1 piece BOSS pedals are delivered ex works with a battery attached, so the available power may vary. With the pedal, the circuit is activated as soon as a 6.35mm (mono) jack cable is plugged into the output jack. Regardless of whether the pedal is activated (looping) or not, the battery discharges. The average life is about 2 hours. Don't leave the cable plugged in overnight Remove all batteries from the battery compartment, replace with a new, fresh (non-rechargeable) 9V battery, and then plug a mono or TS cable into the output socket. Both the power LED and the screen should then be activated. BOSS pedals also work with a 9-volt power supply. To check if the pedal is working, it should be tested with a battery first. Then removed the battery and an official BOSS Inserted the power supply and tested the pedal in the same way.
