My wife bought this for our karaoke machine. Not the Best Buy, but I was able to dial in the gate for vocals. I used it on my Stratocaster set up and it did kill a lot of hiss. Don’t get me wrong, even the pedal is set perfectly, you can still kind of tell there is a noise reduction pedal in the chain. But it does get rid of unwanted noise very well. Item is in mint condition, and comes with the D'Addario PW-CT-9V DC Power Adapter shown in pictures. The sale does not come with the white quarter inch guitar cable in the picture. Pedal is guaranteed to look and work as brand new.
