Feature:
Behringer is trying to give us the extra option to introduce more or less modulation to give more of a chorus sound, but the "RISE" control didn't seem to do much. And it really sounded terrible no matter how I set the controls. I wouldn't clasify the sound as vibrato nor chorus. Just a trashy cheap sound.

Quality:
It was defective. There was an audible electronic clicking no matter if the pedal was active or inactive.

Value:
No matter what the price, it has to work!

Sound:
Terrible. The thing sounds more like a BAD chorus pedal. I bought it for the "classic" vibrato effect. It is nothing like the classic 60's, 70's vibrato effects. The "RISE" control doesn't seem to do much. And of course for ture "classic" vibrato, you wouldn't want any modulation. So that is a real problem.

Ease of Use:
They tried.

Support:
Don't know

Overall:
I wouldn't even use this if I were at the gig and had nothing else to use. I would just set it aside and play the guitar flat! That's how bad it is.
