I really love this pedal. first of all its really well mad, strong enough to stand gigging.
Then the sounds, which go from a mild Chorus/ Flange effect to an absolutely bonkers head in a bucket mash of swirl and swoosh. The rate can be adjusted for the speed you want or you can take it down to what EHX call the filter matrix which can give an almost autowah effect amongst others.
The stereo output is brilliant for plugging into another amp should you wish, this also works even when the unit is switched off.
This pedal would enhance most tones from clean to dirty.
By the way you need to use the 9v power supply provided with the pedal, I tried it with my pedal board supply and it just developed a really annoying bass hum.,
My only gripe is it would be good to be able to switch Flange and Chorus separately, but hay I still love it.
