Here's an older RG 5X0 I've had for about 5 or 6 years. It's a 570 body with a 550 neck. The finish is sort of a matte something-or-other, and the pickups were a TZ, FS-1, AN, but I swapped the TZ and AN for a set of Santanas and I actually really love the way this thing sounds now.
That is seriously fucking awesome. I've never seen/heard of that model before.
