Featuring an easy "Plug in and Play" design, the pedal boasts a virtually indestructible aluminum alloy casing, an anodized black pedal shell for protection against wear and tear, a super smooth Kevlar drive, a generous 12-degree foot sweep and a bright LED on-off display. Battery operated, the Ernie Ball Wah pedal is a must-have for any serious musician. Optional AC adaptor sold separately
