Have you checked out the sound videos on Tonerider site?
Alnico II might be what you are after as from memory it may have been styled upon original PAF's.
Have used Entwistle Darkstars in my son's Strat copy and find them a bit bright/harsh compared to Tonerider Alnico IV's in the EX-1. TR's are twice the price though and a wildcard might be Artist Bullbucker which is supposed to be a SD clone and from the sound videos, it sounds better IMO and well priced too.
