I was having a terrible hum from my Yamaha keyboard. Figured I'd try the lowest price model which was this one, if it didn't work I could send it back...This one is all I needed!

cheap device did the trick

I was looking for a hum eliminator to place in line between my Ibanez Tube Screamer and my Fender twin. When I plugged my pedals into a power strip I got the normal buzz that everyone talks about.

I got this, not really being a "Nady Fan" but because it was a cheap device that claimed to do the trick. When it came in I took it out of the box, turned it over and heard something inside move. I thought it got damaged when shipped. I went ahead and plugged it up - and amazingly the hum was completely gone. Note I said "completely" - no trace left at all. I still don't know what that "moving part" sound is inside but it works like a charm. Now when I load my pedal bag up, I would sooner leave one of my pedals behind before I left this item behind.
