I just got back from Guitar Center a few hours ago. I played both the LPJ (2013) and the Studio (2014). I wanted to try and get the LPJ because that's the only one that's fairly new where you can get it in white, but honestly, I can't handle the thicker neck. One, because I'm not used to it. But an even bigger reason, as you get down to the higher notes, it's just too thick to be comfortable.
So I played the 2014 Studio, and it's awesome! They don't make it in white, so I wanted black but they didn't have one in the store. So they ordered a black one for me. I did notice that the frets kind of feel too high, so you feel bumps when you slide around on the neck. But they said their tech could file those down a bit. Hopefully that wouldn't mess with the intonation or something??
