With the Mooer Free Step, the specialists for compact guitar effects combine the Wah and volume pedals in one housing. A slide switch on the side can be used to select whether the wah-wah effect, the volume control or both are active together. Also accessible on the side of the pedal are a Q control, which determines the filter bandwidth of the wah effect, and a control for setting the minimum volume level in volume mode. The Mooer Free Step can be activated either classically via a switch under the pedal or in sensor mode, which switches on the effect when the foot is put on.
