Tell something about the guitar. A lot of pickups are suitable for classic hard rock. Btw I have the VHII in an ash strat and it's fantastic for rock, classic rock, hard rock and even some metal. The RiffRaff will do classic hard rock , so do the Mule and Black Dog. Choiche depends on the type of guitar and used woods. I have Mules in an all mahogany Saint Blues and they rock. I can tell you.
