Place the two Boss Loop Stations side by side on the floor.
Connect the two Boss Loop Stations with a short instrument cable. Plug one end of the cable into the input jack on the first Loop Station. Plug the opposite end of the cable into the output jack on the second Loop Station.
Attach an AC power adapter. Boss Loop Stations have two power options. One option is to use a 9 volt battery. The second option is to attach an AC adapter to the Loop Station and then connect it to a power source. The second option is the better choice. Weak batteries interfere with the quality of the Loop Station. Plug the AC adapter into the Loop Station.
Plug an instrument cable into the output jack of the first Loop Station. Plug the opposite end of the cable into the input jack of the guitar amplifier.
Plug a second instrument cable into the input jack on the second Loop Station. Plug the opposite end of the cable into the input jack on your guitar.
