Said it before and will say it again, signature models (that above and beyond "being" a Les Paul as such) do nothing for me... In fact, I avoid them always. I don't want some other guitarist's name, insignia, initials, or beat-to-shit road worn look on my ax - I'll do that myself thank you very much.
I have nothing but HUGE respect and admiration for the offerings of Randy Rhoads - he was the one cat that got me into guitar at such a young age - I thought he was incredible... To this day? I still think of him in the ranks of all guitar gods past and present. I just hope Gibson pays his surviving family some decent royalties for this blatant money grab.
Peace,
V.
