Behringer HB01 Hellbabe Wah-Wah Pedal
The Behringer Hellbabe Wah-Wah Pedal is a full-featured wah with extras more expensive pedals don't have. It starts with optical control that has no moving parts. This greatly reduces wear and tear, and thus extends the life of the pedal. It goes on to add a Boost function that provides an overdriven signal boost so you can really "bring the funk." The Q control gives you precise control over the filter shape, yielding vocal-type effects.
