Multi-effects pedals are versatile units that combine multiple effects into a single device, offering musicians the convenience of a wide range of sounds without the need for multiple individual pedals. These units typically include a combination of overdrive, delay, reverb, modulation, and more, with the ability to customise settings, switch between presets, and often store configurations for future use.

Popular multi-effects units like the Line 6 Helix, Boss GT-1000, and Fractal Audio Axe-Fx are designed to replicate the sounds of a wide variety of pedals and amplifiers, making them ideal for guitarists and bassists who need flexibility, especially in live performances or for recording. Multi-effects systems often feature amp modelling and preset banks, allowing players to access an extensive array of tones and effects, all controlled through a single interface, thus streamlining setups and enhancing performance efficiency.
