Thank you, and congratulations on your choice of the BOSS AB-2 2-Way Selector.

Connecting as shown here allows you to mute the sound from the
guitar amp when tuning the instrument.
Notes
• Do not use for switching power amp speaker outs and other
such powerful signals, as this may damage the unit.
• To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume on all devices, and turn
off the power on all devices before making any connections.
Operation
Depress the switch to toggle between Channel A and Channel B.
You can confirm the currently selected channel by checking to see
whether Indicator A (red) or B (yellow) is lit.

* The IN/OUT jack doubles as the power switch. Unplug the cable from
the jack after use to extend battery life.
Changing the Batteries
When an indicator (A or B) loses its brightness, it means that the
batteries are nearly dead. Remove the (two) screws from the
underside and open the cover. Then, replace the batteries (size
AAA) with two fresh batteries. Do not mix fresh batteries with
used ones.
