Not sure what you mean with the thumb position, @Happy Jack ... Everything looks to be a righty from the start including the strings anchoring and cutaway.
I do really like it.
It should be a plug'n'play... It's their original 120V transformer inside. Just hoping it has the same colour code wires or that there's a colour code wires chart coming with it.
@6feet7 is wanting to "dirty up" his sound. This is exactly what Bartolini pickups do : "dirty up" the sound as they are really muddy pickups and through an all valves (tubes for the others) SVT on its dedicated 8x10" you'll get the ultimate swine sound that so many people love. And I've had dozens of basses with Bartolini's...
That said, I've always found Delano pickups too polite too.
Nordstrand's are gritty, but not dirty.
EMG's could get harshy, but not dirty.
I like the process a lot, but, because there's always a but, I find that CNC machined instruments tend to always have sharp angles and designs too. They still do a lot of things by hand at Lignum (literarily firewood in Latin, no kidding, but has become wood by extension) which is very good as only a human brain can correct these perfection, yes perfection, issues.
That said, @BassNugget the pickups on this very fretless bass are the Fishman Fluence. 😉

Phil Lynott. 😊
And Dave Brock, Jamie Cullum, Marcel Dadi, Dimebag Darrell, Fred Durst, Isaac Hayes, John Hiatt, Ralf Hütter, Robert Plant, @Dad3353, ...
Without forgetting Emily Brontë and H.P. Lovecraft, who were not musicians, just in case... 😉
Indeed these TRB-P's are just amazing basses, sadly on the heavy side.
That said, not everybody has a bad back. 😉
It will sell very quickly as they are sought after, for some reason. And it's also a really beautiful one !
