Fender bought Charvel back in 2002, they own them............... Many people still don't know this.
The sticker about the authorization of the headstock is more of a warning to others that permission has to be given to use it's likeness. Also keep in mind that although Charvel may have their own "management" team, they still answer directly to Fender Corporate, in-fact, they are in the same building and offices as Fender. And the MIM are made at the same factor, by the same workers as Fender guitars are made. Not exactly separate companies. On paper yes, but the money goes to the same place.
Fender bought Charvel/Jackson to try and get into he super Strat business. Most hard rock, metal, players always gravitated to the super strat over the standard strat. Yes guys do drop Floyds and humbuckers into Fenders, but hey are not the same. So Fender wanted to make money of this segment. Right now the super strat still really isn't popular anymore in mainstream music. So the margins are very thin.
The Price on the Charvels are higher because of Duncan pickups, Floyd tremolos and the fact Charvel/Jackson represents a higher end guitar. Fender parts are much cheaper and many are made buy them, where duncan pickups and a Floyd have a higher markup since other companies profit from this.
I have no problem with the 850-899 price tag, just sucks you have to pull the neck.
