The GOKKO Repeater is a looper has a 10 minute loop time and an unlimited amount over overdubs. When the pedal is plugged in and connected pressing the foots witch once to begins recording the loop (the LED should go red). Pressing again to replays the loop (the LED should be blue at this point). You can then press the foot switch again, onto red mode, to record another layer of the loop, and again into blue mode to mark the end of the loop. You can do this as many times as you want adding layers to the track. Holding the foot switch when blue LED is lit clears the previous recording.
