Yep, I have one. Its a pretty cool unit with some decent filters and effects. Great price for an effects unit too. I like mine. I haven't used any other fx unit, so I couldnt tell you about how it stacks up with the more expensive ones (such as the Pionner models).

nice...im interested in the interface is it very intuitive?

It is very easy to use. You just turn the dial to the number of the effect you want (a nice card comes with it with the number, and short description of each effect), press it to activate it, then move your hand over it to control how much or what the effect does. You can press the button again for it to hold that effect. Be careful though, a little hand movement goes a long way in changing the sound, especailly the Z axis (up and down). Just takes a little getting used to.
