Mine has a beautifully flamed neck.Those red Sarzo models are really beautiful.
It has helped the open notes speak better, plus improved sustain, punch and intonation . The one design flaw of those basses is the break over the nut, it is usually too shallow for optimum performance. 17 degrees is the magic angle usually.I've never seen string trees added to those basses. I wonder why they didn't do that. Looks ? Do you notice that it "handles turns" better ?
