Benefitting from Joe Satriani's years of experience and built to his specifications, the VOX Big Bad Wah is a dual-mode pedal with switchable access to two wah modes and unique features for a wide range of wah sounds. Satriani contributed numerous ideas that were unheard of in existing wah pedals, endowing the Big Bad Wah with an unparalleled range of sounds from vintage to modern, as well as controls so users can create their own unique sounds.
