multi-effects

Multi-effects refers to a pedal or unit that combines several effects in one enclosure, such as the Vox StompLab series of multi-effects pedals for guitar and bass¹². Such units can process multiple effect types in sequence, as in the Electro-Harmonix Epitome, a digital multi-effect that chains polyphonic pitch tracking, flanging and chorus, and reverb³, or the EMS Synthi Hi-Fli, an early multi-effect unit combining fuzz, octave shift, ring modulation, phasing, and resonant filters⁴. Designs range from all-in-one offerings like the Mooer Red Truck⁵ to compact units such as the Valeton GP-5, which packs a flagship processor's features into a palm-sized enclosure⁶. The term is also used more loosely, as when Catalinbread describes its Bitters as "a multi-effects pedal on steroids"⁷.
