[en-ma]

A multi-effects processor is an electronic device that combines multiple effects, such as distortion, chorus, flanger, reverb, and delay, into a single unit. These processors allow musicians to apply multiple effects to their instrument’s sound at the same time, or to use different effects in different parts of a song. Some also include features like equalization, noise gate, and compression. They can be in the form of a pedal, a rackmount unit, or a software plug-in.
