Is the equivalent g&l better than the mex tele?
plain and simple,,, yes.
how and why
G&L does build a superior guitar to Fender. Much less comercialized, much higher quality. G&L would go out of business building Fender knock off's if they weren't great. They build a better guitar because they HAVE to.
G&L guitars are what Leo wanted Fender to be, so yes. Get it.
