Finally!

After decades of research, trials, errors, marketing hype and outright advertising lies, I have found the answer to 60-cycle hum. This isolation transformer works perfectly.

As a professional guitarist, I have LONG known the grief and hassle caused by bad wiring in nightclubs, studios and my homes. I have tried EVERY CONCEIVABLE method for reducing hum and noise from my equipment: shielding, "noiseless" pickups, expensive amps, mixers, power-conditioners and egregiously-overpriced cables. NONE of those things worked.

Luckily, My wife is an electronic engineer. She suggested that the little "hum-x" I got from Ebtech was simply too small to do any meaningful isolation. I looked high and low, then found this Trip-Lite brand here on Amazon. The price was right so I ordered it, knowing Amazon's return policy is fair in case it didn't work.

It arrived today. I plugged in it to the wall, then plugged my noisiest, cheapest guitar amp into the back of the transformer.

At first, I though I must have hooked it up wrong, because there was absolutely ZERO hum. I checked the cables. Nope. Everything was right. I plugged in a guitar. Nothing. No noise. No hum.

Then I turned the guitar up full. Still no noise. When I strummed a chord, it startled the daylights out of me. The guitar was up full, the amp was up full. Still ABSOLUTELY ZERO HUM.

I have been searching for an answer to this pernicious ubiquitous problem for over 40 years.
This thing is worth it's weight in gold to me now. I lost two expensive pieces of gear just last month: one Kurzweil keyboard and a Mackie mixer, when the poor wiring in a local nightclub fried them.

This may turn out to be the best insurance policy on delicate equipment I have ever gotten. It certainly is the answer to my 60-cycle hum. The power here in my basement is the absolute worst, so it makes a fabulous proving ground ( get it? proving "ground") for this device.

THANK YOU TRIP-LITE!

If you have ANY sensitive electronic equipment, especially digital audio stuff, INVEST in one of these things.
Unlike all the Monster cable BS, Hum-eliminators, conditioners etc.
THIS THING REALLY WORKS!

Great if you want to eliminate a nasty ground loop (60 Hz buzz in your audio system) or isolate some test equipment. Appears to be well made. It is very heavy -- so buying online I'm sure includes the high cost of shipping (either directly or indirectly in the price). Price-wise it may be better if you cand find it at a local electronics supplier or audio store.

I've found this iso to be a good value for my lab bench, when restoring antique radios. Price was right and it's preventing me from being electrocuted.
