How A Noise Supressor Works?

Hey I got a gibson les paul and a marshall MG half stack. Now when I use the overdrive channels 1 or 2 with the gain on 10 and the channel volume on 10 It doesn't matter even if I turn the master volume up a little. I get alot of hum out of the amp. If I really crank the master volume then the hum is crazy loud can hear it even in my playing. CLean channel is fine no hums at all. Now I am not using any pedals or effects, just guitar straight to amp.
I am wondering if I buy a boss Noise Supressor pedal will this eliminate at least some or all of that bad hum when I use full overdrive gain and channel volume all the way up as well?

read the question, I said i have massive hum issue was wondering if a noise suppressor will get rid of the hum?
Yep. I use my ISP Decimator for just that purpose.
It's weird I mean i thought Les Pauls with humbucking pick ups were suppose to cancel out the hum, even at high gain overdrive. but if a suppressor will fix this, then I need to get one, the hum is just too loud.
yep and there are 2 pedals from ISP that seem to get pretty good reviews. I went for the cheaper option, b/c I didn't wanna spend over $200 on a noise gate.
Humbuckers don't stop amp hiss or noise from your chain post guitar output.
I put my Decimator in the effects loop, and turn the knob til the hiss is gone. My logic tells me it wouldn't work in front of the amp.
Just wondering are you getting loud hum only on distorted channels? or clean as well?
Yeah that's weird, on my les paul i get no hum on clean, quite a bit of hum on overdrive (but its tollerable) but once i turn the gain on full then its pretty bad, can hear it all over the music. I don't know I think I am gonna try a suppressor pedal. Been seeing lots of demos on youtube and seen one video of a guy who had pretty nasty hum and he got it almost gone with a suppressor pedal. Might be something to look into.
It's the wiring of the house. Short of rewiring the house, nothing but noiseless pickups in all your guitars will stop it. I speak from experience. My last place was like this. I had to face a certain direction with my single coil guitars so i'd get hum.
In my new house, no such issues.
Dimmers are known to induce hum in audio systems.
It can come through on pedals too, unless they are properly shielded. We spent a couple hours troubleshooting my board when I started jammin at a new place pretty recently. Jiggled all the cables and then went through my board piece by piece. Finally figured out it was my flanger. It's the only place it's ever acted up, but the story does have a sorta happy ending. Taking that pedal out of my chain really cleared up my signal and it added a little more zing.
also, if your amp has a 2 prong plug on it, plug it in upside down and see if that helps. i had a wiring issue at my old place and i took a 3 prong plug from my amp, plugged that 3 pronger into an adapter to make it 2 prong, and plugged it in upside down and it took care of the problem for the most part. sounds funny i know...
"Well, you tell him that I don't talk to suckas."
Hey man,
just to reiterate ...
i know you are trying to take opinions from a large sample pool to get all your options
but:
1. the ISP Decimator IS a "noise gate" ... they kinda say it isn't, but if you look, they actually do say it is a gate ... just a fancy noise gate, with some algorithm or something that randomly kills the sound at intervals or ???
Any way. that certainly IS an option ... but know that generally with noise gates, the functionality is that when the sound output from your guitar falls below a certain threshold, the device kills the instrument output signal and replaces it with "nothing". Since your signal has been replaced with "nothing" there is no hum, because the hum is caused by intereference created by your home's AC electricity entering your pickups and then traveling out the output jack and through your guitar cable to the amp. Using an ISP Decimator will work, and apparently they work reasonably darn well, but given that it is SOME sort of gate (possibly one that is always on at intervals) it certainly is affecting your sound in some way as well. I've seen some posts by folks saying it killed the end of their notes, or chopped off their sustain (which, reasonably, is what you would expect from a noise gate, even a really fancy one) ...
2. the problem with 60cycle hum is pretty fundamental. If you look in to it deeper, the issue is AC current itself. It operates at 60 hz (60 cycles per second).
Your pick-up is "picking up" the frequency of the electricity running through your house, right on up to your guitar amplifier. And that dang light.
Didn't you say your amplifier, and several other pieces of equipment, were actually wired through the light socket itself? This is one of those old lights with a socket at the bottom?
Also how old is this house, and is the eletricity even grounded?
Is it a 2 prong outlet?
All these issues would amplify the effects of 60cycle hum in your amazing super-awesome P-90 pickups (i loved mine while i had em) since all these factors play in to more electricity just wantonly floating around for your P-90s to "feed" on.
Pictures on how to shield the guitar can be found here, but the process probably isn't to be taken lightly. You also would want a high quality (well shielded), short (to reduce the length of cable possibly exposed to interference), guitar cable.
You also need to think about all the above metioned (and more) implications of the circuitry in your practice pad, and how best to shield your guitar pickups (and all your expensive equipment) from the nasty unintended consequences of electricity. (like removing the ground pin on your amp, and plugging it in to an ungrounded - 2 prong - outlet, upside down, even
and think one more time about just how "good" that ISP pedal must be in order to strip out the sound of constant interference from the very source of sound in your guitar itself. In other words, there must be some unintended tonal\sonic consequences of stripping out the bad sound right from the very source of your good sound. It can't be too good to be true. Can it?

See?
Typo Man: "Thanks kidz, but remembir, stay in skool!"
Does that Casino have no problems with the pickup selector in the middle position, or just no matter what position, there is no noise? I see where some models of the Epi Casino may have had a reverse wound pickup so that when run together (middle position) they hum cancel, but i don't see anyone saying they don't have hum with theirs (no matter year or model,etc) ... i see a lot of "my casino makes a hum" ... lol ...
I don't think you can put a P90 in a strat without routing out the pickup cavities to fit them ... it would be a project, i think.
You will continue to have P90 hum until you remove your P90s, or start trying to isolate your guitars electric path to it's own grounded circuit, and shielding the body cavity. You can get a good noise gate, and it isn't the worst idea in the world, but ultimately you would prefer to address the source of the noise which is your pickups picking up "loose" electrical current in your guitar's area. Try running a quality 12 or 10 gauge GCFI 3-prong extension cord to a grounded outlet away from a dimmer. Plug your amp in to that. Get quality cable for your guitar. Maybe try killing the light on the dimmer completely and getting a stand lamp ? Gonna have to get to "know" your playing environment.
