first, Iwas not sure it was RGR580 as I mentioned, it's just my 'best bet' on the RGR580, i never looked at the neck pocket.
why did i bet on 'RGR580' instead of RGR470 or 480 or 570 :
it has direct mounted pickups, which only available on RGR580 series, the RGR470 and RGR480 have pickups rings.
why makes me doubt about it :
it has wizard neck, when RGR580 supposed to have Wizard II neck.
it's not mahogany, i know i, it's kinda light, when RGR580 has mahogany.
everything else just the same:
V6 humbuckers, RTS single
EDGE tremolo in cosmo black
AANJ neck joint
So, I named it RGR 580 DX until someone can show me its true identity.
