Modulation pedals are the paintbrushes of your tone palette. They take your core sound and add movement, texture, and dimension. From subtle shimmer to wild modulation, these effects transform static tones into living, breathing soundscapes.
What Is Modulation?
Modulation effects work by splitting your signal and manipulating one copy—typically by delaying it slightly and varying that delay over time. This creates the characteristic movement and texture.
The Main Categories
Chorus
Creates a thicker sound by combining your signal with a slightly detuned copy. Like multiple guitars playing together.
Flanger
Uses shorter delay times with feedback, creating that characteristic "whooshing"jet airplane sound.
Phaser
Uses all-pass filters to create notches in your frequency response that sweep up and down. Liquid, flowing texture.
Tremolo
Modulates the volume—your signal pulses between loud and quiet. From smooth sine waves to choppy square waves.
Vibrato
Adds pitch modulation to your signal. The note warbles up and down in pitch.
Key Features
- Rate: How fast the modulation cycles (LFO speed)
- Depth: How intense the modulation effect is
- Stereo: True stereo outputs for wider soundstage
