Thank you everyone for comments and suggestions.
I actually had a solid body Kala U-bass which has been now discontinued. I agree it has great tone but also a few drawbacks; on mine intonation was acceptable only up to the 5th fret excluding the G string which never sounded right to me. It takes time to get used to rubber strings and a miniature fretboard. And last but not least, this bass had a big sound but looked like a toy so it's not appropriate for someone who takes their stage presence seriously
.
So I'll probably opt for a slightly bigger guitar.
