Have you heard of using vocal harmonizer pedals during your performance? If you haven’t had a go on a vocal harmonizer pedal yet you are going to want to give it a try as a lot of vocalists are now incorporating this handy piece of equipment into their live performances.
A vocal harmonizer pedal not only produces real-time harmonies but can be used during live performance and recording as it has the potential to be hooked up to other equipment.
In this article, we will explore exactly what a vocal harmonizer pedal does and which are the best vocal harmonizer pedals on the market today.
What Is a Vocal Harmonizer?
You may have heard about vocal harmonizer plugins but you can now get that clever harmonizing technology in a pedal designed for vocalists to use when recording and at live events.
A vocal harmonizer pedal will be able to add harmonies of different intervals to your voice in real-time based on the vocal and instrumental input. There are even pedals on the market that do not require any instrument plug-in to be able to determine which key you are singing in in real-time.
Even though the harmony pedals create artificial harmonies on your voice, depending on which pedal you get these harmonies can sound very natural, especially during live performance.
How Does a Voice Harmony Pedal Work?
Knowing how to use a harmony pedal really depends on what kind of pedal you get. The easiest harmony pedals to use are the ones that are built only for producing harmony on the voice as they have minimal settings and are quick to set up.
How to Use a Vocal Harmonizer Pedal
To use a harmony pedal you will need to connect your microphone as an input to your pedal and have the output as either an amplifier or an interface to be able to record.

Why Are Vocal Harmony Pedals So in Demand?
If you have been aiming to purchase a vocal harmonizer pedal online, you may notice that for some brands you are having to wait for a little longer in order to get your vocal harmonizer pedal.
This is due to two reasons:
- Popularity
- Issues with parts
Popularity
Everybody now wants to use vocal pedals as there has been a big growth in the industry in the last few years and also a big growth in the development of the technology. The technology of vocal pedals has now become more advanced and more reliable when applied to the voice.
Issues with Parts
Due to changes in policies across the world, the parts to make the pedals have become difficult to source. Sometimes, it can be the smallest part of a pedal that becomes unavailable which means the pedal can not be made in the production stage. Due to this issue, there is now a backlog of orders.
FAQs (Frequently Asked Questions)
This is a very tricky question to answer as it really depends on what you are personally looking for. What use you will get out of your pedal will determine which brand and model you go for. Our pick would be the TC Helicon VoiceTone Single H1 Intelligent Harmony as this pedal not only produces fantastic harmonies but is reliable without a guitar input.
A vocal harmonizer works by recording the sound of your voice or guitar in real-time and adding harmonies of selected intervals to that original vocal input. The harmonies are created by the incoming audio and can then generate harmonies that are of different pitches.
The best way to add harmony to your voice is to either sing with other vocalists, record yourself singing the different parts or use a harmony pedal.
When singing, applying harmony means adding the sound of either two or three notes simultaneously. These notes can either be above or below the main notes. Harmony can be made up of more than three parts but it will always be called harmony.
Final Thoughts – Choose the Pedal That Covers Your Basic Needs
There are a lot of vocal harmonizer pedals that are on the market and range in different prices. Even though some of the vocal harmonizer pedals have a lot of extra features that are impressive, I would recommend that you choose the vocal pedal that will fit your needs. Going for an expensive piece of equipment that does way more than you’re asking for can be a hassle rather than a blessing.
It will take time to set up something so complicated. I would recommend that you decide where you would like to use your pedal and choose a pedal that ticks all the basic needs. TC Helicon produces the most natural-sounding harmonies but BOSS has some great pedals that work for vocalists who do not play another instrument.
