Aside from those threads, I can say some things about them, because I picked one up used. As far as I know, there are no functional differences between a 2013 and a 2014 model. The earlier ones are matt finish. The newer ones are gloss. Some people have mentioned issues with fit and finish, but that's generally related to the 2013 finish, which has a minimalist quality to it, to be polite. Mine is a 2013, and my only quibbles with it are some weird shaping where the horns meet the neck and what I assume is a wiring issue with the tone pot. It functions similar to a master volume control as well as a tone knob for some reason. Maybe that's just how it is. The bass can be thunderous, as you would expect from a Gibson bass equipped with humbuckers. Pull out the coil taps and it can approach a Fender Jazz bass sound. My brother, who is a dedicated Fender Jazz player found a very familiar sound when he messed with the controls for a little while. It won't ever sound quite like a Jazz, and it won't come close to a P or a Ric, but it is plenty versatile. Balance is more like a Fender than the usual Gibson, meaning that the neck balances well in a more horizontal than vertical attitude. It balances with the headstock up more than the usual Fender, so there's that, if it matters to you. The neck shape is similar to a Jazz as well, so you can tell what it was aimed at when they designed it. I'm amazed at how light weight mine is. I can imagine playing it for hours and hours without any issues. I haven't swapped out the strings, so I only know what it sounds like with rounds on it, but so far, so good. It is different from the usual, and it was far cheaper than a US Fender Jazz bass, so I think it was a great value. That's pretty much it so far. I haven't decided if it has made any of my other bass guitars surplus or not.
