Fully depress the pedal to turn the effect on, and depress it again to turn the effect off. With an optional foot switch connected to the Remote On/Off Jack, the effect is switched with the foot switch instead.
It adjusts the peak level of the filter that creates the wah effect. Turning it counterclockwise gives a softer sound, while turning it clockwise gives a deeper wah effect.
It uses one 9-volt battery (006P/9V). The Check indicator also works as a battery check and becomes dim when the battery is depleted.
Use a BOSS PSA-120, 220 or 240 AC adaptor, chosen according to the voltage system in your country. Other types of adaptor may cause malfunctions.
