I'm curious as to why you added fret lines. I know these things are totally custom, and whoever ordered it probably wanted it that way, but people should really be discouraged from throwing fret lines on a fretless. While individual notes are in tune on a fretted bass, major 3rds are always slightly sharp. I think Adam Neely, as well as Tony Franklin, have explained this in case you think I'm full of crap. Lines will encourage players who might be new or novice in fretless to play out of tune when doing fingerboard runs. Which brings me to my next question: why is new or novice fretless player ordering or buying a $10,000+ instrument?
