Demo of a brutal Marshall Randy Rhoads Full Stack with a 1973 Gibson Les Paul Custom (Randy had a 1974 Custom). The Stack, which is a recreation of the stack Randy used with Ozzy Osbourne in the early 1980s, features two Marshall 1960 Lead cabs with G12T-75 Celestions (Randy Used Altec Lansing 417-8H in his 1960 cabs).
The cascaded channel, which is usually on the second input jack is moved to the first input jack on this amp.
