Detail 01
Hum eliminator, not a noise gate
Targets the steady electrical buzz itself rather than muting the signal between notes, so sustain stays intact.

Electro-HarmonixXO Hum Debugger Hum Eliminator Guitar Effects Pedal
Independent shopping perspective
The Korena take
A single-purpose pedal that strips hum from a guitar signal. For players fighting buzz from single-coils, dimmers, or bad venue power.
Strong match
Who this is for
- Single-coil rigs that buzz on stage under lighting rigs
- Recording sessions where hum ruins otherwise good takes
- Players with high-gain amp settings that amplify existing noise
Consider the trade-offs
When to look elsewhere
- Players wanting a noise gate for amp hiss and picking noise
- Anyone whose noise comes from cable or pedal faults
- Minimal-pedalboard players unwilling to spend $160 on cleanup
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Always-on processing when engaged
It works on the signal continuously, so placement in the chain changes how much noise it catches.
Detail 03
Effects pedal format
Sits on the board with your other pedals instead of requiring a rack or amp modification.
Detail 04
Electro-Harmonix XO series enclosure
Standard compact pedal footprint, so it fits normal pedalboard layouts and power setups.
Detail 05
$161.50 for one job
Costs about as much as a mid-tier overdrive but only solves hum, so it earns its spot on noisy rigs.
Final check
Know before you order
- 01Power supply is a separate purchase; check your board has a free output
- 02Try it early in the chain, before gain pedals, for best results
- 03It will not fix hum caused by a bad cable or ground loop in your amp
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this remove all pedal noise?
No. It targets electrical hum. Hiss from high-gain pedals, fizz, and picking noise are different problems and need a noise gate instead.
02Where does it go in my signal chain?
Early, before your gain pedals, so it cleans the signal before distortion amplifies the hum along with everything else.
03Will it work with humbuckers?
Yes, but humbuckers already cancel much of this noise. The gain is biggest on single-coil guitars, which is where hum is worst.
04Does it affect my tone when engaged?
It processes the signal continuously while on, so A/B it with your rig before committing it to the board permanently.
