I'm not a mod, but I guess you didn't know we're not supposed to link to active auctions . . .
But to answer your question, that is an RG 520 QSTB (Quilted Sapele Transparent Blue)
It's a mahogony body with a (very) thin Sapele top. Beautiful guitar. In person though you can't see the top as clearly as you can under flash photography. The finish, though "transparent" is quite dark, but under the right lights it's fantastic.
I have one (with Evos) and love it. The one there is even the same year as mine, 1999.
