The Electromatic Pro-Jets have mini humbuckers.
The professional (Japanese) models such as the Duo Jet, Power Jet, Billy-Bo etc. have Filtertrons.
Filtertrons have a very unique tone and can't be compared to mini humbuckers.
My personal opinion about TV Jones Powertrons is that they actually have more of a P90 thing going than PAF.
Jack white has several Gretsches and some ghost build ones. The White Billy Bo, seen in the Bond theme, has Powertrons. The copper triple Jet has TV Jones classic Filtertrons, AFAIK. Then he has a vintage White Penguin with vintage Filtertrons.
Just like AC/DC's Malcolm Young, you don't need high output and lots of overdrive to get that raw tone.
