Many wah pedals only sound good when they're moving. The Ernie Ball Wah is designed to sound good regardless of where you have it set. Made from an aluminum alloy casting providing major durability, the wah pedal has a 12-degree foot sweep with a smooth coated Kevlar drive, true bypass, and adjustable on/off switch with a bright LED when on. It's AC or battery powered with easy battery access. A/C power jack and 1/4" instrument jacks are all on the back, keeping the Ernie Ball Wah's footprint small.
