Re: No creme pickups?
Back in the late '70s, Gibson humbuckers were black. Any time you saw double cream, it told you, "This guy modded his guitar with Dimarzios, so he must care about tone." That kind of supports Larry's idea of the trademark, but 40 years down the road, it just pisses people off.
Similar to Lew, there were couple of iconic guitars that planted the double-cream ideal in my head. They were the earliest Hamer Standards played by Rick Nielsen with Cheap Trick, the sunburst #0000 and the natural maple #0004. Both had double-cream real-deal Gibson PAFs in the bridge position. Eventually, Hamer ran out of old PAFs in the parts drawer and started using DiMarzios. When I wanted my Korean Hamer Sunburst to look like a '70s Hamer, I went out of my way to get a double-cream/zebra set, and NOT buy DiMarzios.
