I hadn't had a chance to use this box until recently. The power in the venue I was in has always been problematic at best with light dimmers and motors in the ceiling for special effect lighting. My guitar processor seems to be sensitive to it and was horribly buzzing to the point where I couldn't use it. I had to use the sampled sounds on my Roland GR-55 for guitar sounds. During our break I remembered I had packed it and figured, what the hell. The damn thing worked! The buzzing which by the way wasn't the standard 60 cycle hum was diminished to the point that I could again use my whole rig. I used it again a day later at a rehearsal with a different band. There was a weird static in the lines and this time my vocal harmonizer was affected. I plugged in the box right after the harmonizer and it worked again. Apparently it will stop other kinds of noise and I'm sure it has it's limits so I've bought a power conditioner and between the 2 of them my rig should be silent again. I highly recommend the hum eliminator.

Audio Recording: if this doesn't solve your issue, then you have more than just ground loops affecting your sound. The only way to remove the annoying noises is to find what's causing them. This will help drastically.Ground loops fixed- my computer and audio interfaces are plugged into the same outlet, creating a loud griundloop when I plug the 3.5mm output of the computer into my mixer. As well as that, I connect an audio interface to my mixer by outputting the sound through 1/4" cables. The mixer. Hum and noise was overpoweringly loud. The Ebtech him eliminator removed the noise from being created from ground loops.Additional ground loop noise: I had remaining noise caused by my mixer feeding the final mix of sound into the computer (another ground loop between my PC and mixer. I had to find a noise reduction tool to eliminate the USB ground loop. I found a noise isolator from Intona (sold on Amazon). It's pricey, but is meant for hi speed transfer, which is audio recording.Quality of sound: other than noise reduction, I found no impact to audio quality. This box is passive, does not draw power, and fits in between your source and its destination along the line of cables.Identify what's causing the noise, attempt a solution, save your box, and return if necessary. But remember, there could be multiple issues with your system. This might only fix 1 of the few issues you're having.Recommend: I was highly skeptical. After testing and identifying my remaining causes of noise, I bought a second unitp.

This product works. It does kill some of the hum. The only problem is this company who is selling them keeps sending me "refurbished" ones when they are supposed to be new. The first unit I received only one channel worked, the other had a short in it. The second unit they sent me was dead.So what I suggest to everyone is go buy it at your local store. Have them order it if need be. Don't by it from this seller on Amazon. Once my busy touring schedule is over, I'll be returning both units for a refund. It's unfair to be expecting a new unit, and getting a refurbished broke unit instead.

I had hum problems due to a ground loop and older house wiring. I used channel one of the HE at the output of my effects loop and then ran the cable as normal to the effects return jack on my amp. Dead silent. No hum and no discernible degradation of the tone.Remember, (and this is very important) this unit is designed to eliminate ground loops between powered equipment. It is *not* designed to plug an instrument directly into it. It is an isolation transformer and it will impact your tone if you plug your guitar straight into it. Use it after any buffered pedal or device and it will do the job and work correctly. Plug a guitar directly into it and you will not like the result.

I tried this unit with my main guitar pedalboard for my electric rig. It made the ground loop hum worse.

Not exactly what I expected, but it did reduce some of the noise in my chain.

Overall I am happy with this product. However, I noticed that when using this isolation transformer after the pedals in my effects loop it causes a ~10db volume boost (but it did get rid of 100% of the hum). This is undesirable obviously, but I was able to work around this issue by putting the transformer in the loop before the pedals, however there is a slight but noticeable hum remaining when I place the transformer there. It's maybe 5% of what it was without the transformer. It's completely acceptable to me, but it might not be to others.

This is exactly what I needed for my fx loop setup. If the onboard reverb was before the loop then my amp would be dead silent. Don't take that wrong, this is NOT a noise gate. I had a particular issue where all of my pedals are located on a pedaltrain, all powered by one circuit. Two of those pedals are used through the fx loop. Without this hum eliminator, I had exactly that... Hum! Terrible hum.Hum is now gone. Buy this if you have a similar problem. A very affordable solution for a big problem.

I record telephone interviews using an Internet-based VOIP (voice over IP) telephone service, with the audio routed through audio mixers using balanced audio cables and output to digital recorders. The recorded interview audio suffered considerable "line hum" that I presumed originating somewhere in the analog audio setup. I installed Ebtech Hum Eliminator, but it turned out that the "hum" was originated from a noisy DSL Internet connection, *not* the analog audio setup. Despite this, I decided to keep the Ebtech box because it is invaluable when performing "process of elimination" diagnostics of analog noise issues that crop up occasionally. If you plug in the Hum Eliminator and the hum remains, then the problem is somewhere else or something else. Highly recommended.

Je suis vraiment déçu de cet Hum eliminator , qui pour ma part crée encore plus de problème qu'il est censé en supprimer

I was having ground loop issues using two guitar amps and an ISP Decimator G String which was the bridge between them and caused awful humming/squealing. The HE-2 cleared it up once I had set it up in the right order took some experimenting but once set up correctly it worked like a charm with no loss of tone and more importantly no humming!

ça marche mais ..... on à une perte en dynamique au niveau des aigus .... en live sa s’entend pas trop mais en home studio c'est flagrant ....donc a voir plus pour une utilisation Live qu'autre chose ...
