I see some people here and other Builders use a flat (No radius) fingerboard. How many of you have done this or played one and what do you think of it? I have always built my basses with a 16" radius and like it. The closest thing to flat I have played is Warwick which I think use a 20" radius. I do like the way they feel but has been a while. Tell me if it is better in any way or worst and if building this way what to look out for.
