Worked. Thanks.

I only have the 50kg option of my combo amp though.

Does anyone know a cable/connector device that does the same? Perhaps a preamp that is actually earthed for cheap if not?

One thing to check with products like this is that the ground is directly connected. Some have a high value resistor between the ground pin and the terminal as they're often intended to reduce static rather than as a direct ground connection.

Indeed. The product in that review provides a solid ground, and I reviewed it because that is unusual. Most are intended for static protection and include a high value resistor, as you rightly say.

If that's just a connection straight to ground, why not just rewire a standard UK plug with a TRS cable? It seems like there's the same work either way (or in fact no soldering with most plugs). (Or will I die as a result lol)

The Groundology plug has non-conductive line and neutral pins, making it inherently safe under all conditions.

Wiring a ground lead into the earth pin of a standard mains plug would do the same thing but isn't inherently safe... And hence it's not an approach I can openly recommend on a public forum to people of unknown technical competence. But I do have some equipment here wired to ground using that kind of technique....

Found out the studiospares valve preamp sells to next to nothing used...and has a ground pin. so should earth everything (and hopefully be useful for more gain much like OP suggesting). notice its impedance its super high (but engaging phantom lowers it) so might improve ribbons and dynamics a bit too.
