Removes Hum, Preserves Tone

Hum is an unwelcome distraction. That’s exactly why Morley created the Hum Exterminator. It makes short work of the unwanted voltage and current in the ground line, which can cause ground-loop hum. What’s more, it gives you a solid, safe ground, unlike those often-dangerous devices that remove the ground altogether. At Sweetwater, we appreciate devices like the Hum Exterminator. These handy tools enable us to eschew volume- and tone-sucking filters and ground lift adapters. The Hum Exterminator is a breeze to use, a cinch to install, and it sounds great! Morley’s Hum Exterminator can be used with any device with a 3-prong outlet that doesn't draw more than 6A of power.

Morley Hum Exterminator Features:

  • Removes unwanted voltage and current in the ground line to eliminate ground-loop hum
  • Gives you a solid, safe ground, unlike devices that remove the ground altogether
  • Enables you to eschew volume- and tone-sucking filters and ground lift adapters
  • A breeze to use and install
  • Works with any device with a 3-prong outlet that doesn't draw more than 6A of power

It works!

I tried just about everything to solve a ground hum in my subwoofer. First I purchased some power conditioners to see if that would help. It didn't stop the hum, but at least it made my system safer.

I finally narrowed down the source of the hum. It was the power supply for my second monitor. I did some research and found the Morely Hum Exterminator. I wasn't sure if it would work, considering I had tried all kinds of other things that failed to stop the hum. The Morley arrived and I plugged my second monitor into it and plugged it into my power conditioner. The hum stopped. Completely gone.

I am so happy with this purchase and can highly recommend this to anybody with stubborn ground hum in their system.

must have

If you are using a tube amp and are planning on playing anywhere other than your bedroom, get this. Most local venues are wired by people who don't know what is needed for a band; therefore, you can get some shoddy wiring and hums. This has worked so far at knocking that our and cleaning up my sound.

No Hummus Among Us ;-)

I've had a pair of Passive Avantone Mix Cubes (purchased at Sweetwater, of course) running through a 1990's Alesis RA-100 power amp that have always had noticeable hummm when sitting idle. After trying different power sources and different cables, I purchased the HumX, installed it and problem solved! As always, a dual thumbs-up for my Rep, Adam Chesi.

Morley Hum Eliminator

I was ready to trash a headphone distribution unit due to loud 60 cycle hum but decided to try this Hum Eliminator first. Pugging it into the headphone distribution device's A/C power cord silenced the hum nearly completely allowing me to continue to use it. I also use one to reduce Hum in a set of monitor speakers at a live show venue with similar successful results.
