This is the Flanger side of this amazing pedal. I think I like the Flanger best of all, actually as it's super versatile and sounds great.
You'll find a Chorus-only demo of the Twister 2 also on this channel (See: http://www.youtube.com/watch?v=thq1K84YmGQ) There's another video to come: General demo with distortion. Soon..
Cheers,
