Add my voice to the many, fierce hiss makes it unusable. I bought it for using on the 2 channels of a powered board that didn't have pads on them. I thought if you were padding down a guitar that would give you less noise not more. But the more pad you use on the box, the louder the hiss. Damn, you'd think Behringer could at least make a direct box!. Those $7 XLR to 1/4 inline transformers work fine. Remember if it says "Professional" on the box...It's not.
