100% analog Volume/Wah 2-in-1 pedal with a lightweight yet sturdy and well-constructed casing. Active volume control helps prevent impedance mismatch issues. Please use a TRS cable; otherwise, volume control may not be smooth. Provides a classic wah sound. Switch between volume and wah modes using the hidden footswitch. Two LED lights show the pedal's operating state, indicating which mode is active. (Power adapter not included)
