A very good flanger that loves to live right on the border to chorus - so if what you are looking for is that sort of steely, icy cold modulation that sounds like chorus with anything lush taken out, this is the one. It does not get super jet-flangy sounds, but plenty heavy if you desire.
As is often the case with flangers, the controls have a fairly wide range, and mind-blowing sounds sit right next to horrid and fairly bland ones. It may take a moment to dial in. Also, the LED is tiny and dark. If this is set right, you will KNOW it is on, LED or not, but still - can be a bit annoying.
