Thank you for viewing. COLORSOUND Wah+Fuzz Pedal Functionality confirmed, with box. Purchased new in 1997, with original warranty. There are scratches and paint chips, but it's relatively clean. As you can see in the first photo, the two switches on the left and right turn Wah and Fuzz on and off. Of course, they can be used simultaneously. The knobs on the side control the Fuzz GAIN and VOLUME. Brand: COLORSOUND - Model: Wah Fuzz Pedal - Color: Yellow
