Rids your system of unwanted hum safely .

The Hum X Exterminator removes unwanted voltage and current in the ground line that cause ground loop hum. This noise reduction adapter simultaneously maintains a solid, safe ground. You no longer have to run your audio signal through filtering that results in loss of volume, tone, or both. Some devices simply remove or float the ground, which is never safe! Hum X removes the ground loop while leaving the ground and your signal intact. Easy to use and completely effective!


It's the safest way to get rid of ground loop hum. Order Hum X today!

    Let's face it. Power is unpredictable. From the outlets at your house, to the outlets at the gig, to the outlets in the studio (which SHOULD be protected and quiet...). The Ebtech Hum X Hum Exterminator should be permanently attached to the power cord of any musician that has gear that plugs into the wall.

    THE TEST:

    I have the luxury of having two identical little Crate V5 combo amps. I plugged them both into the same power outlet in my house (one in the top outlet, one in the bottom) and turned them on with the volume at about 3/4. They both exhibited the usual hiss/cyclical 60-HZ noise. Then I turned off the bottom amp, unplugged it, put the Ebtech Hum X in-line, plugged it back in, and turned it back on. No noise. I repeated this operation with the other amp just to make sure I wasn't crazy. No noise. I've lived with the fact that the power in my house is "less than desirable" when it comes to noise and amps/recording. I don't usually throw around the word "panacea" but this little plug is a must-have if you've got noise coming from ground loops or bad power. It's been a long time since a piece of gear impressed me as much as the Hum X. Now I'm just wondering how they do it in such a small package. I've had my original one for about four years now and it's solid as a rock!

    I got the hum X hoping to reduce or eliminate hum associated with having my amp (a Lunchbox zt 200 watt solid state) plugged into a a Goal Zero Yeti 150 combination battery/generator to play live where there is no power source. I'm an experienced player, but I have very limited knowledge of electronics. This product did nothing to reduce hum. I removed all effects, plugged the amp directly into the hum X and the hum X directly into the yeti 150 and then compared that with plugging the amp directly into the yeti 150. No noticeable difference. It's not the amp. I don't get the hum when the amp is plugged into a wall socket in my house, which is properly grounded. Apparently, the hum X was not designed to deal issues associated with battery powered generators.

      Comments about Ebtech Hum X Hum Exterminator:

      The sales staff at Musician's Friend is knowledgeable and helpful. They recommended that I try the HUM X to solve a buzz in my amplifier that is caused by overhead lighting. Unfortunately it didn't work and Musician's Friend was easy to work with when I returned it.

                  This product hasn't actually resolved any of the hum issues that I've come across... that doesn't necessarily mean it's not doing what it's supposed to, it just means the hum issues I've dealt with tend to run deeper than the ground.

                  I suspect this little guy would be beneficial for the live sound engineer or gigging musician to have in his/her toolbox. That said, it's fairly pricey for what it is, and hasn't proved itself useful in any studio setting for the passed year that I've owned it. My advice would be to be sure that your hum issue is solely ground related before purchasing this unit... otherwise it will likely serve as an expensive paperweight 99% of the time.

                      I've been using these for years and they have saved the day on multiple occasions. As in a lot of clubs, the power supply can be a little noisy and these little guys are just the thing to use to get rid on that pesky noise. I carry two of them with me on all audio gigs I do just in case. They may not clean up everything, but they do a darned good job of removing noise from amps and PA's on the majority of situations.

                              I bought this because of the positive reviews. It did not help me at all though, so I returned it. It couldn't hurt to try it to see if it helps solve your noisy power issues. YMMV.

                              FYI, it has a larger footprint than a regular transformer spot, so even if you have a transformer spot, it will still take up two outlets.

                                As soon as I isolated the problem (massive ground noise from an 2nd board I have coming into a sub on my main mixing board), I plugged the 2nd board's rack AC into the Hum X and into the wall - and Zap - like Magic - no hum at all! Awesome!

                                  I tried plugging in the Hum X Hum Exterminator
                                  every way I could think of but it made no difference at all. I have a pretty standard pedalboard (wah, distortion, delay/chorus, tuner) and it didn't take out the hum that I get from flourescent and neon lights. Even pulled everything off my board and started from scratch with this thing plugged in to each pedal...didn't help. (also tried different guitars)...I know the problem is on my end...just wanted folks to know that this thing won't perfom miracles for you...(oh and yes tried plugging everything into a power strip with the Hum X Hum Exterminator...no good)
