From instructions: “Not a noise gate and not a suppressor.”

The hum debugger eliminates the typical electrical hum (40/50/60Hz) that specially with strat or tele or other single coil guitars causes troubles with high gain amps or distortion pedals at high volume/gain.
If you want eliminate noise (hum/hiss) totally, you need an isp decimator or similar. They work differently, with a db threshold, instead the hum debugger simply eliminates that frequency range of the electrical hum, a frequency that is lower than the natural frequencies of an electric guitar (this means that you don’t lose anything).

Thanks!

I love chickenheads, I have owned many other EHX pedals and for chickenheads the best was the english muff’n, here is a photo
