Harmonizer pedals

Harmonizer pedals

Harmonizer pedals add one or more additional voices to your original signal. These voices are placed at a fixed interval, such as a third, fifth, or octave. This makes your sound fuller, more musical, and instantly more interesting. Harmonizers are widely used in rock, metal, ambient, film scores, and modern pop productions.

What does a harmonizer pedal do?

The pedal analyzes your tone and automatically adds a second or third voice. You play a single note, but you hear a complete harmony. Modern harmonizers follow scales, notes, and chords so the additional voices always fit musically. This allows you to create harmonies live and in the studio without having to play with multiple guitarists.

• Two-part harmonies with recognizable intervals.
• Polyphonic harmonies for a wide, choir-like sound.
• Scale-based harmonies that move with your melody.
• Creative effects like robot voices or synth-like layers.

Why harmonizer pedals are popular

• You instantly make solos bigger and more melodic.
• You supplement riffs with a second or third voice without an additional guitarist.
• You create modern ambient or synth-like soundscapes.
• You can make complex sounds with minimal playing input.

Types of harmonizer pedals

The options vary by pedal. The right choice depends on how much control you need and how complex your harmonies are.

• Fixed-interval harmonizers that always play the same interval, for example a fifth above your note.
• Scale-based harmonizers that automatically switch to a chosen key.
• Intelligent harmonizers that follow melodies and harmonize complex chords correctly.
• Multi-voice harmonizers that add two or three extra voices at once.

Choosing the right harmonizer pedal

When choosing, consider the pedal's tracking, tuning options, and musical flexibility.

• Choose a low-latency pedal for live use.
• See if the pedal can work polyphonically if you want to harmonize chords.
• Note the number of available intervals and voice combinations.
• Check if you can set scales and keys.
• Determine if you need additional features such as pitch shifting or detune.

Tips for better harmonizer results

• Set the harmonizer before your drive pedals for clear tracking.
• Play tight and clean to avoid misrecognition.
• Use subtle intervals for a natural-sounding second voice.
• Use multiple voices sparingly to avoid cluttering your sound.
• Combine with delay and reverb for a full, ambient sound.
