This pedal is as simple as a pedal should be. All it needs is one 9 volt battery or a standard AC adaptor (not included). Then you just plug your guitar lead into the side that says 'Guitar In' and it turns on. it's Status is represented by a red LED light. It's like any wah-wah, pedal down for treble and pedal up for bass, and then you just rock it back and forth to get that 'wah' sound.
