As a response to a question on my 'other' forum, I threw together a one take video on that buzzy noise we hear that goes away when we touch the strings. It's the sign of a good ground, not a bad ground.

Thanks as well. I won’t be spending time chasing the inevitable.

This is easily one of the top 5 things we explain on a near daily basis in my shop.
Other things include "no, you guitar needs more than just a 'neck tweak'", "yes, wood movement with humidity is real, even if your guitar was expensive" and "if you play hard, it will buzz". All things that people are likely to resist and need careful explanation. I'm glad to see stuff up on the interwebs that is clear, thorough and accurate!

You’re a handsome feller, too. Awww Leftee, you sweetheart. Your cheque is in the mail. Thanks buddy! My wife tells me often enough that I look pretty good for 47 1/2 years. She may be on to something.

I get the same thing from my wife. Just change the number to 59.

I don't know what it is, but we're doing something right!

In my case I hid my wife’s glasses. Yes, well done with the video! The only improvement that came to mind would be use the word ’gain’ rather than ‘distortion’, as, eg 20dB, of ‘clean’ gain from a compressor or booster will raise the noise floor just the same as it would if it was coming from a distortion pedal. I wonder how much guitar rigs in Amsterdam etc buzz, being as of necessity, they rely on residual current trip devices, rather than a ground connection, for electrical safety?

I thought there would always a ground connection, right? An RCD detects any change difference between the live and neutral and uses that as a shut off. Right? Wrong?

There was some discussion on this over at TGP, having trouble finding it at the moment though. Someone from the Netherlands said as there's so many effectively floating buildings, grounding the electrical installation often isn't feasible, so the risk is managed by having mandatory residual current protection devices on every circuit. Yes, more that a few mA differential between live and neutral, and within a few mS the circuit trips.

Ah, I misunderstood. The lack of ground is not a result of the RCD. Just as in the US, in Europe there are old buildings that have no ground (just two-prong wall sockets) so an RCD makes sense as an additional safety measure. (My impression is that it is much more common in the US). Old buildings in Europe buzz no more than old American buildings. Just at 50Hz instead of 60Hz.
