Free bump!
I have 2 of those! The first one had an accident, I couldn't wait for the repair and had to get another one! None is for sale though, I am happy not having to carry this huge case in the night train anymore...
It kinds of fills the gap between electric bass and upright, but in a quite different way than my Godin A5 fretless does, both physically and sonically.

PS: you can also get the Rotos TRU BASS in extended lenght to avoid having the golden silk over the fretboard: RS 88EL (XL)
