In December 2013 I went into Absolute Music in Poole and bought a new 2013 US Standard Fender Jazz that they had there in stock - I didn't really think too much about it at the time, it was pretty nice and was probably the best Jazz Bass they had in there in my opinion - then I sold it last month and really started to miss it. Thankfully, I've since been able to buy it back from the gent that bought it from me...
Anyway, I went back into Absolute Music this morning just to have a look around and they have three brand new US Standard Fender Jazz Basses in stock, a sunburst exactly like mine, a white one and a red one. Truthfully, none of them are a patch on the one I've got. I really can't believe that the differences between the basses could be so vast considering they are all the same models! Massive, massive contrast.
In short, I'd suggest either looking and trying as many basses as you can until you find a beauty or, as others have said, contact ACG or another custom builder.
Nice problem to have though - deciding where to spend £1500.
