A wah pedal made to last! The Behringer Hellbabe HB01 wah pedal boasts total optical control which means there are no mechanical pots and switches to wear out - a big bonus as far as gigging guitarists at GearNuts are concerned. You've got impressive control over your wah tone with an adjustable Range control and an additional fine-tune control. You can even choose between spring-back pedal operation or standard wah pedal operation.
