A distortion pedal is an electronic device used by guitarists to modify the sound of their instrument. It works by clipping the audio signal, which creates a "distorted" sound characterized by a gritty, aggressive tone. This effect is popular in various music genres, especially in rock and metal. Musicians can control the level of distortion, tone, and volume through the pedal's knobs. Distortion pedals can enhance a guitar's sustain and add harmonic overtones, making them essential for achieving specific sounds. Many famous guitarists, such as Jimi Hendrix and Kurt Cobain, have used distortion pedals to shape their signature tones.
