Fender Mustang Bass

New Mustang bass came in with some fret buzz. Not sure if it was sent out like this or maybe in was an ex demo bass but the were a lot of high frets, some of which may have been due to wear around the 5th. The fret wire must be quite soft as they had marks in them from the frets. All levelled up and it plays clean and clear. Does my head in that Fender lacquer over the frets on a maple board, why oh why oh why…
