I just got my new jackson off and its beast . 1st it looked like the one he called concorde i looked at the serial # and it wasn't concorde. I thought it was at 1st. I googled randy rhoads guitars signatures . To be one it had to have RR at the beginning of the serial # . Mine dosen't . Does anyone know what my jackson might be ? I'll try to get pics of it up on profile but I'm really busy so I don't know if I'll get a chance.
