Interesting, I see where the "Corona" Fenders no longer say "Made in the USA" or USA on them anywhere. There's just a simple "Corona, Ca" on the headstock.
Apparently, the US content is not high enough for them to be labeled "USA" anymore. Not that it really matters, the quality from Mexico is getting so good that there's really no reason not to buy a mexican Fender if you simply want a player. My Mexican Tele is better than my USA Tele. So other than paying more, I don't see the difference.
Yes, some Squiers still use ceramic pickups, cheap woods and hardware, but it seems the USA and Mexico Fenders are pretty much using the same parts now.
