Harmonizer Pedal? EVERYTHING You NEED to Know!

Did you know that the harmonizer effect can add depth to your mix? This is important to understand if you are looking to spice and create some amazing textures to your sound!

In this article, we look at the harmonizer pedal in detail… Lets get started!


The harmonizer pedal is a device that you plug into your signal chain and it duplicates the input signal creating harmony to your melodies.

The Harmoniser pedal can set the pitch playback, whereby it plays the new signal against the original input.

By playing the original pitch alongside the new pitch the two pitches blend into one creating a  perfect harmony.


This device delivers the output signal simultaneously, guaranteeing no mistakes or mismatches in time. 

Because of the two corresponding signals being alongside each other, this is known to thicken to guitar presence, generating a thicker tone and creating a very unique, new color to your music.


You should always keep in mind that the more you adjust and apply effects to the original sound, the more artificial it can become. It will eventually sound too unrealistic.


The harmonizer pedal works by mimicking the original input signal and playing it back (alongside the original signal) to a different pitch, which creates harmony.

With more advanced pedals, you can either lower or raise the pitch of the sound to any number of intervals, octave up and octave down. It will keep your original sound and combine all the melodies together creating any kind of harmony.

You will know that these are both used for removing the original sound and adjusting the pitch as desired with higher or lower notes. Now, the “harmonizer pedal” is considered to be a subtype of the pitch-shift pedal.

However, it is more advanced as the pedal recognized your pitch, so that you can make it playback perfect 3rd, 5ths, and more within your scale.


  • The harmony (also called Type) knob: Basically this is used for adjusting the type of voicing you want to apply to your sound and tone. The options are listed as following: high, higher, low, lower, octaves,…
  • The level knob (also displayed as Blend, Mix, or Balance): Have you ever wondered what is the amount of adjusted pitch-shifted tones after entering the harmonizer when placing in comparison to the level of volume of your original sound? How loud is it referring to the harmonized line? That’s what this knob’s function is.
  • The Tone knob: Adjusting the brightness of your original input sound. Basically controls the amount of treble in your mix.


Placing your pedal in the most suitable position in the whole signal chain is extremely crucial to the quality of the sounds generated as well as fitting in your flavors and interests. Different positions can generate different outcomes and may completely change your original sound in a way that you might not really prefer to.

This is the basic and most common order in guiding how to arrange your pedalboards with multiple effects: Dynamics, filters, pitch shifters, and volume pedals usually come first at the beginning of the chain. Next up is the overdrive or distortion pedals. Following that will be the time-based effects (delays, reverbs) which are nearly placed at the end parts of the signal chain.

With a harmonizer pedal, it belongs to the pitch shifter group. So that means it should be placed somewhere at the beginning of the signal chain. To be more specific, it is suggested to be placed after the compression for a more accurate note. Since the closer the harmonizer pedal is to the original sound – the input will have higher chances to generate cleaner outcomes after duplicating.

And the main reason why you should not put it after-effects like overdrives is that this can cause the input signal entering the harmonizer pedal to become too complex and mixed up. It is hard for the pedal itself to work on and transform that distorted overtones for stacking all the layers together.

Electro-Harmonix Pitch Fork is considered to be one of the most easier types of harmonizer pedals for any guitarist to practice.

The switch-mode in the middle allows you to set up the harmony to be below, above, or maybe at the same time. And most important is the Shift knob, which controls the available octaves to add into your original sound, maybe 1, 2, or even 3 depending on how you want it to be.
