This thing is terrific. I love the fact that it allows me to play my guitars without dragging a cable around, but my favorite thing about it is how it eliminates the hum that has plagued my guitar setup since I moved into my current house. Let me explain in detail in case anyone is having a similar issue in their house...Whenever I plugged any of my guitars into an amp or recording equipment that was plugged into any power outlet in my house, there was an annoying and steady hum that I could hear. I used a tuner app on my phone to verify that the hum was 60hz. My guitars with lower output pickups made the hum sound worse because the signal to noise ratio was lower. The only way to get the 60hz hum to go away was to plug my guitar into an amp that was battery powered. I tried a power conditioner to no avail, confirmed my guitar cables were shielded, and confirmed my guitars weren't defective. I asked the pro audio guy at Guitar Center, a luthier, a friend who is an electrical engineer, and even an electrician who was at our house, and they were all stumped at what could be done to solve the problem. I came to accept that something outside of our house (e.g., perhaps the high voltage power lines that are less than 200 yards away) were causing some time of ground loop or interference, and that certain guitars just couldn't be used in my house because of the annoying hum.Then one day I had the idea to try this. I thought: given the fact that plugging my guitar into a batter powered amp fixed the issue, perhaps breaking the physical electrical path between my guitar and wall socket via a wireless system would also work. And indeed it did! I can now use any of my guitars, even the ones with lower output pickups, with an amp or recording equipment plugged into my house wall sockets, and I'm hum free!
