Chorus

Chorus is a modulation effect that thickens and widens a sound by duplicating the signal, slightly detuning it, and modulating its pitch over time. This creates the impression of multiple instruments playing together, resulting in a rich, shimmering, and spacious tone.

It is commonly used on guitar, bass, and keyboards to add movement and depth, working especially well with clean or lightly driven sounds. Chorus became strongly associated with 1980s music but remains widely used across pop, rock, ambient, and modern styles for its ability to make a sound feel fuller and more animated.

Flanger

Flanger is a modulation effect that creates a sweeping, jet-like sound by mixing the original signal with a slightly delayed copy that is continuously modulated. As the delay time changes, it produces a series of moving peaks and notches in the frequency response, giving the effect its distinctive whooshing character.

It is often used to add dramatic movement and texture to guitars, basses, and synthesizers, ranging from subtle shimmer to intense, psychedelic sweeps. Flanger is commonly associated with classic rock and experimental sounds, but it remains widely used wherever bold modulation and motion are wanted.
