This product works very well BUT, for Australian purchasers be aware that the power source is a 110/7.5V AC adapter and finding a 240/7.5V AC adaptor in Aust is all but impossible! I eventually found one in the UK! Good product but designed for the US market.

I used it for my Clavinet. Works great, although some times you can tell it affecting the tone ever so slightly. I say its worth a try if you are experiencing hum. For the price its a good way to go, even if just to try it out, and electro harmonix makes great stuff. So de-bug that hum de-buggy!

This thing actually works! I have two of them and I use them on my P bass, my Strat and Wurlitzer keyboard in my home studio. It's a necessity for any single coil pick up instrument, or any device plagued with AC hum/noise. It works on a whole different principal then most 60 cycle hum removers. On the strong setting it might suck out a little high end tone in some circumstances but I rarely notice much difference while playing and the benefits far outweigh that. The one _caution_ that you have to be aware of is that it uses a very specific non-standard power adapter that is crucial for tying it into your AC mains for it to "read" the hum and interference and remove it. If you see these for sale without the power adapter don't buy it. I've spoken to Electro Harmonix on a couple of occasions and although they were very responsive, believe it or not they were unable to sell me a separate power supply. (I think it's something like 17.5 V AC)Read full review

Like many guitarists who use single coils, I was having trouble with 60 cycle hum, and possibly other RF/EMI noise from the old wiring in my house. I tried a number of solutions, none of which really worked (the gate stopped the noise when I wasn't playing, but didn't help when I was playing). I read the reviews of this item and decided to take a shot, and I'm glad I did. On the normal setting, the Hum Debugger basically reduced the noise to a very tolerable level. It's not totally gone, but when you start playing it isn't noticeable anymore, which definitely wasn't the case before. The stronger setting gets rid of a bit more, but I don't detect a huge difference between the two settings in my rig. Best of all, I detect no change in the tone of my instrument, and I cannot hear any echo or "slap back" effect that some reviews have brought up. So this unit really did the trick for me, and now I can get rid of the gate. Obviously different rigs and different sources of noise may produce different results, but I recommend at least giving the Hum Debugger a shot if you're struggling with hum and noise.Read full review

Works great! Does what I wanted it to do which is cut out electronic hum without affecting the tone adversly. It works better on Normal than Strong for me. I find that Stron affects the tone too much although it also gets rid of the electron 60 cycle hum. I use it with various Fender Jazz basses I going to let a guitarist friend use it with his single coil Strat and see how it does but right now he's having too much fun with a Humbucker 335 to go back to the Strat just yet.
