The only sound I hear now is the music coming from my bass guitar, no more hum, buzz or noise.

Small, fits into an outlet, red indicator light.

No learning curve just plug in and get great sounds from your instrument.

Seems to be made well, we'll see how long it lasts.

It is pricey, I shopped around and zZounds beat the price, it's cheaper than a noise gate which might not have solved my problem anyways, so I think it's worth it even at full price.

No, have no dealt with them.

Not much appeal, just something you plug into the outlet, maybe along the same lines as a night light that doesn't light up!

Playing guitar for almost a year, playing bass for about 6 months, just play at home for now.

A little bit of everything, going through the Hal Leonard method books for guitar and bass.

Just plugged it in, hum was instantly gone.

All you have to do is plug it in.

Again, just plug it in.

Best $70 i spent in a while.

the humx has killed every ground hum i've thrown at it, and my little apartment/bedroom studio is the lousiest-wired place i've ever called home.

so far, so solid,

yes, it may seem expensive for what it looks like, but i don't have the option of hiring a competent electrician to wire my apartment properly. i've bought three of these, and they're worth every penny. it's hard to put a dollar amount on clean sound.

it's simple, practical and works flawlessly. if you need it, you should have it, period.

Audio signal doesn't pass through it, so it has no effect except to reduce hum or buzz.

Its main "feature" is that it is NOT approved for safety by ANY testing agency, such as Underwriter's Lab (UL) and never will because it is EXTREMELY UNSAFE. The tiny diodes inside would never pass over 100 amps of current that would result if a defect actually occured in your equipment ... when you need the safety ground to prevent killing someone. Yes, I'm an expert on the subject and a member of UL's advisory panel on professional audio-video equipment!

Way too easy for some fool to kill himself with this product!

It's potted to prevent most folks from finding out what's actually inside ... 25-cents worth of components. IT'S A DEADLY ACCIDENT WAITING TO HAPPEN!!

What you get is a "half-baked" concept ... have these folks ever heard of Code or UL or safety? Do they care? I think not.

Support? No - marketing hype instead.

For those who know as little about safety as the manufacturer, this device is very appealing - and their techno-babble makes it sound like a great idea, but it's pure bull!

I have a horrendous hum or buzz in my Strat/Fender Blues Jr. system at home. It disapppears (except for the normal single coil noise) elsewhere. I bought the HumX in the hope that it would solve the problem. It did absolutely nothing. I recognize that I appear tohave a problem with the home wiring. I hired an lelectrictrician to test all the outlets and drive a new 10' copper gound- stil have the buzz that only goes away when I ground all the strings with my hand. The Ebtech website is not particularly helpful. I sent a polite e-mail to Ebtech askng for some guidance- gfot no answer.

Pretty simple. Plug in to outlet; plug amp into the HumX. The problem is that it did nothing to correct the problem.

For me it was a complete wast of money with no support form Ebtech.

I had a terrible hum/noise coming from my laptop when dj'ing. Made my Dell computer unusable. The Humx COMPLETELY got rid of the noise. Laptop is dead quiet now!

All you need is this little piece.

Plug it in, need more be said?

Seems like it is sturdy...only used it several times.

Gettihg rid of unwanted noise is priceless......or in this case...$69.95. Well worth it.

haven't needed support.

It's a plug adapter......don't want to marry it....but it's usefulness makes me still rate it a 10.

Sound Engineer/DJ

Whatever the band that hired me is playing. Typical wedding DJ.

I bought two of these to solve a hum problem (Motif XS to Yamaha HS-80M speakers) and a horrible hum, whirring, crackling, popping noise problem (Toshiba Qosmio laptop to Yamaha HS-80M speakers via the Motif XS). Note the common element - the Motif XS which does not provide balanced line outputs. The Qosmio laptop is a power hog and has a three prong AC plug for its 5 lb power brick. Ground loop ran from the laptop through the firewire cable to the XS, then on to the HS-80M, and back through the ground connections (consequently it would go away if I could have unplugged the laptop from its power source, but the laptop only runs about 45 minutes on its built-in battery). I plugged the Motif into a HumX and this eliminated the problem between the Motif and the HS-80, but there remained a path from the laptop to the HS-80 through the Motif - that is why I needed to plug the laptop into one as well. There was no effect on the sound (in this approach the devices are not in any legitimate signal path).

Plug this into your surge suppressor and the device into this.

This is a simple molded unit with a red LED that lights when power is present.

It solved a serious sound quality problem with an expensive synthesizer for a very modest price.

It's a power adapter - out of sight.
