Vocal harmony is used mostly in the choruses of a song, though there are many more places where a second and third voice makes the melody way more expressive.

Some bands are lucky enough to have one or two additional voices that would accompany the leading singer when needed. If that’s not your case, then owning a harmonizer pedal might be the right solution for you. There are a lot of mixed opinions on artificial voice harmonies since they proved to sound a bit robotized

Sadly, the truth cannot be denied: the vocal sounds, produced by a harmonizer pedal are artificial. There’s just no way around it. But there’s a reason why lead musicians keep using harmonizers: artificial harmonies sound totally fine when you hear them along with a lead vocal. Also, every pedal design offers a different set of algorithms to accomplish the given task. Here are the 10 best vocal harmonizer pedals that might help you to achieve the desired vocal sound.

TC Electronics VoiceTone H1

Pro: Compact design and great price/quality ratio
Con: In some occasions, it might be a little slow to adjust to a chord change

Although having a relatively low price, this vocal harmonizer pedal is more than just a starter. It’s simple to use, compact and delivers up to two harmony voices. A proper adjustment of the volume of the harmony vocals is required, since they sound a little bit robotic. Nevertheless, that’s a common issue of vocal harmonizers, hence they’re not meant to be as loud as the lead vocals.

The H1 also throws some hum noise, so consider using a noise gate too. This vocal harmonizer pedal has some unique power requirements. Hence if you’ve got one power supply for all your board pedals, you’ll still be forced to connect the H1 separately, which means that you’ll have more cables, lying on the floor.

DigiTech Vocal 300

Pro: It’s a full vocal processor
Con: Might be both tricky and time-consuming to configure

This DigiTech vocal harmonizer pedal is way more than just a harmonizer; it’s a whole vocal effects processor station. It offers you seven effects slots which include compression, preamp, de-essing, reverb, delay, EQ and 40 factory presets. Even though most of these presets are fit only for a comedy show, there is a handful that might be useful for a professional singer as well.

The metal box of this pedal offers great protection; it has four pedals, two for picking the presets, one for bypass and one for expression control. If you perform live and don’t have a soundman, then this vocal processor might easily save the day.

TC-Helicon Harmony Singer

Pro: Ridiculously simple to use and it also works as a vocal enhancer
Con: No room for tweaks

Many praise the way the TC-Helicon improves the vocals. This TC-Helicon vocal harmonizer pedal comprises an EQ, a compressor, a de-esser and an adjustable reverb. Although not adjustable, these settings prove to work well with many kinds of voices and singing styles.

This pedal is a genuine ‘plug and play’ accessory, since it only takes a minute to adjust the three knobs and start singing. That being said, it doesn’t have a true analog bypass of the main signal; it means that even if you turn all of the settings off, your voice still won’t sound as clean as if it was going directly from your microphone to the mixer

Boss VE-2

Pro: Easy to operate, high quality output audio
Con: Does not come with a power supply

The Boss VE-2 provides high-quality harmonies for your voice. The pedal also looks really fancy, so it might be something you’d like to use when recording with a guest vocalist. Besides having the knobs to adjust the key of the harmonies, you can simply plug in your guitar and the Boss VE-2 will automatically detect the tone and tailor the harmonics according to the chords you’re currently playing… yeah, just like a boss.

The inbuilt ‘memory’ setting allows you to store your presets in an easy way. Besides the knobs, the VE-2 has a pedal to switch between complete bypass, reverb only and full harmonies + reverb.

TC Helicon VoiceLive Play

Pro: It offers many ways to customize the output vocal sound
Con: You’ll constantly need to navigate through pages and pages of settings

Let’s say that the TC VoiceLive Play (VLP) is not a vocal harmonizer pedal in the full sense of that word. Any live musician (especially a guitarist) is used to own pedals that require some knob twisting and there it is – you press the pedal and you know exactly what kind of effect you will get. The VLP is quite different and it probably reflects the modern passion for having everything compressed in one single artifact (a PC or a cellphone).

This vocal harmonizer pedal is something you’d like to have if you’re already familiarized with musical production. Here’s why: you’ll spend more time in front of the VLP’s screen choosing the right settings than actually singing. The pros are evident: if configured properly, this pedal will allow you to bring your live shows to a new level by adding all of the vocal effects you could only have in a recording studio.

The VLP features three external microphones, each one for different purposes and a USB port in order to connect this vocal pedal to the PC and make the desired software updates. It’s more often used by musicians who perform modern pop and electronic music, since it allows you to track the song key from a plugged in MP3 rather than from a connected guitar.

Boss VE-20

Pro: User-friendly interface
Con: Has limited features

Besides harmony, the Boss VE-20 also offers dynamics, double-track, delay, reverb, and other vocal effects. It’s easy to set up and it provides high-quality sound. The main issue of the VE-20 is that it only offers a manual key selection; it doesn’t allow plugging in a guitar and basing the harmonies on the chords. That might be not a big issue if you are used to adjust the tonal key knob for every individual song.

Other than that, this double pedal has a solid and robust metal construction and a high-quality output sound quality.

Digitech VLHM

Pro: Easy-to-use, high-quality output sound
Con: Doesn’t provide a lot of ground for fine-tweaking

If you’re a singer who just wants to sound better in live performances, then the Digitech VLHM might be the vocal harmonizer pedal you were looking for. This pedal have an intuitive and fancy design, which means that most of the desired tweaks can be made by pressing a single button or by twisting a single knob.

You don’t necessarily need to have a guitar plugged into the pedal, since the VLHM has an in-built microphone that reduces the song key from the ambient sounds. Now, if you’re a guitarist, then you might also enjoy the numerous guitar effects this pedal offers.

TC-Helicon VoiceLive 2

Pro: Offers many filter and effect options, including up to 8 harmony voices
Con: It takes time to get used to it

The VoiceLive 2 was specially designed for the ones of you who are fans of tap dancing. Seriously, this vocal harmonizer pedal offers way more real-time control of the effects than just having a couple of pedals to switch between presets. The VoiceLive 2 has ten pedals that offer you total control over the delay, reverb, harmony and other filters.

Many musicians praise the TC-Helicon VoiceLive 2 for the quality of the harmonies it provides. It offers way more than just two harmony voices, so you can easily configure the pedal in order to sound like a Gregorian chant, if needed.

TC-Helicon VoiceLive 3

Pro: Powerful and versatile vocal processor, mixer and recorder
Con: It requires some serious time investment in order to learn how to use it properly

If you’re tired of tap dancing, then the TC-Helicon VoiceLive 3 is the right product for you. It offers a FX automation feature, which allows you to pre-program the way the effects will be activated and deactivated over time.

Honestly, this is more than just a top-quality vocal harmonizing pedal. The VoiceLive 3 can be compared to a mini mixing and recording studio, which allows you to create and store entire songs on the fly, import and export data to your PC via USB, you name it. It also includes a vast set of presets for guitars, so you might consider using it as a fully-equipped pedal board.
