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

Would it not be most effective at the end of the chain where it is exposed to the greatest amount of noise from cascading effects???

No.

The Hum Debugger is not a noise filter. It phase-cancels 60 Hz hum and it’s harmonics. You may have some odd results if you try that after effects. The best idea with this pedal is to give the effects as clean a signal as possible to work with, by cancelling hum at the start of the chain.

Some noise in cascading effects can actually pass from pedal to pedal via the power connection. You can see if this is a problem you have by running all your active effects with batteries, as a test. If the cascaded signal quiets down, you can address this by using a good isolated power supply, such as the Voodoo Labs Pedal Power 2 Plus.
 
My engineer and I were discussing this today...a out its potential for use in the studio with noisy, vintage instruments....still have my doubts it would be effective with UHF/VHF RFI, but this would certainly kill a lot of line noise.
 
So, I took this pedal out to a gig tonight....absolutely fantastic!
I played the, extremely hot P90 loaded axe in my avatar for the whole show(around an hour and fifteen minutes), using distortion from the amp, my homebrew muff variant, and Ray’s homebrew FireBomb pedal.
From Floyd, To Metallica, this pedal got the job done....I got stopped after our set by multiple people that were floored by our version of Tool’s “Sober”...lots of clean, to grit, to crushing distortion, and back...in that one...something that I usually select the red SG in my sig pic for...but this was totally doable, thanks to the Hum Debugger. Happiness may be a warm gun to some...but it’s my natural P90 SG tonight for me...

THIS!^^^^^^^^^^^^^
This is what the pedal is designed for, and is effective at doing. Plain and simple.
Just like the title of the thread mentions P90s....this pedal effectively chases down 60 cycle hum.
It does it well.
Used with a properly set noise gate, you couldn’t tell my amp was on...never mind on about 7 on the master, with a muff variant set to kill, and some other kind of booster engaged....

Until I lifted my picking hand from muting the strings, and started picking.

That’s what it does.
 
Don,

I’ve read some reviews that say you can get an odd, subtle,metallic tone from the pedal. Have you noticed this?
Not yet. I’ve been prepping for last nights gig, mostly. I had the pedal set to the lower setting for the entire gig, and noticed no artifacts(and I heard myself loud and clear the whole time).
But, to be honest, I haven’t done a lot with it set to it’s high setting. I haven’t needed to.
Now that I’m going to have a bit of time this week...I’ll dig in, and see what I can put together.
I know that when I did flip the switch to the higher setting, I could tell it was doing something...so I flipped it back, liked it there, and went on with enjoying my P90s.
 
been playing p90 into Fender Reverb pro today..turned off the RAT...before i knew half hour went by..there is such a characteristic to them..its very unique..it sorta seems to snarl? cant quire explain it but its a tone ..even in the chords picked clean each note..some kinda attitude is always being expressed...been sliding single notes..it almost invites a natural slide with them without the slide..the tone follows the slide note something extra is just there. So many sounds between 5 on guitar volume and diming it. Was blown away by the instant Sabbath sound..The SG with p90's got to be awesome !!

I'm very interested in this. Even though I always get compliments on how quiet my rig is, I'm excited to think it could be even quieter.

Can you give me dimensions??? Im thinking to mount it under the board upside down...Thanks for the report!!!

In all honesty, I’m betting your new Jr is pretty kick a$$!
Something about those single pickup slabs that makes them magical.
That said, I like having a neck pickup too. :cool: (y)

it is used on song South was on that for main part, SG faded here & there. on fills I do look for the neck pup at times...a lil less bite---creamy maybe..that would be cool !! that LPJ..first riff i played on it..i just had to was brain Stew by greenday..i have no idea what it was played on but into my 74 Super with Rat was that & instant sabbath. am like..i am not even in the Marshall yet & its giving up this kinda tone...sorta hard to put down..1 knob to ride for simplistic tone
 
My front end goes like this, guitar Gibson Les Paul Special)> Boss TU-2 Tuner> Morley Wah>MXR Distortion III>MXR 6 Band EQ> E-H Hum Debugger> Line 6 G-50 or an older Sennheiser Wireless> Front End of the Bogner 20th Anniversary Amp.

The Hum Debugger eliminates any noise from the pedals, I tried it at the front of the line, but I prefer it at the end. I have never noticed any odd metallic noises what so ever.

All my time based effects go through the FX Loop.

That’s good to know!

Just for clarity, though, it seems the Debugger is still toward the beginning to middle of your chain as it is still prior to your FX loop pedals?

I have a kind of split set up. Wah, Tuner, EQ, Distortion go to the main input on the amp along with the Hum Debugger. All my modulation and time based effects go directly through the FX loop. The EQ and Distortion are noisy, the Debugger kills the pedal noise and the noise created by the P-90's. I can crank the volume up high on the amp with no noise (other than the actual amp noise.) with total confidence that the Debugger will eliminate the P-90 and pedal noise.

Does it sound like the pedal noise is a 60 cycle hum (or one of it’s harmonics)?
