I know that this thread's getting derailed in terms of your requested custom options etc but, if the ACG was and still is your choice in terms of woods and specification I suspect Alan could get it up and running in less time that any luthier would build from scratch and the laquer issue would be firmly resolved.
I think you'll struggle to do any better at any price. I particlarly love the side (sandwich) view of this bass, phenominal!
Nope, I'd put my dosh with Alan every time, even in answer to your original question (so this isn't completely irrelevant). Great pre amp too.
