Help
Is the the 50/60 cycle hum you here so much about
It seriously gets right on my nerves as causes issue for recording and is ditracting for practice, sometimes it's there sometimes not. I can't track it down to anything in my house. Sometimes I think it's when the washing machine is on
A few points:
1) Happens with any of my amps and any guitars (mainly using Gibson LPs at mo and it's worse on neck pickup on all 3 LPs, which are all wired slightly differently). It's not the guitaras no grounding when touching metal parts, and so far tried 6 out of my 12 instruments.
2) Happens with or without pedalboard (which is curently daisy chained with a one spot - new ISOLATED supply on way). Clean channel not an issue, Drive channels or Dist pedals in front of amp are the problem, pedals worse than drive channel.
3) In this case it's Wampler Pinnacle (powered with one spot) into L6 DT25 Clean channel.
4) This is my little little music room, so gear can't move or be used elsewhere, i't's a small room. New wiring as part of extension. So is there anything I can plug amps/pedalboard into that will clean power if it is the cause of the noise. A special extension cable or something.
5) Computer/LED Monitors/Studio speaker monitors are off are off and unplugged so make no difference. Could it be magnets in Yamaha studio monitors?
6) Lights are LED not halogen in this part of the house
7) Please listen to end and you see how it it stops for a bit, I'm not touching anything
Any ideas at all?
Cheers in advance everyone

A couple of things discovered:
1) The plugs in the music room are on the same same breaker as the kitchen plugs
2) It's at it's worse when the washing machine is on
3) I've turned off every other breaker aprtfrom the kitchen socket inc lights, other sockets etc and it's the same
4) No dimmers
5) Tried loads of leads
6) Straight into amps (3 of them is the same) with any lead is the same with any of 12 guitars
Over on the guitarnerds (run by some current/former guys from GAK) facebook forum it's beem suggested to try a power conditioner like Furman by a knowledgable guy that tours frequently as it could be dirty power!
That is not a general 50Hz mains hum! There is a 50Hz component in it but it is being produced by some sort of machine.
Diathermy? Do you live near a vet? Can you give a general post code? I am for instance NN5 5P* then I can look on Google for possible interfering sites.
I would also post this over at www.soundonsound.com because there are several graduate electrical engineers there as well as guys that do big PA rigs (often the same guy!) ....SOMEBODY will know what that is, Betcha!

Yeah it's definately worse when washing machine is on and the psockets are on the same circuit as the kitchen plugs.
I'll look at soundonsound when I get home tonight
Thanks for that

@BigMonka yep it's an electric line and I'm 0.6miles away from the line and a small unmanned station
@Rocker no ground spike, I'm gonna moving stuff later when home

Are you one of the few people left with overhead electricity supply?
If so that could be tricky to solve. If not look in the meter cupboard and see if your earth is bonded properly to the incoming armour. But TOUCH NOTHING!
You will probably have the neutral similarly bonded (PME) but different suppliers have other arrangements.

I STRONGLY suggest you get a sparks in ASAP. You may have lost an earth (or a neutral). You might have an appliance with a serious earth leak, yes, if you have a consumer unit with an RCD it should trip but ***t'appen.
Do you own a multimeter? If so check everything involved including amps for earth pin to chassis continuity. I know a DMM is not the proper tool for such low resistances but view anything over 2 Ohms with deep suspicion.
