Since I've moved to uni, I've noticed my guitar makes an annoying, noisy buzz that I've never found before. It tends to go away if I turn down the tone controls, but then of course the guitar sounds like mud.
I was wondering if it was the lighting here, but I tried again this morning with the lights off and it's still there.
So... any thoughts on what's causing the hum? The two things that spring to mind are bad grounding (hope not) or just a higher level of noise that shows up through my poor quality shielding job. Any other ideas?
That wouldn't be Surrey Uni would it? I've played there a couple of times.
As for the mystery hum, I've had it from electrics in the walls, but I should imagine the shielding should sort that sort of thing. Of course, cables and pedals can pick noise up too. I'm sure someone with a better idea will be along soon...

Do you have any idea as to the frequencies (or notes if one prefers) picked up?
Not entirely sure, but it seems to be something between low F and F#. Guess it's not the mains then... I have my laptop and phone charger in the same room, but they're switched off when I'm guitaring. It's more noticeable through my effects pedal (Zoom 606) but that's always picked up a little bit of hum.
Does the noise vary as the guitar's attitude (spatial orientation) is varied. Is the noise constant or time of day dependent?
Seems pretty constant from what I've found.
Is your room located above a high energy physics research lab?
Humm... so that's what the guy on the ground floor's been up to...
I may have to and redo my shielding job anyway- last time I made a fairly rough job of it, and theres a few holes in it here and there that probably don't help things. I used aluminium foil last time, is any other material better?
