This Noise Eliminator Won't Affect Your Tone!

Nothing spoils a show the way an incessantly noisy guitar does. Bad power, single-coil pickups, too many people in the club suffering from cell phone addictions — it all adds up, and the result can ruin your sound. Not anymore! Now, there's a way to fight unbearable noise and zap hum right out of your signal chain, with the incredible Hum Debugger from Electro-Harmonix. Better than noise gates that still let noise through with the rest of your signal, and far more accurate than mere noise suppressors that put a nasty dent in your high end, the Electro-Harmonix Hum Debugger obliterates hums and buzzes while leaving your tone intact!

Conquers Noise from Single Coils and More

The Electro Harmonix Hum Debugger is a highly effective solution for eliminating unwanted hum from single coil pickups, such as those found in P-90s and Telecasters. As someone who uses it to overcome hum in a basement with poor wiring, I can attest to its ability to significantly reduce or even completely eliminate hum in my signal chain. I already use a power conditioner, so note that this is a multi-level issue for some folks, but the EHX totally works. I have almost never used the higher setting.

In terms of sound quality, the Hum Debugger is highly transparent and does not color the tone of your instrument. It effectively filters out unwanted hum while preserving the clarity and dynamics of your guitar's sound.

Overall, the Electro Harmonix Hum Debugger is a highly recommended solution for anyone dealing with unwanted hum in their signal chain, especially in environments with poor wiring or high levels of electrical interference. Its effectiveness, simplicity, and transparent sound quality make it an essential tool for any guitarist or bassist looking to achieve a clean and noise-free signal.

One important thing to note when using the Electro Harmonix Humdebugger is that it requires the use of the power supply that comes with it. While it may be tempting to use a generic power supply or daisy-chain it with other pedals, EHX says that doing so can compromise its performance and effectiveness in eliminating unwanted hum.

I like it so much that I even bought a second unit for my son who is off at school to help him overcome his dorm room recording issues with his Stratocaster and Jazzmaster. This thing just works.

Electro-Harmonix Hum Debugger

I have really bad 60 cycle hum in my house. Probably because my house is over 40 years old. Plugged in the Hum Debugger and the hum immediately disappeared with no appreciable change in my Strat's tone. Excellent product that works as advertised, which is becoming rarer and rarer these days. Sweetwater's customer service was excellent as well. They called me the same day I ordered the box and let me know it would be shipping that day. I received the box the next morning. This is how customer service should be done.

Works Great to Manage "Symptom" of a Problem

For some reason, I have major buzzing issues at the house I bought last year. Power company and electricians have been out with no luck at diagnosing it. I think it's EMI in the air being spit out by the transformer 10 feet from my house on the pole. But whatever. I have a buzzing issue, that's the point, and it only happens here at my house. If I take my amp guitar to gigs or to other houses it's dead quiet noise-wise. It's annoying to not be able to play at your own house because the buzzing is so loud it prevents any type of dynamic range in your playing. Noise gates are basically useless with buzzing of this level because you lose the ability to roll your guitar volume off, otherwise it gets gated out.

This pedal is like magic. There is still some buzz in the higher frequencies, but you can easily talk over it. See the linked video for the difference. Keep in mind, I'm dealing with a monstrous buzz.

One thing of note is that while this pedal is great for curing the symptoms, I still have an underlying problem that needs to be addressed as it could potentially be causing damage to my amp in the long run.

TL;DR I've dealt with a lot of buzz but what I have at my house is the worst I've experienced. This pedal pretty much solves it. You lose a little sustain in the process, but it's a trade-off I'm willing to make to be able to once again play at my home.

What Do Our In-house Gear Experts Think?

Charlie Davis

I've always loved single-coil guitars and use a fairly large pedal collection, which has always resulted in a good amount of buzz coming out of my amp. I used the electro-harmonix Hum Debugger last weekend at a gig, and it fixed everything! No hum, buzz, or tone alterations. Even with a fuzz pedal and the soapbars on my Jazzmaster, it was completely silent. If you play single-coil guitars, buy this pedal!

Logan Miller

My P-90 pickups can get unruly, and noise gate pedals remove any hope of sustain. Any time I hear a 60-cycle hum on my guitar, this pedal saves the gig without compromising my tone. I definitely bring the Hum Debugger to every gig in case the hum is just too much. Plus this is a great staple in the studio for working with other guitarists with single-coil guitars.
