To cut a long story short...
I have electrical noise coming through on all of the studio guitar amps. I have removed the hum and hiss but getting rid of the fluorescent lights and dimmers in the 'old' building. This noise has me baffled completely though. Now while I am very good with technology - electronics is not my forte.
I believe it's somehow linked with poor ground and something to do with the old building's wiring and fire alarm...It produces an almost digital whirring sound on every single guitar amp that is used? I have tried using a power distributor with little success. It's making it almost impossible to record as the noise is very loud and always present when powered in the studio.
The building is part of the old school/college which is reasonably new recording studio. Does anyone have any ideas of how to resolve this problem, or more importantly, how to cure it (Without a full re-wire)?
Any advise would be greatly appreciated,
Thanks

It almost sounds like a metronome set at about 110bpm - it's so annoying

I have been off work for a couple of weeks so haven't been able to make a recording of the noise. One thing I did notice was even if I don't plug a guitar amp into the mains and use an output from the Furman Power Conditioner, I still have the same problem...Now I do know it's not the amp because If I power it up in a different building it's fine.
It's a strange one that I get the feeling isn't an easy fix

Is the amount of noise variable?
If yes then I'd see if you can find the source of noise yourself by literally starting with everything off then switching things on one by one.
I have tried using a Furman Power Condition but I still get the same noise no mater what amp I use or what Main socket in this building.

moving the studio/ gear to a different room solved the issue entirely.
I also have a digital clicking sound coming through the monitors in the control room - but I am convinced it's separate to the issue - being either a ground loop or HD issue...
It may be a needle in a haystack to find out what equipment would be interfering though. I will try a test next week and see what happens
