A loop pedal is a device used by musicians to record and play back audio in real-time. It allows performers to layer sounds by recording a musical phrase and then playing it back in a loop. This enables solo artists to create complex arrangements without the need for additional musicians. Loop pedals are popular among various genres, including rock, pop, and electronic music. They can be used with different instruments, such as guitars, keyboards, and even vocals. Many musicians use loop pedals for live performances, allowing them to build dynamic soundscapes on stage.
