The best way to use a loop pedal will definitely depend on your purpose of buying it. For example, if you are considering it for studio use than I wouldn't really recommend one. It is pointless since in the studio you can record your backing tracks and then record solos or melodic parts and then put them together properly with nice editing, eliminating the need for a looper pedal. The best way to use a looper pedal is when performing live or when practicing in the house. Many street musicians rely on loopers to create different layers of music and deliver great performance. LIve musicians that perform on the stage can utilize them perfectly as well, recording the rhythmic parts first and then playing melodic parts and solos on top of them, which is awesome.
