The Ebtech Hum X does just what its supposed to do - cancels out the (almost always) Laptop AC Ground Loop Hum! Anytime you have a Laptop Computer within your loop/chain/board configuration, you can (almost) always count on having an "AC Hum" which is (almost) ALWAYS caused by the Laptop's external AC direct-connect Power Source/Transformer. Its easy to find out if thats your problem. Simply remove the Laptops external power cable, run the Laptop on its battery power source and "listen" for the hum to go away!!! If it does, then you know you definitely have an AC Ground Loop problem with the external power source.! Simply plug the Ebtec Hum X into your UPS/Regulated Power supply Output jack and then plug the Laptop's external AC cable into the Ebtec Hum X done deal! When ordering up the Ebtec Hum X, dont forget that there could be "other additional power-hum problems that need addressed. If thats the case and you still have other hums, checkout the other tips I have listed elsewhere in this review. Remember, very rarely does one piece of equipment handle everything. Note: DJ's have had this same (Laptop in configuration) problem for years and are amazed how such a simple plug-in device like the Ebtech Hum X eliminates the situation Since Ground Loop Hums seem to always be a problem, one piece of equipment normally does not handle them all. You need to isolate, in your configuration, just what piece of gear/cable is creating the "hum." The first place I would start (and install/place hum unit) would be at the Amplifier using a Dual-Channel type Hum unit (Nady HE1 or Ebtec). Connect the individual Output cables from your Pedal Board/Mixer and Guitar to the Input side of the (Nady HE1 or Ebtech Hum Eliminator) unit; Connect the Output of the (Nady HE1 or Ebtec ) to the Amps Input channels. Note: Make sure you use superior quality grade TS patch/jumper cables for connecting here (Hosa or DiMarzio are great.) Also, don't forget to check your Mixer XLR/Jack connectors for any added "hums" that maybe present. If this is the case, another solution is using the Ebtech HE-2R. This unit will handle 2 channels each of both your TS & XLR cable runs. Dont forget to inquire with your sales rep about purchasing/including within your configuration a good Regulated Power source commensurate with the equipment/pedals you are using in your overall configuration. They are a definite safety net and, will add years to your equipment by providing good, constant, clean power to your systems configuration. All of these mentioned units are of great value to your configuration considering they all do just what they are suppose to do. Yes, they are going to cost you a little extra cash however; sometimes these extra expenses are necessary in order to fix the problems. Pricey? Not really considering what you'll receive in the end - "Better Quality Sound" and isn't that what its all about??? As we all know: "if ya' wanna' dance, ya' gotta' pay the band." Good Luck!

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)

NOISE ELIMINATOR

By Scooterflash

from Florida

See all my reviews

Comments about Ebtech Hum X Hum Exterminator:

To the previous reviewer who ran his guitar or amp signals through this device. The device should be plugged into the outlet where you get the power for your all your gear. It's at the beginning of the power circuit that the noise reduction from the original power signal is recuced. I use it correctly and have found it eliminates at least 90 - 95% of ground loop noise. Once again the signal path is wall outlet to HUM X Exterminator to a multi plug circuit protector with an overload switch. Then plug in your amp and pedals and whatever else into the multi plug in device. This is a really inexpensive way to eliminate ground loop noise from your equipment without spending $1500.00 on a power conditioner.

Breaks ground loops, stops hum

By Jimmypagejunior

Ask me a question

Comments about Ebtech Hum X Hum Exterminator:

Other people on here who say this doesn't work have hum within their setup that has nothing to do with what this device is for. This will break the loop, eliminate hum, and help cancel noise from the outlet is is plugged into. It's simple, and it works as designed- perfectly. If you still have hum, troubleshoot your setup, but this will always do its job where you put it. I've have mine for 3 years, punishing treatment, and NO PROBLEMS WHATSOEVER. Some line noise that is not from the ground loops cannot be eliminated without spending gobs of money on special power conditioners or rewiring a bad circuit in a building. This thing works great for me, and even at least helps in those ratholes with really noisy power. Required gear for musicians. Example: last night, a new band I just started playing with, the guy doing sound flipped on his PA and got a loud hum. Obvious ground loop. I handed him my ebtech and told him to plug it in on one end. Did that, turned it back on, and the hum was GONE. He is now a convert and will buy several of these. BUY IT!

      Comments about Ebtech Hum X Hum Exterminator:

      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.

      Comments about Ebtech Hum X Hum Exterminator:

      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!

          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 bought a Morley ABC pedal so could choose between my 3 amps without unplugging my guitar every time. I have a tube and with about seven effects looped thought it and two solid state amps. They each have their own character and the Morley also gives me the option to play through all 3 with no power or tone loss. The only problem was once all that gear was combined I got a wicked ground loop hum. I tried plugging different things into different wall sockets. I even tried running extensions into other rooms to make sure I was on a different circuit. I looked everywhere online for a solution and I didn't want to spend hundreds on a solution. The Hum X kept popping up and I figured, why not? The first thing I tried was using it on my tube amp and Presto! Um was gone! By the way, Musician's Friend had the best price by far.

            I don't always eliminate hum... but when I do, I use HUM-X. LOL Seriously, this jewel has saved me several times dealing with the typically horrible power provided in small live music venues. It won't solve everything but it seems to fix typical grounding issues with amps, mixers, and effect chains. I keep one on my stage gear and an extra one with me on gigs. You never know when you will suddenly need another or someone else will need one.

              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.

                Comments about Ebtech Hum X Hum Exterminator:

                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.

                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'm a drummer who uses a laptop running VST's when playing live. The power supply from my laptop is very noisy 95% of the time. This little gem does what it says. I've tried in-line ground loop isolators that reduce sound level and quality simply too much for me to accept. The Hum X creates the silence and doesn't affect the sound quality. It seems pricey for the physical size of what you get, but it absolutely works for me.

Problem is that your tone changes with the iso-trans. I plugged my power strip into the HumX that carries my keyboards and effect processing on it. For once I had clean audio without lifting the ground and doing a 60hz dip in my audio recordings. I'm goint to spread the word on this device as I work in a broadcast facility and often have hum during our news live shots.

                I've been having a terrible issue with audible ground loop whenever I plugged in my Motif ES6, and couldn't record because the ground loop was so loud. The monster power center was no help, so after breaking my head buying tons of useless products, the Hum-X (As simple and cheap as it is) took care of the ground loop 100%. I'm extremelly satisfied with it - it does what it is supposed to. So if you're having a ground issue, there's your solution, don't even think twice..
