I think it should have four strings for some songs but five for others, so we need a Low B that can sink into the fingerboard and lie flush when not needed. In similar vein, and pre-empting the fretted -v- fretless discussion, it needs to be both of course. That clever design which used to get posted every few months, the one where the frets can sink into the fingerboard and lie flush when not needed, would be ideal.
As to pickups, it needs both one and two. So what we need is a pickup design which can sink into the fingerboard ... oh no ... wait ...
