I had a similar issue with the frets although on the 60s pau Ferro board. No ends covered in lacquer or glue, but razor sharp frets all the way along the the high E edge. Luckily I bought a file a few weeks before for one of my Jazzmaster' s.I want to love theses guitars ! I got the Vintera modified 50's Telecaster in Daphne blue... and after one week... I'm very happy with the sound... But half happy with craftsmanship. The body is perfect and gorgeous ! The problem is the neck. Frets ends show thick spots of amber lacquer or Glue ? Not sure. And some gap under frets are not filled. I checked with my other Fenders and they are all perfect on that point. Even my Mexican Duo Sonic ! I don't know if I should return it or try to fix it. That means fill the Gap under the Tang on a finished neck and file the end frets to remove that thick stuff.
Philosophical question : should I fix a brand new 1299$ Canadian Fender Guitar or just return it for an exchange (my dealer is willing to send it back to Fender and provide me a new one).
It really sucks that these are getting through quality control at Ensenada. These are supposed to be top end MIM Fender guitars, people shouldn't have to piss around filing frets on upmarket products. Come on Fender if you read these forums and address the issue. You are quick enough to take our money, make the goods up to standard, it's not much to ask?
