That´s a 424 in the review on VK. The numbers refer to the number of coils in the pickups. 422 for a HSS configuration and 424 for HSH INSTEAD that we are not talking about single coils and double single coils (i.e humbuckers) but single sized humbuckers and thus quad coil humbuckers or in Kramer/Yo-talk QUADRAIL pickups.
You can find some ended listings on Reverb and eBay and they range between 150 and rougly 300 USD - depending (it seems) on wether or not the guitar is in absolute pristine condition and the seller throws in a luxury guitar case to boot
Practice cures most tone issues.
