That looks like a fantastic bass, would definitely love to have one.
Can't find any online but going by the price of the fretted version I think it's sadly out of my price range.
I actually just did something that should have been obvious earlier - looked on YouTube for covers of Wherever I Lay My Hat and there are a few on basses with bridge soap bars and even one on a jazz bass and I'm pleasantly surprised with how right they sound.
So maybe I don't need to be so specific and just get a fretless that suits me.
