Hi mate, for fault finding purposes go ahead and lift the ground: do a positive elimination test, just don't leave it that way. I mean, it isn't an instant death scenario...

If you prove that it is the ground, all you need to do then is identify a ground in the signal chain that you can open and all should be well.

Until you do the test you are groping in the dark.

To all: Remember I said the noise consisted of static and a whine? FWIW, the whine is pitched at B above E on the first string of my guitar. The static is affected by my Bluetooth mouse. I'll have to get a USB mouse to see whether that's it.

I had a quick look at a frequency chart and it turns out that B1 is 62 Hz. That makes ALL B's a multiple of 62Hz which is VERY close to the 60Hz US power oscillates at. Reckon you've proven a mains connection for your noise mate.

The fact your mouse has an impact on the noise also suggests your PC is the most likely culprit - not surprising since there are sooo many sources of electrical noise inside a PC.

You're only paranoid if you're wrong!
