Summary: I have an MXR Phase 90, but honestly, I like this pedal almost as much. The main problem I have with it is the switch is odd; it doesn't actually click on and off distinctly. The input and output jacks are plastic, and not metal as on the Phase 90. Other than this, the construction is solid.
Summary: A pretty good phaser with substancial detail. I like the on/off switch, nice and smooth. The true bypass is a good feature albeit uses up some volume. For the price it is a satisfactory pedal.
Summary: Sound just like a MXR Phase 90. Does not have a nice foot switch as you can't feel the switch engage (no click) you have to watch for the LED to come on or listen. Physically Not as strong as a MXR Phase90 (Don't buy this to gig with) but great for home studio use.
Summary: It does the job though. I wasn't impressed by the lack of range, but then again I've never found a use for the more extreme settings on a phaser anyways. It seems that this unit keeps the effect within a safe and comfortable range and that's okay with me.
Summary: I was actually surprised when I got this that it wasn't plastic like the other Behringer pedals I have purchased. This one is cast aluminum I think. It definitely has the classic analog stomp box feel.
Summary: I bought this for a subtle phaser effect for a passive bass. That it does very well. If you're looking for a large degree of effect or lots of variety, look elsewhere. But, if you're looking for a very quiet "conservative" phaser I would highly recommend the Behringer PH9.
