i don't think there'd be a huge difference. people moan about the mustang all the time, the tuning problems, the pickups, etc.. (not accusing anyone), but the truth is the mustang was never intended to be a pro guitar. surely any pro could buy one and if he's a fender fan is prone to be pleased, but it was marketed as a student guitar after all. i don't think they're meant to be awesome. the squiers of their day, the only reason they're better than squiers is because fender didn't have overseas factories who could mass produce using cheaper materials. plus it was the 60's, jingly jangly beat pop.
