Lets start this piece off by telling you what exactly a 'loop pedal' is…
"A loop pedal is an effects pedal, usually for guitar, that can record a section of sound played on the instrument. It then plays back that section over and over, or for a set amount of repetitions. These can be useful when there is only one guitar player in a band that wants to play rhythm and lead guitar."
This thing gives me a MUSICAL BONER!
