I just re-read my post...I wasn't trying to insinuate that the Zerostat was a sort of black magic. I've actually never seen one in action.
I was pointing to my own crazy theory. It's like that static brush with the grounding cable. Noise reduction market for records seems to attract a lot of "gizmos" or snake oils, I think my neon wand would fall in that category. It charges the dust and makes it jump off the record like reverse polarity. Can't be proved or disproved, order now!
