Cannon-Salute Marshall Spread — Clean Rhythm & Thick SG Lead
Guitar World identifies Malcolm’s Marshall Super Bass as a defining source for “For Those About to Rock,” set clean and extremely loud for power-amp grind rather than preamp fizz. Angus’s thicker SG lead is reconstructed with a Marshall 2203-family head and no conventional effects; exact song controls are not published, so the settings are approximated from the documented period rig.
