I got it, at one place, on one string on my fretless.
I scraped the varnish (maple fingerboard) with the edge of a scalpel two ro three times, about 1/2" down from where I was fingering the note and the effect disappeared.
It was a tiny high spot.
It may have a series resistor in it for some unspecified reason, 100 ohms would stop a multimeter showing continuity but barely reduce the signal.
Or it could just be a dodgy joint...
Just heard a version of Forever Man that wasn't insipid on Planet Rock, in fact it was brilliant. Turned out to be alive version with Steve Winwood.
LOL!
Bernard has just said exactly that, how much better it is than the original!
It's dated November 18, so I wrote it October 18.
The difference between Mitutoyo and the cheap M&W is like between an 80s MIJ Fender and a CBS one 😉
The Machine DRO one is a Harley Benton or Squier 🙂
I've got a Mitutoyo and a Moore and Wright.
I've also got Aldi and have and have had various other cheap ones.
The Mitutoyo is a joy to use, beautifully finished and the batteries last longer and it remembers its setting when turned off for months.
As for accuracy, as long as you have one that reads to the precision you require and you remember to zero it before use (cheap ones drift with temperature) they all work well enough for woodwork!
<Edit> I wrote a review - I've found it online:

" I have only ever seen one other ‘active’ Jaguar (VM) for sale, it was a few months ago from Japan for £650 plus of course import tax. "
What about this one currently at £64... "dodgy electrics":

Stainless steel is generally pretty difficult to work fro all sorts of reasons.
Back in the days nickel was probably a more practical material.
Today people think anything 'old' like alnico magnets instead of neodymium or ceramic must be better.
Actually it's just different.
That said I'm still loving the nickle strings that my Fender Jazz came with and I'll replace with the same.
For my other basses stainless Rotos (the marmite strings) or Elites.
