In classic TB style, everyone will pretty much ignore this post, but it contains the truth.
Pro tip - every bass, aside from those built with invisible fret technology, can develop fret sprout under certain environmental conditions. It has to do with the different expansion and contraction rates of metal and wood along with climate, and absolutely nothing to do with build quality.
Some instruments are more prone to it, and some never develop it. I’ve owned several NYC and MIJ Sadowskys, a Fodera, US Laklands, numerous US Fenders and other brands that had varying degrees of fret sprout. I’m nowhere near alone in this, if all the luthiers I’ve dealt with over the last few decades are correct in saying so.
There’s a good number of reasons why I don’t like modern Fender instruments anymore, but fret sprout isn’t one of them. Disliking an entire brand because of fret sprout is like disliking a brand because there are plastic parts and screws on their offerings.
