I'm new to the fretless world (about 2 years), but now play them almost exclusively. My problem is the difference in dot position between lined and unlined boards is hard to adjust to when changing basses during gigs. I have 2 of each, and find large, visible dots at the intonation point an invaluable tool. On the lined boards, there is little or no line visibility while playing standing, usually accompanied by poor lighting conditions, and complicated by vocals and trying to maintain crowd eye contact. Even playing seated, they are barely visible. I'm just curious why luthiers continue this practice. Perhaps as a part-time performing musician, I should just be better at hitting the intonation spots?
