re just starting out, many great budget-friendly vocal harmonizers will get the job done. However, if you’re a solo performer with many years of performing under your belt, consider upgrading and purchasing a more high-end pedal with more features and effects to up your game.

Summary

Vocal harmonizers embellish your performance by adding harmonies and effects to your vocals or instrument. There are many great harmonizer pedals on the market that offer a lot of features and effects within a reasonable price range. Not only can you up your vocal performance but you can also connect other instruments like guitars and keyboards to reach new heights.

My top pick is the Boss VE-20, a versatile vocal harmonizer with 3-part harmony and various other vocal effects.

My budget pick is the TC Helicon VOICETONE H1, an affordable pedal that offers a good signal path and high-quality harmonies.
