Hmmm,indeed they are there.That was the 1991 Monsters of Rock show with Metallica and AC/DC (not Pantera's rig perhaps). Maybe some kind of logistical thing, being in Russia and all.
Daryll won a Randall RG100H in a guitar contest (very soon after winning his 'original' ML which he sold and got back later in it's Lightning Bolt/Bill Lawrence state) as a teenager. He used this to record CFH (also I believe, 'Metal Magic','Projects in the Jungle', 'I am the Night' and 'Power Metal') he then used a Randall Century 200 for VDOP but went back to his RG100H for TGST. He then returned to the C200 until Randall designed his Warheads for him.
He did use a Marshall Micro Stack (heavily, 'Dimeafied') on 'Living Through Me (Hells Wraith)' off of TGST. But I know of NO other instance were Daryll used Marshall in any 'personal choice' situation.
