how to use a looper | Boss RC-3 Loop Station

In this video, we talk about the Boss Loop Station RC-3.
A Loop Station can record whatever you are playing and then replays it so you can play along to it.
I'm using :
Behringer V-Tone gmx 1200h amplifier
Harley Benton 1x12 Cab with Celstion V30
ESP LTD EX-50 explorer with EMG pickups (James Hetfield signature)
Epiphone acoustic guitar
Alesis drum machine.
