Choosing a Vocal Harmonizer (Buying Guide)

There are so many vocal harmonizers available in the market and they come under different names, with different features and designs. It gets confusing sometimes, so to make the right decision you should first know everything about vocal harmonizer pedals. In this buying guide, I’ll go in-depth about what they are, what each feature does, and how you can use it to enhance your vocals. I’ll also be explaining all the different types in more detail, in addition to some frequently asked questions and what to look out for in general before buying. That way you’ll have all the information you need to confidently make the right decision and choose the vocal harmonizer that fits your unique requirements and budget.

What Is A Vocal Harmonizer?

A vocal harmonizer pedal or a vocal harmony processor is the perfect tool for any musician looking to up their live performance game. In simple terms, it is an audio processor that records your voice in real-time and creates harmonies live as you sing. It allows you to create one or multiple harmonies at the same time with different pitches in realtime. Sounds like magic to your ears right?

A vocal harmonizer can help you recreate your sound recordings in a live setting without backup singers. It can also be a great songwriting tool if you use harmonies as a main vocal production element in your music. What’s great about having a vocal harmonizer with you on stage is that it can be connected to your guitar or keyboard which gives you a safety net for pitch-perfect harmonies and key changes.

Do I Need a Vocal Harmonizer?

A vocal harmonizer is the dream device for many vocalists and musicians. If you’re an artist who wants their live performance to sound similar to their recordings, then harmony plays a huge role in achieving that. And if you’re a singer that is just looking to get creative in their live shows and have a fuller sound then vocal harmonizers may just be the answer for that without needing to have backup singers.

Vocal harmonizer pedals are a creative tool for songwriting, so if you’re looking to have some inspiration while you’re writing and composing your songs, you will benefit greatly from owning a device like that. Vocal harmonizers are great for singers, acoustic artists, bands, and situations where there aren’t any backup singers or even band members who can sing harmonies. I believe that having a vocal harmonizer on stage gives artists an extra flair and adds so much to their live performance, amazing harmonies are always a bonus in my opinion!

Vocal harmonizers aren’t here to cover up bad singing, however, they are a tool to aid in building up talent that’s already there! So if you’re a bad singer, don’t think that getting a harmonizer will cover up the lead vocal. Vocal harmonizers provide a safety net for vocalists during live performances and ensure a professional and consistent sound throughout shows. Overall, it’s an incredible investment for any singer and worth every dime spent.

How To Choose The Right Vocal Harmonizer?

This is a very good question to ask yourself before buying a vocal harmonizer and especially if you have no technical background of pedals and vocal effects processors. To make sure that you choose the right vocal harmonizer, you need to keep in mind a few things. The first thing is your budget and how much you are willing to spend on a tool like this. I’m mentioning budget first thing because with vocal harmonizers, usually a device we’re looking to purchase for one specific purpose, incredible real-time harmonies, you can expect to pay a decent amount especially if you’re looking to a buy a more advanced or higher-end piece. So the first thing to do is keep in mind how much you’re willing to spend.

The second thing to think about, and be honest with yourself here, is how integral it is to your performance or studio use, and how frequently you will be using it. If the vocal harmonizer will be a huge component of your performance or songwriting then by all means do invest in a good one that will stay with you for years. You want to keep in mind its durability, weight, and size especially if you’re planning on taking it with you on the road!

Another factor is how many extra features you want, this will also determine the price of the model. If you’re looking for something basic with minimal features, chances are you’ll find pretty durable and affordable models. However, if you want more advanced harmonies, controls, and a ton of other features to play around with, then be willing to pay the extra price, but be sure it will be worth it with a device like that.

If you’re a professional or amateur guitar or keyboard player, you should look for a pedal type harmonizer which connects to your instrument and lets you control your harmonies with a foot-switch. This is essential as it will determine your performance setup and mobility on stage. If you’re a singer and don’t play any instruments maybe you can opt for a mount type of vocal harmonizer which attaches to your mic stand. You may still be able to connect it to any of your band members’ instruments for more accurate harmonies determined by the chords, but you’d be able to control everything with the touch of a button. It all depends on your live setup and how you want to be controlling the harmonies, so please keep that huge factor in mind while narrowing down your picks.

The last thing to ask yourself, and probably the most important in this case, is what are the harmonies offered. Before buying a vocal harmonizer you should be sure of the type of harmonies you’re getting. Each brand offers different settings and controls for this feature, however, they all can provide you with neutral harmonies. In my reviews, I help you find the harmony features you are looking for, so just by reading this article, you’ll be able to determine which brand and model is best for the type of harmonies you want.

What Are The Main Features To Look Out For?

By reading this article, you can see that vocal harmonizers come in so many different shapes, sizes, and with so many controls and features! It can be confusing to tell the difference between them and make the right choice, especially when they all sound very similar in what they offer. That is why it’s really important to understand the main features you should be looking for and what will make a world of a difference in your decision making.

Below, I’ve mentioned the main features to look out for while buying your vocal harmonizer, however, you should also make sure you are getting one with smooth reliable knobs or switches, with clear harmonies and good sound quality. Having said that, here are the main features you want to have in your vocal harmonizer:

Harmonies: Harmonies are the main reason you want to buy a vocal harmonizer so you need to make sure the sound quality is great! You can do that by watching videos of musicians using the vocal harmonizer to hear the sound quality. Some vocal harmonizers allow you to plug in your guitar or keyboard which produces the right harmonies in real-time based on the chords being played. The output is pitch-perfect as the harmonizer uses notes from the chords you play and doesn’t require any interference from your end.

Some harmonizers’ harmony output is more towards the “feminine” or “masculine” sound, so this is vital to consider while making your choice. You also want to make sure you get a vocal harmonizer that will let you add multiple harmonies and gives you control over them. The more harmonies and advanced controls you have in a vocal harmonizer, the better. This differs from one model to another, but the best ones are the ones that give you plenty to work with!

Tracking: Tracking is what a vocal harmonizer does to be able to match your voice with the right-pitched harmonies. A vocal harmonizer tracks the chords you play with your instrument in real-time and produces harmonies to match.

Some harmonizers track what you are playing and others let you manually select the key which could be a needed safety net in case any issues happen with instrument tracking. For example, you set the key, and the harmonizer can figure out which note you’re singing, and then creates matching harmonies in real-time. However, most vocal harmonizers nowadays have powerful and advanced processing and have perfect tracking abilities and pitch correction.

Gender Shifting: If you want a vocal harmonizer that creates harmonies that suit your voice perfectly, you need to pay attention to how effective it is with gender shifting. Gender shifting is the harmonizer’s ability to shift to a feminine or masculine tone of voice. The gender shifting or “pitch shifting” is also a cool feature to have if you want your voice to sound deep or high, depending on your performance. This is a feature that you should keep in mind because it can make or break your live performance!

Inputs and Outputs: For the average singer who’s looking to buy a vocal harmonizer, a normal XLR connection should suffice, but if you play an instrument or have a band playing with you then you’d need inputs/outputs that would give you the flexibility of connecting any instrument. Also if you need to use a different pre-amp or would need additional channels, I’d recommend that you think about your live setup and the equipment you have on stage and make sure the vocal harmonizer you decide on has inputs/outputs that are compatible.

User interface and Controls: For me personally, the user interface and layout is a priority in any vocal harmonizer or processor that I buy. I need to be able to have a simple and easy experience navigating and controlling all the features and knobs. If it’s overly complicated and doesn’t have a user-friendly interface, it’s really easy to get lost and confused and you end up not getting the most out of your vocal harmonizer. If you have a lot of presets and different harmony effects for different songs in your set, you should consider a harmonizer with an easy layout.

Additionally, If you’re playing the guitar, you should make sure you have a “stompbox” pedal which you can easily control with your foot. Even if you don’t play an instrument, you should think about how much you want to be moving on stage and see which vocal harmonizer won’t be too distracting and gives you that flexibility.

Other Effects: Vocal harmonizers also come with multiple effects, especially if they are designed to be more of multi-effects vocal processors. This means that in most cases you get much more than just harmonies! For a live performance, this can be extremely beneficial but if you’re using it in the studio or for songwriting then you don’t need one with multiple effects.

If you’re looking to go wild with your vocal effects then go for a well-rounded multi-effect vocal processor (check out our article about vocal effects processors). But If you’re only buying a vocal harmonizer for the harmonies and pitch correction, then a more simple and focused one would be more than enough for you!

Here are some simple and basic effects I would keep in mind when buying a vocal harmonizer for live performance:

Reverbs & Delays:

Most vocal harmonizer pedals and vocal effects processors come with basic effects like reverb and delay. This is especially important to have when you are performing live. You want to have only one pedal for efficiency and to have a good mix you will almost always need a little bit of reverb and delay to spice up your vocals. Usually, the manufacturer’s signature reverb and delay pedal sounds are included in the harmonizer, so that’s a big plus to save some space and be more efficient on stage!

EQ, Compression, and Pitch Correction:

Most vocal harmonizers come with adaptive tone technology which automatically applies EQ, De-Esser, and corrects your pitch as you sing. Most vocal harmony processors’ manufacturers include adaptive tone technology, however, one of the most advanced in this area is TC Helicon. When you are performing it’s always good to have these effects automated instead of manually controlling them live which can be a bit of a hassle. Pitch correction enhances your overall live sound and the more it lets you control the tuning, the more customized sound output you’ll get.

General Things To Keep in Mind:

Choosing the best vocal harmonizer for your live performance or the studio solely depends on how you are going to use it and how frequently. Here are some questions to ask yourself when you’re deciding on a vocal harmonizer. What does your live setup look like? Are your songs recorded with many harmonies and you want to recreate them live? Do you have backup singers or do you prefer performing solo? Do you want one harmony line or the option to have multiple different harmonies at the same time? Do you play the guitar or keyboard or will you be singing only? Do you prefer controlling the pedal with your foot or would you prefer a stand mountable divide to see everything played out in front of you? Do you need other effects with your vocal harmonizer for your live performance or would you prefer a device that focuses only on producing harmonies? Asking yourself these questions will determine which type of vocal harmonizer is the right one for you.

Whatever vocal harmony processor or multi-effect pedal you end up choosing, it’s important to know that the more it lets you control the settings of each effect, the better. You’ll have the ability to customize your sound and utilize the device in a way that’s unique to you and depending on your live setup and sound, you can find something that suits you.

Also keep in mind the size, weight, and durability of your vocal harmonizer while making your choice. Make sure you pick something that would be suitable to take on the road with you and will stand the test of time.

Finally, don’t hesitate to invest in a device like a vocal harmonizer. Usually, you buy a vocal harmonizer and it stays with you for years on end, it’s not something you keep upgrading like other instruments and in this case really, the more you pay the more value you get for your money.


Vocal harmonizers have the ability to transform your performance. Although there are not many inexpensive ones out there, you get value for your money, especially with today’s models. You get harmonies, pitch correction, and basic effects like reverb and delay, what more can a singer want? With that being said, two manufacturers lead the way in this niche, and those are Boss and TC Helicon, I can’t recommend them enough. Their overall practicality and advanced technology and controls have separated them from the rest of the bunch! Now that you have all the information, I hope that this article has helped you decide on which vocal harmonizer to invest in. Good luck!

  1. Great review, thanks.
    I wonder if you can tell me…….on the units that have two outputs – a ‘mono’ and a ‘dry’ – does this mean the original dry vocal signal and the harmonies can be sent to separate channels on the mixer?
