    im just wondering if anyone here uses/has used a hum debugger. ive got a load of pedals going into my amp and loads coming in/out of the effects loop so im just wondering if the hum debugger would help to cut out all the noise from the pedals-mostly for when im recording really as you can hear it on the recorded guitar parts and its very annoying

    I’ve never heard of a hum debugger but it sounds interesting, however another way you can do this is by using software after it’s recorded. Most recording software now offers their own version of digital noise reduction which can be used to remove hum. I’ve used the digital noise reduction in both Sound Forge and Adobe Audition and have gotten good results in removing consistent noise like hum.

    I had a hum debugger for a couple of days but got rid of it. It doesn’t really do anything to remove noise out of chain (I’d try the ISP Decimator or the Boss NS-2). I’m not quite sure what it’s use is…

    yes for exce3sive noise i would get a noise gate, unfortunately the last one EH made is long out of production and wasn’t that good IMO (“The Silencer” i still own 2 of them)

    i would also recommend the ISP decimator, it seems to be the best you can get these days.

    the hum debugger is only for removing cycle hum from single coil pickups, the slight noise that you dont get with humbuckers, because they cancel the noise out themselves.

    Before buying a noise gate or such… have you tried a power supply like a power brick (several outputs in paralel, not in daisy chain).

    I had a horrible problem with both HUM and HISS. When I bought a SKB Stage Five pedal board … guess what. Even my Big Muff is dead quite (Apart from the noise I intentionally make when playin with it!!! :) )

    Another thing to analyze is your guitar’s shielding (That would have a considerable impact on HUM)

    Good luck and post your experiment results here!!!

    Cheers.

    most of the hum comes from the power supply actually(thats just what from my experience)

    The morley DC brick is not an isolated power supply, therefore you will still get a lot of noise/”hum”

    when i was using my DC brick(2 of them actually) there was a serious amount of noise. I bought a Humdebugger and returned the next day for a MXR smart gate.

    Now i run two of those in my amps effects loop and in front of the amp.
    The Humdebugger honestly isnt for noisy pedals, more for noisy guitars. you should look into buying a noise gate.

    Should really try with power suppy options before buying a noise gate type thing!

    Again, as I said… after I got my SKB-55 powered pedal board… absolutely no hum nor hiss!!! (And I had it really bad before)

    If the morley power brick doesn’t do the trick… oh well… look for some other brand and model.

    There’s plenty of brands making them: Voodoo Labs, Dunlop, Gator, EFX, SKB (Pedal Board)…

    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).

    If your getting an actual hum from your guitar, the hum debuggers the way to go. If you turn the volume knob on your guitar off and still get it, I’d look elsewhere. I recently had a bad noise issue due to two of my EHX pedals not liking two 9v adapters I was using, fixed it by using the EHX 9.6v adapters.

    I know this is an old thread, but just wanted to post my info incase it helps someone doing searches.
