"This guitar is Bob's 'version' of Malcolm Young's famous Gretsch which I think was a Jet Firebird. The story is that when the AC/DC were in Vancouver making an album a while ago the pickup broke so Bob introduced Malcolm to a local pickup maker/repairer who sorted it out. As a thank you Malcom let Bob have a version of same pickup and he procured this vintage Gretsch and put said "blessed" pickup in...
I think the pick guard is off an Epiphone or something and it covers the two holes for the missing two other pickups that you will see Malcom removed (as they are useless) as that model Jet Firebird came with three."
