I literally don't hear any difference.

The other day, the pedal wasn't working right (muted sound while it was on) and so I brought it into the guitar store and they checked it out. It worked just fine for the guy at the guitar store. I heard the difference with it on their amp. He kept turning it off an on so I could really tell the difference the pedal was making on the amp's sound. It was wonderful!

But, I took it home and didn't hear it.

Now, I bought my amp from someone that had this pedal so I got to hear the difference his pedal made. That was why I purchased the pedal in the first place.

Any help is appreciated. Thanks!
