Dunno what videos you saw or if this is helpful, Daulton, but Court and I both use Peavey amps, not Marshalls. Mine is a JSX and I believe Courtney's is a Valve King. I'm always interested to know about the gear of the bands I like too
Hey Nita there's a website that lists the gear your favorite guitarists use. It's called uberproaudio.com. It even has a list of both Dave Murray and Adrian Smiths gear.
