While looping has been instrumental in a successful musical career for Ed Sheeran and many others, a looper isn’t exactly an essential pedal for every guitar player.

It can, however, be a pretty useful one: a looper is a great home practice and ideas-generating songwriting aid, and can also be used as a creative substitute for a band behind a solo act’s live performance. Having a looper almost seems de rigueur for the modern busker.
