I absolutely love this bass. I could do without the fret lines, but I don't really mind fret lines in general, especially if they are wood. What I strongly dislike is that the fret lines are seemingly plastic. It's hard to tell, but they are definitely not wood. They seem to be black plastic, possibly nylon, definitely a polymer of some sort. Having played this bass A TON, these plastic fret lines have caused an issue to arise. The rosewood wears down (and yes I'm using the recommended flat wound strings) at a much faster rate than the plastic fret lines. I am now able to feel the plastic fret lines as ridges in the fretboard as I play. I find that to be quite annoying. What's even worse is that the wood in an area up the neck under the g-string is worn quite a bit more than the rest of the neck, so the plastic fret lines in that area protrude from the fretboard even more. This is actually causing the fret lines to begin to perform the same function as an actual fret!!! I physically can no longer play the quarter tones in between the fret lines in that area of the neck on the g-string. Also, sliding up the g-string in that area doesn't sound like a smooth fretless slide, it sounds almost as if there are frets. Trying to play the notes on the protruding fret lines in that area of the neck results in buzzing, muted, unclear notes, as opposed to the nice, clear, specific notes that were produced when I first purchased this bass barely 7 months ago. I am going to plane the entire neck with sandpaper and a 12" radius block. I am the going to seal the entire neck by coating it with multiple thin layers of thin cyanoacrylate (super glue). I'll sand the neck with finer levels of grit sandpaper, using the 12" radius block as I go. Finally, once it's all dried, cured and hard I'll give it a good buffing to make it shine like glass. I know this will result in a change in the sound of the instrument, but I am actually looking forward to that!
