If You Play A P-90 Or Another Single Coil Guitar.....

You need this!

It's not a noise gate and I'm not sure exactly how it works (Might have to take a peek inside.) but it gets rid of 99% of any hum from your pickups. Best place to use it is in front of the amp, I use the effects loop for all my time based effects, so my front end goes like this, guitar>Morley Wah>Fultone Fat Boost>MXR Distortion III > Boss TU-2 Tuner> Hum Debugger> Bogner.

So, unlike a noise gate, there is no hum while you play (like there is with a noise gate.) No cut off, just sheer guitar tone. I'm stunned!

Reeeeeeeeeallly?????? no way -----

sound clip! --- I say SOUND CLIP time -------thats a mighty tall claim MR Weasel, Sir, Esq.--llc--Inc-- MD--WADR--- w/cheese........Sir......

will this work for ANY single coil----say perhaps --- a BASS? with a HUMMMMMIE single coil??? hhhhmmm?????

Just a note to consider...

The Hum Debugger and shielding work on completely different principles.

Shielding attempts to block environmentally-induced hum from sensitive components in the guitar. It has limited value to true single coils, as part of the pickup is still exposed to environmentally-induced noise. I've completely copper-shielded my Strat and still get some hum. Like, I said, this is to be expected. I pretty much knew that the fact that the surfaces of three pickups were still exposed to the environment would mean that I was, at most, shielding the controls and internal wiring. But, I was curious as to how much of a difference this would make.

The Hum Debugger, on the other hand, essentially attempts to notch out the offending frequencies from your guitar signal, which will be the fundamental and the harmonics of power line frequency.

How does it behave when you attempt pinch harmonics or natural harmonics?

Maybe just a 60hz notch filter?

That's what it seems to be. But, from searching the Webs, there seems to be pretty scant technical info. One person on another forum noticed this pedal does not use batteries and uses an AC to AC power converter, not an AC to DC converter. The power converter simply reduces the voltage to 7.5 VAC. The thought this person had is that the pedal uses the line frequency, as sampled from the 7.5 VAC supply, as a reference point to create notch filtering for that frequency (nominally 60 Hz), and the next few harmonics, i.e. 120 Hertz, 180 Hz, 240 Hz, etc.

This makes very good sense and would make the pedal effective even if there was some minor drift of the line supply from 60 Hz.

I would never - intentionally - use any single coil pickup unless a producer demanded it and I have only seen a single coil edict in the country music and worship music genre.

And, even then, I can recall the engineer telling me to walk around the studio at Buck's in Bakersfueld (with a Telecaster) until the hum was diminished, then stand in that spot and track a guitar part.

That tells me it was more RFI/EMI than 60 cycle hum.

I do have vintage DiMarzio hum canceling single coils in my old 1987 Squirecaster and they are dead quiet and still sound like a Stratocaster when played clean.

Why make life difficult???

God's way of telling you not to mess with it. Same reason snakes rattle.

I work alongside some really talented musicians and I wonder why anyone would tolerate a hum and buzz from an instrument, even to the point of cultivating it - as some kind of badge of honor - as if the buzz was bestowed upon them by Leo himself, or a demonic angel.

I've heard engineers tell a guitarist to put a Telecaster back in the case because it was just intolerable in a studio environment boring company time...
