Which modulation effect is NOT produced by the S6000?

The S6000 is renowned for its wide range of modulation effects, including chorus, flanger, and phaser. These effects alter the sound by combining it with delayed signals to create rich, swirling textures and a sense of movement. Each of these modulation effects applies different techniques: chorus simulates multiple instruments playing in unison, flanger creates a sweeping, jet-like sound, and phaser shifts the phase of the audio signal to create a characteristic whooshing effect.

Reverb, on the other hand, is primarily used to simulate the acoustics of physical spaces, creating a sense of depth and ambiance rather than modulation. While it can affect the perceived spatial quality of sound, reverb is not classified as a modulation effect like the others; it relies on different processing techniques to mimic the natural reflections of sound. Therefore, the correct answer highlights that reverb does not fall under the category of modulation effects produced by the S6000.
