In the end I did pull the trigger on one. I had it delivered last week but I've not had a great deal of time to get to know it yet. I spent about an hour with it yesterday including a slight adjustment to the factory setup, just a little high for my liking. It's obviously a beautifully put together and finished bass, exactly what you'd expect from a G&L. It's a bit heavier than my Precisions but to me, thats no big deal. But for a £1k+ bass I think it should have come with a hard case and not a pretty cheap gig bag but hey ho.
It would be nice to get the opportunity to play it at volume and not just quiet home noodling but that's not going to be happening anytime soon unfortunately. Even so, its a cracking bass.
