So there is nothing different but the look und the Hipshot bridge, no specific construction details, wood combinations or different pups?
It's basically a Blackbird then. The later Nicki Sixx Signature Bird (i.e. the flamed red one) at least had maple wings which did affect the sound.
BTW, I put the Hipshot bridge on my Blackbird (I wanted to try it on at least one of my TBirds) years ago, so I'm already there.
