The RevoL effects AUTO WAH EWA-01 is an auto-wah effects pedal that automatically applies a wah effect in response to the strength of your picking. Unlike a regular wah pedal, which is operated with your foot, this pedal adds a "wah pedal-like effect" using an internal filter that responds to the intensity of the input sound. The item includes the main unit, box, drawstring bag, instruction manual, and other items shown in the photos. Since it hasn't been used much, the main unit is in good condition. (The box has some damage.) Please refer to the photos to make your own judgment, as criteria may vary. I believe the functionality is not an issue. It has been stored in a smoke-free and pet-free environment. Below is information about the pedal from the web: Main Features Effect/Sound • Picking Sensitivity Filter: The wah sound changes automatically depending on the strength of the strings. • Easy to create rhythmic wah effects and subtle nuances. Tone Variations • Selectable UP / DOWN wah operation: • UP → Simulates the "opening" direction of a wah pedal • DOWN → Simulates the "closing" direction of a wah pedal • Each reproduces the degree of pedal depression based on the intensity of the sound. Usability • Produces a natural wah effect in response to picking. Thank you for viewing. Best regards. Type...Electric Guitar Manufacturer...Revol effects
