I'm wondering from you guys who have purchased one of these basses, why you chose one over the other. I've tried all three (only one or two from each maker in a store), and am having a difficult time deciding. The F Bass played the nicest to me, but I liked the sound of the Zon more and the Roscoe even a little more. They all sounded great. I have a fretted Roscoe SKB-3006 and was leaning toward a Roscoe fretless, but now I'm not so sure. I think I want something different. I have a little more time than I anticipated. Hurricanes Frances and Jeanne's eyes passed over my office destroying much of everything in it. Insurance has helped for the most part, but not everything. Therefore, much of my bass money has been eaten by my family and ensuring a roof over our heads. The fruits of the responsibility of marriage and fatherhood is worth it though. Please. Tell me why your fretless bass is better than his (or hers).
