The RG6-CST is a pretty limited run. Technically, there's no way to verify it for sure, but they pop up for sale very infrequently (maybe 1-2 per year), so there clearly aren't too many of them.
I owned one for a while, traded it for a PRS, and am still kicking myself for it to this day. I think it was the best-sounding guitar I've ever played... the combination of the mahogany w/ the swamp ash top gave it a warmth & smoothness that few guitars have. The neck, though thick, was also one of the best necks I've ever played. Overall, one of the most solid-feeling guitars I've ever had.
