Having ran Bass Gear for eight years, I had the pick for myself of whatever I could afford. In that time, the best fretless I EVER had in the shop was this beauty. I just had to have her, but times change and I'm thinning the herd ahead of a house move.
Hand made by master luthier Umut Dal in April 2015 using his own bridge and pickup design, this light weight hollow bodied bass has a top wood of master grade flamed katalox and katalox fingerboard. It has descrete fretmarkings on the side of the fingerboard. If I needed Umut to make me a replacement now, I suspect it would be at least double what I'm asking for it.
If you are interested in having a truly expressive fretless then you really must try this.
