What is a Harmonizer Pedal?

A harmonizer pedal is a pedal that allows you to add harmonies to your guitar (sometimes automatically), and they may include reverb, pitch shifting, echo, and other effects. They often have a footswitch so you can turn it on and off during live performances. 

They are a great asset and highly valued by guitar players all around the world. Have a look in the sections below for a more detailed insight into how a harmonizer works and what features a high-quality one should include. 

How Does a Harmonizer Pedal Work?

The harmonizer effect for guitar is a subcategory of the pitch effect where the pitch of tone gets lower or higher. Harmonizers, unlike octave pedals, for instance, can transpose any number of intervals, not only octaves. 

The pedal works by keeping the original sound and combining it with a duplicated version, which is pitch-shifted. The result is a harmony of tunes that play together perfectly synchronized with a thicker tone and soundscape, transporting your listeners into a sonic nirvana. 

Are All Harmonizer Pedals the Same?

Just like all the other effect pedals, harmonizer pedals do suffer some variations from model to model. The section below will give you a more in-depth insight into the features of the best harmonizer pedals on the market. 

The main difference is that there are vocal harmonizer pedals – which have features not directly affecting your instrument, and they can be a lot more expensive because of this. Some of them, most modern models, include key tracking abilities, which makes sure the performance is glitch-free. 

Why Did These Pedals Make Our List?

Here are some of the main considerations we took into account when providing you with the top recommendations:

High-Quality

The prime consideration is, of course, the high-quality of the product regardless of its functions. Some are simpler, others more complex, but they all have to give a glitch-free performance, otherwise, your songs will be out of tune and not so pleasing to your audience. Thus, they are all thoroughly scanned for consistent sound quality.

Extra Features

Some extra features are a nice addition to your gear – meaning you can do more with less. Some models only offer harmonization, but we included other units that allow pitch correction, doubling, and others, which become really useful if you are a gigging musician. You can easily create layered professional-quality tunes. 

Ease of Use

Lastly, there’s no bigger frustration than investing your money into a pedal you cannot use when you’re performing. For this reason, we did our best to scrutinize design imperfections and provide you with a genuine, objective review of these pedals. This comes as a primary consideration for professional use. Some budget-friendly options with minor flaws are also available for beginner use. 

Review of the Best Guitar Harmonizer Pedals

Without further ado, let’s take a look at some of the best harmonizer pedals available on the market to get you started with your search.

TC Electronic Quintessence Harmonizer (960827001)

PROS

  • Can easily nuance your tones
  • High sound quality with no glitches
  • Easy to choose between intervals/modes
  • Allows the creation of intricate harmonies
  • Has separate mono/stereo inputs and outputs

CONS

  • Buttons are very small
  • No distinction over minor/major sounds
  • Can be tricky to use quickly, feels quite flimsy in a rush

What Recent Buyers Report

This harmonizer processes beautiful sounds and effects and keeps them clean and clear no matter how complicated the harmonies are. You also have extra control over the nuances of your sound due to the dual input/output feature, which allows for mono or stereo sounds. 

Why it Stands Out to Us

This harmonizer pedal is a top-notch intelligence unit that includes both MASH technology and TonePrint. MASH technology is specially created to allow greater pressure sensitivity of the footswitch, thus increasing ease of use. TonePrint editing features a wide range of choices and high flexibility. 

Who Will Use This Most

This product is great for beginners, and it is highly flexible. It can be used with any music style and genre, ranging from country/southern rock harmonies to metal leads. Any harmonies you might need, this unit is the ideal companion of all guitarists. 

Bottom Line

The Quintessence harmonizer offers state of the art technology, revolutionizing the industry. You can create any harmony you wish, whether simpler or more intricate, with ease. On the other hand, the design is quite small and hard to manipulate in a rush, although you will get there with a bit of practice.

DigiTech Whammy

PROS

  • Wide range of pitch-shifting effects
  • Sturdy design, rock-solid and reliable
  • Quick responses and flawless tracking
  • Momentary footswitch ideal for creative riffs and licks
  • Drop Tune is great for live performances to switch to lower tunings

CONS

  • Large casing 
  • Selecting effects can be quite difficult
  • Quick riffing can be glitchy at times

What Recent Buyers Report

This pedal is built like a rock, so it might take up quite a bit of space on your pedalboard. Despite this, the features on this pedal are amazing – the Whammy/Monetary footswitches are well placed, and you can let the drop tune footswitch turned on/off for the entire song, as it is placed higher on the pedal. 

Why it Stands Out to Us

The Whammy pedal is a legendary unit that allows excellent pitch shifting. It is a real asset to any guitarist’s pedalboard, and it includes true bypass, chordal whammy pitch shifting, and, of course, the classic and deeply loved Whammy sound. It is also highly versatile.

Who Will Use This Most

Whether you want highly emotional, ambient chordal bends or a raging scream of your tone, this pedal can do both and a lot more. Highly recommended for guitarists of all levels, this pedal is great for electric guitarists on stage, during rehearsals or recording in the studio. 

Bottom Line

Overall, the Whammy pedal allows you to create complex harmonies to all of your songs. The universe of possibilities is truly endless – this Whammy pedal is not only legendary but a true winner when it comes to harmonizer pedals. It is indeed one of the most fun pedals you can add to your pedal family!

  • Extremely user-friendly 
  • Excellent sound qualities and glitch-free
  • Can shift or harmonize your tunes by 3 octaves up or down or both 
  • Incredible abilities for pitch shifting, creating harmonies and octaves

CONS

  • Average response time – has a bit of latency compared to Whammy for instance

What Recent Buyers Report

The Pitch Fork is all about sound quality and top-notch performance. It is versatile, as you can tweak its controls to perfection to achieve a wide range of harmonies and shifting. The tonal purity and the tonal potential are what make this pedal the perfect choice. 

Why it Stands Out to Us

The Pitch Fork is a rock-solid pedal that can shift the tones of your guitar 3 octaves up, down or both. You have a toggle switch located in the center of the pedal for ease of use, and it has two modes – momentary or latch, perfect for experimenting with and creating outstanding tunes. 

Who Will Use This Most

This pedal is a great choice for beginners and professionals and all in between. It is a must-try due to its blend between versatility and simplicity, high-quality, and glitch-free performance. The controls will allow you to create perfect tones at home, during rehearsals, or in the studio. 

Bottom Line

The Electro-Harmonix Pitch Fork is an outstanding quality harmonizer pedal that screams quality, craftsmanship, and performance. It is incredibly versatile, yet simple to use with intuitive knobs and controls. You can choose anything from harp-like tones or a synth bass – what else can you wish for?

Electro-Harmonix Pitch Fork Guitar Pitch Effect Pedal

PROS

  • High-quality sounds
  • Extremely affordable pedal
  • Well-built and durable case
  • Highly versatile with numerous controls
  • Minimalistic design perfect for a crowded pedalboard

CONS

  • Small controls for dry/wet signal adjustments
  • Can get unstable when pressed due to design
  • Useful mostly for taking down the octave and detune settings

What Recent Buyers Report

This pedal does its job quite well – has high sound quality, performs well, and consistent. On the other hand, the design could be improved – the knobs for adjusting wet/dry signals are quite small and, paired with the large main knob, the pedal can get unstable when pressed on. 

Why it Stands Out to Us

This harmonizer pedal is accurate, highly sensitive, and performs flawlessly. It is made from durable metal, and it has three control knobs and one switch that are highly precise and has a quick response time. You can adjust the dry/wet signal, choose the pitch shift range, and many more. 

Who Will Use This Most

This product is great for beginners or anyone looking for a budget-friendly option. It offers all the basic controls for a harmonizer pedal and allows you to benefit from high-quality effects on a consistent basis. It is definitely a must-try for any musicians just starting this journey.  

Bottom Line

Overall, this harmonizer is a budget option that allows you a great deal of flexibility. Despite its design issues, the performance is top-notch, and it is highly recommended for this feature alone. It is definitely a must-try if you are looking for a great pedal at an affordable price range.

PROS

  • ​Highly versatile and affordable
  • Can create three-part harmonies
  • High-quality and glitch-free sounds
  • A unique S-bend and detune modes

What Recent Buyers Report

The pedal is masterfully designed, which is no surprise from a Boss pedal. It is accurate, durable, and can be used with no fear – it is highly likely this pedal will outlive you. The only flaw of this product is that the knobs are quite small, which makes it quite challenging to use, but they are easy to grip. 

Why it Stands Out to Us

The Boss PS-6 pedal provides outstanding harmonies and voicing due to the enhanced DPS. Its features include harmony, detune, S-bend, and pitch shifter. It is also polyphonic, making it easy to shift between chords. Additionally, you can create whammy bar up effects.

Who Will Use This Most

Highly versatile and outstanding quality, this pedal is whole-heartedly recommended to all guitarists. Regardless of your skill level, you will definitely find some intriguing features to boost your performance. It is sturdy, long-lasting, and typically flawless Boss quality. 

Bottom Line

Overall, beginner or not, you have definitely heard of Boss products. Simply because they set a new standard in terms of musical gear – and this pedal is no exception to their reputation. You should positively have a look at the PS-6 if you are into quality, durability, and versatility.
