A pedal, in the context of music, refers to a device that modifies the sound of an instrument, typically electric guitar or keyboards, by altering audio signals as they pass through it. Pedals can serve a variety of functions, including effects like distortion, reverb, delay, modulation, and compression. They are commonly used by musicians to enhance their sound, create unique audio textures, or achieve specific sonic qualities that would be difficult to produce with the instrument alone. Pedals are often housed in sturdy enclosures with footswitches that allow musicians to engage or disengage effects during performance easily.

Pedals can be analogue or digital, with each type offering different characteristics and qualities. Analog pedals, for example, often provide warm and rich tonalities due to their continuous signal processing, while digital pedals can emulate a wide range of effects and often include more advanced features, such as presets and programmable settings. Many musicians use multiple pedals in a “pedalboard” setup, connecting them in series to create complex soundscapes. With their versatility and ability to transform an instrument’s tone, pedals have become essential tools for performers and composers across various genres, from rock and jazz to electronic and ambient music.
