A loop pedal, or looper pedal, is an electronic device that creates instant recordings of a musical performance and plays those recordings back in real-time.
Why do you need a looper pedal?
A looper can define your sound in live and recording settings. Depending on the type of pedal you get, you'll be able to add multiple looped phrases, time signature changes, stereo sound, built-in effects and rhythm tracks to your creative arsenal.
Where do I put my looper pedal?
Normally, you'll want the looper to be able to record and playback any of your sounds. Of course, this means you should place it at the very end of the chain so it can hear and record whatever pedal combinations you use.
