It simply appears that G&L contracted a nondescript builder to make nondescript basses so they could offer a cheaper option. I'm sure they are no better, or worse, than any other cheap mass-produced Jazz bass. Production is pretty good on cheap instruments these days.
If you're strapped for cash, and a G&L fan boy, this is the bass for you. It will play and sound, however, just like any other inexpensive J copy.
The name of the series is..... unfortunate. Instead of going for something cool like "Afterburner" they landed on something closer to "Afterbirth".
