Hum Eliminator device and P90's?

lines to balanced. Would this solve P90 hum problem? If so, how would it
work? That is, how would you use it to plug a P90 guitar and play through a
MFX pedal attached to an amp?

No.

Is that because the device would need to be inserted between the pickups
and the input jack? Or am I jut totally off base on this?

Be sure that the outlet you are plugged in to is properly grounded.
Don't play near any electric motors, flourescent lights or dimmer
switches.
Good shielding will help considerably.
Use copper foil for shielding.
They also make shieldng paint to shield the electronics cavity.
And get a good noise gate.

What's your excuse..eh?

If it does what it says: yes. The single coil hum frequenzy is 60Hz.

I'd think you're supposed to plug it in first in the signal chain.

A note on this.
A couple years ago I did some recording in a studio.
The place was top notch, lost of expensive stuff like motorized mixers
etc..
I was using my '69 Stratocaster and I had a nasty hum.
I never noticed much hum before but I figured that the gear I was
playing through was more sensitive.
Then all of a sudden the hum stopped.
Five minutes later it was back.
On and off...it was driving me nuts-er.
I finally figured it out.
Every time the tech went in to the recording room he went through a
coffee room first and turned the light on.
When he came out he turned ot off.
The light was on a dimmer.
That was the cause of the problem.
Look around where you are playing.

Off base because - as the description says - it's "designed to eliminate
60 cycle hum caused by ground loops". The 'CAUSED BY GROUND LOOPS' phrase
is significant here.
The description - at http://tinyurl.com/z27o - goes on to say "AC hum and
noise are almost always caused by a loop antenna effect across signal
lines between two or more pieces of gear".
Now that description's right, in a rack mount audio rig, hum is almost
always caused by ground loops (sometimes called hum loops).
This device is simply a set of eight Baluns in a rack mount case, and
where you're plagued by 60Hz hum caused by hum loops, moving some of your
signal paths from unbalanced to balanced is a good way to solve the
problem.
What it *won't* do is remove any hum that's already present on the
(unbalanced) signal from a single-coil pickup equipped guitar.

Hey, Pat.
With 6 folks, all of us weekend warriors, I can only get a few weekend
nights per month that our personal schedules allow us to play.
That's one more reason - though I never considered it before - that I am
hoping a duo/trio/quartet I am trying to form can fill in the blanks with
earlier hours, more intimate (read "less smoky" venues), and different
styles of music. Not sure where it will go, but I hope to include some
jazz, pop, Irish folk and other styles --- long-term project to be sure.
I'm even beefing up to a full PA a full 12 months earlier than
anticipated such that if this side project files, the PA won't be an
issue. Currently have an 8 channel mixer, 2 Crown power amps (one for
FOH, the other for mains), 6 mics, and 4 monitors so far with hopes to
have everything else I need (31 band EQ, bigger mixer, effects processor,
lightweight decent FOH mains, power filters) acquired piecemeal by this
time next year or earlier.
And even if my side project doesn't fly - or is small enough to not even
require a PA - I'll have a system for my son's band to use and for my
main gigging band to use exclusively for monitors or as an adjunct for
larger venues whould we need it. Plus I'll learn enough to be backup the
other co-founder of Rrelic who also happens to be the onstage sound guy
as well as the 2nd guitarist and vocalist :)-
In short, I've found something other than guitars to hae GAS over :)-
As for my main band, we played last weekend and did the best we ever did.
We're off now 'til Friday night 01/02 when we will play at a new venue
that we've been trying to get into for months. And I'm itchy to play! I
never thought I'd say that given that before a friend (the sound guy) and
I formed this band, I never wanted to play out more than once per month!
I just booked several more gigs this weekend such that we have at least 2
gigs/month through March now and am ready this coming week to try and
book another 2 at a venue that has been on our conquer list since the
beginning.
There are 2 other venues I want to get us into on my side of the tracks
and then want to venture to where the real action is about 20-30 miles
away and start schmoozing around there in search of gigs to get us up to
$600+/night.
You know, this gig hunting thing - schmoozing, getting to know bar
owners/mgrs, playing the negotiating game, getting us into new venues -
it's almost as much fun as playing. I may have been a promoter/booking
mgr in a former life :)-

Great explanation and thanks!
One more question below, please...
How about units that change unbalanced signals to balanced and then feed
that signal into the hum canceller? Any hope there?
Boy, oh boy, should be obvious by now that I miss my P90 archtop (ES-
137P). I got rid fo it due to the humming, but I miss the tone!

I looked into have the pup cavities in that P90-equipped 137P shielded, but
was told by my tech that it would alter the tone so mcuh so that I wouldn't
like it anymore.

Noise gate I had at the time, I miss my P90 tone. Love my 57 classic
humbuckers, bot for blues/rock, nothin' rocks like P90's.

Pat, most every bar we play uses dimmers overhead the stage. We turn them
off though for performance as we have a light system. I know it's the
venues everybody running off the same circuit, fans blasting. I'm just
sorry for my P90 guitar.

Get a skinny wire and connect one end under a screw on the bridge or
output jack on the guitar.
Connect the other end under a screw on the metal of your amp.
Next thing to try is to eliminate anything in your signal chain that
has a preamp.
No effects and keep the gain turned down on your amp.
Pt
Greg D
I can't exist without my MFX preamp!!! And turn the gain down? Pat, whattya
think I'm playin' out there - jazz? :)=

I don't believe that. Besides, you could add the shielding and if
the tone is negatively affected you could remove it. I don't think it
would be, but I also don't think you'd get much noise reduction
either. P90s are noisy, probably one of the reasons they sound so
good.
>Noise gate I had at the time, I miss my P90 tone. Love my 57 classic

Yeah boy! I cope with the noise in my single-coils (Strat & P90s)
by running the amp effects loop through one side of a Behringer
Composer Pro MDX2200 gate/comp/limiter, which I also set up to even
out the volume a little without squashing it completely. I still can
get good dynamics but extremes get leveled out.

That's probably the problem.

parallel to the front of the amp? If it's at an angle you will get more
noise and hum.
