As the first bass player to ever record with a wah pedal, Black Sabbath's Geezer Butler is a true rock pioneer, and was the only logical choice when it came to Dunlop developing their very first signature Cry Baby Wah for bass.The Geezer Butler Cry Baby Bass Wah is identical to the one that he takes out on the road, and is specially designed to coplement Geezer's massive low end power with a midrange that cuts through the mix. Dunlop took the aggressive Cry Baby 95Q Wah and modified its sweep to Geezer’s specs. With your heel down, custom circuitry mixes in just the right amount of dry signal. Rolling forward towards the toe-down position smoothly removes your dry signal and lets the aggressive part of the wah range come through. Convenient auto-return switching lets you step easily in and out of the effect, and you can adjust the shape of the frequency’s bandpass, using the internal Q control which comes factory set to Geezer's preference.
