I also recently bought a Barker, and IMO there is a fair amount of confusion by non-Barker players about what the bass can, and can not, do.
For me, the Barker is a bass in it's own unique category. It is most definitely not a DB or EUB, simply on the basis of the scale length and inability to be bowed. It is also not an electric bass guitar, primarily due to the physical configuration of the instrument.
But what the Barker is, as far as I'm concerned, is an absolute tone monster. The chambered body creates a resonance that somewhat emulates a DB, but with a clear EB sound. The tone is deep and definitive, yet it maintains a crispness and clarity that gives you that big punch in the chest.
It seems that players keep trying to pidgeon-hole the Barker into either the EB or DB category, and IMO it doesn't belong in either place. You really have to play it to fully understand what it does and how it sounds. It is quite different and really unique ....
