What big orange beauty have we here? Well, this is a basically the classic Phase 90 pedal in the housing of the Cry Baby Wah. It's activated by the spring sensor, so as soon as you stomp on it the phasing kicks in and gets quicker as you press down further. It's a terrific effect; very musical and spacey and a lot of fun. Made in limited numbers.
