Mine was delivered Friday afternoon. I was really nervous when I saw the single thin box that others have described - it was pretty beat, with some big dents in the corners. The box was still factory stapled; the packing skip was just slid under the flap. Thankfully, everything was fine, no damage to the case or bass. It's a 2010, brand new. The finish is beautiful, I like it much better than expected. It plays perfectly, but I'm sure it will need some adjustment after a few days. Right now the neck has some relief, less than .012" according to my gauge. Frets are perfect and the sound is fantastic.
There are 3 minor flaws I've found. Sadly, it has the same amount of tail lift as the Mapleglo 4003 that I returned. For the price, I can live with this and may replace the bridge in the near future. It also has some excess glue or something where the fingerboard and neck join near the headstock - oddly, there was a small piece of masking tape stuck over this. Again, nothing major. I also noticed that on the back, I can see and feel the joints where the body wings are glued to the neck-through body. Very slight, but noticeable. I don't remember seeing this on the Mapleglo 4003 I tried. Maybe they use a heavier undercoat or sealant on the clear finishes? Has anyone else noticed this and is it something I should be concerned about?
I voted "satisfied" and I think this one's a keeper unless those body joints turn out to be a problem. I would definitely exchange for another MB 4003 if I had to return it. Beautiful bass with a unique sound and feel, and a steal for the price.
