Hum, noise coming thru the power to my house to my amps.

[Gsxrbusa]

I am getting a hum mixed with a white noise coming thru my speakers when on clean or lead channels. It sounds like the ocean is coming thru my speakers mixed with a hum. I have noticed it on the Peters and Diezel. It started a couple weeks ago and was never there before that. At first I thought it was something in my signal chain, I unplugged everything and went straight into each amp seperately, noise still there. I also moved an amp to a different location in the house using a different speaker cab and cables. Noise still there. I have used multiple outlets with the same outcome. I also noticed that the noise is there when no instrument is plugged in and amp is off standby.

I have eliminated it as being my gear and think it is the house. The house is only 9 years old.

Any help or suggestions would be great. This is really starting to piss me off.

Thanks

Got any light dimmers in your house?

 

[Lord Toneking]

Got a ground stake outside?...with no smaller than #6 AWG copper going to your panel (can be bare or insulated)

Yep, have only one.

Just checked. Yep, all good.

Dimmers can cause a problem... You can opt to buy a studio-grade noiseless dimmer, or just replace the one you have and see if this makes a difference.

Ok, cool. I just removed the dimmer completely.... Noise still there.

Probably have to turn the house off....

In many ways, this is true. I ya REALLY wanna get to the bottom of this, get your amp and cab in a room with as few electrical outlets as possible - turn OFF all the breakers in the home and test your amp. Preferably in a window lit room too, so there's no light on. I'm not joking. If you can get clean from this set up, then start turning one breaker on at a time, and listen to the amp after each throw.

Just my guess and advice. If I were you, and I am nuts (just letting you know) , I would do this

My curiosity would kill me

I get that from TVs in the house. Once they're off it is much better.

Yeah.......shit is driving me nuts. It never did this until recently.

I am just as nuts about noise that should not be there. I think I will start shutting off breakers, one at a time, to see if it ever goes away. That is a good idea At this point I am half tempted to run an extension cord from my neighbors house to see if his power is clean.

The thing is....nothing has changed. No new TV's or anything like that. The noise just magicaly appeared one day. Freakin weird.

Have we explored the V1 preamp tube and the PI tube??

Maybe a stoopid question (BOO stoopid questions!!) but sometime them obvious things ain't so obvious

Check the wall voltage?

Just checked it. 121.7 V to 122.0 V at various locations through out the house.

I would actually recommend checking this as well. In my Wizard running Tungsol pres would induce hum even when they were silent in other amps.....if its more than one amp doing it, probably not a tube issue.

Hum could be a ground or the gtr pickups grabbing some nearby RF issue, but not the white noise....that sounds tube related.


Did you try a ground lift adapter on the power cable?

Geo and Ventura, the funny thing is I did find a noisy V1 pre in my Peters that was making this pulsating type noise. I put a new one in and checked the remaining preamp tubes. It solved the throbing noise but all my amps are making the same noise that I described earlier.

I also tried using a Hum X eliminator (basically a ground lift) that I had laying around. No change what so ever. I am positive it's not my amps or guitars because it will make the noise with nothing plugged in the inputs. I am wondering if something in the house has gone south causing noise on the line? I have 2 refridgerators and other normal shit like that. Maybe it's possible something in the house is causing it? Or something coming in from outside on the main line? Tomorrow I will shut down breakers and try and pin point it.

I will report back tomorrow. I recently got a Brace wireless unit and it was unfuckinusable. All it did was magnify my problem. Just need to pinpoint it and I am going to be a freak about it until it is resolved.

Thanks for the ideas/help fellas.

I got the same problem with the electrical at my g.f's house it is basically unusable with any amp
Humx didnt work for me either..

I'd be interested to see how this pans out - hope the breakers scenario works out

Maybe acoustic gtrs are in your future?

I'll though out a bunch of stuff. outlets wired backwards or ground is not actually grounding? PCs, Neon beer lights in the garage, Wireless network or maybe a real close Neighbors wireless, cell and wireless phones. new cell tower in the area, I read one time that a bad power cord turned an amp into a radio. preamp tubes missing Covers? Amp and effects are plugged in to different outlets (causes a ground loop) D.I. going to a PC or P.A. that is plugged into a a diffent outlet. Space heater, humidifier, baby monitor????

I have this issue a few times with bad instrument cables. I am really curious now, Please post when you find the cause.
