A looper pedal records and plays back audio in real time, allowing musicians to layer multiple parts and create complex soundscapes on the fly. Used by guitarists, bassists, and vocalists, loopers are powerful tools for live performances, songwriting, and practice, enabling a single musician to build entire arrangements by overdubbing different loops.

Looper pedals range from simple single-button units, like the TC Electronic Ditto Looper, to advanced multi-track loop stations, such as the Boss RC-600, which offer multiple layers, effects, and tempo syncing. Many loopers also include undo/redo functions, reverse playback, and built-in drum patterns, making them an essential creative tool for musicians who want to experiment with sound and composition.
