In this article we’re going to be discussing the best vocal harmonizer pedals that exist in October 2023.
Whether you’re in the studio or you’re performing live, it’s hard to imagine proper vocal processing without a harmonizer effect. It is one of the most important tools for lead singers, which gives a completely new dimension to their voice. In the past, harmonizing was possible only with backup singers but today, things are much easier, as well as less expensive.
What Is A Vocal Harmonizer Pedal?
A vocal harmonizer pedal is a pedal with a harmonizer effect. It is a type of pitch shifter that changes and combines the effect tone with the original tone, making a two-note harmony. Modern devices are able to make more complex harmonies as well. Today’s pedals offer different types of harmony types, such as fixed, high or low, which can also change the octave. Of course, users are also able to select in which key they want to harmonize and completely change the character of their voice.
A harmonizer is an essential tool for vocal processing but in most cases, it doesn’t come as a single effect in a pedal housing. In most cases, manufacturers pack harmonizer together with other effects, making a multi-effect processor. Many of these devices offer numerous effects, as well as a preamp, as well as various connectivity features. In that way, musicians get a complete solution for their vocal shaping in a single housing, which is more practical and less expensive.
Therefore, please note that most pedals on the list are multi-effect units or complete vocal processors.
