The change I am thinking of was from G&B pickups to SE 245's, and HFS/Vintage and Santana, and just about every SE model. They revamped all the pickups. In 2015 they may have started putting S2 versions in them. I just checked the website and they are listed as 245 "S" pups. It would make sense. They don't have to keep two lines supplied with pickups, they just take the best ones and go with it. So that means the new pickups are the same specs as the S2 American specs. The old ones are still a better pickup than the old G&B's which were just so so. Win either way.
