A multi-effects pedal is a versatile device used by musicians, particularly guitarists and bassists, that combines multiple effects and signal processing features into a single unit. It allows players to access a range of effects—such as reverb, delay, distortion, chorus, and more—without needing to use multiple separate pedals.

Multi-effects units typically offer a variety of preset and programmable options, enabling musicians to create and save complex effect combinations and signal chains tailored to their specific needs. These pedals often include features like digital amp modelling, built-in tuners, and other utilities, providing an all-in-one solution for both practice and performance.
