Interesting thread!
According to BURNS guru 'Dusty Frets' in his review of the BURNS 'Marvin' in Guitarist mag, the original pickups were thus:
'each of the black plastic covers carried the Burns Rez-O-Matic legend, and initially the innards were identical to those found on VOX guitars, but with the lower re-shaped by hand to provide a different appearance.'
I have on at least once used a spare set of Rez-O-Matics in a Strat, with no real change to the sound of the Strat. I dare say that an early set of the early 'Rez-O-Matics' installed in a VOX solid body would revert to sounding like a VOX in the same way. I wonder whether Hank was trying out pickups like that in a Strat before he used the Marvin for recording? Now there's another answer for the 'Atlantis' mystery!
As for changes to a Marquee, I had had both Lace Gold and KinmanCVS-HMS Marvins in that before I sold it on, both of which IMHO did sound better than the 'bar magnet' pickups that the Marquee originally came with. I didn't get to fit original Rez-O-Matics to the Marquee as I had originally intended because the pole spacing was incorrect. My BALDWIN Marvin runs a set of Kinman CVS-HMS Marvin pickups (the BURNS Marvins are as original) and I am very happy with those on that guitar. I do have a couple of sets of pickups spare here. like Lace Calfornia, Fender Tex-Mex and Tonerider Surfari's (not to metion the odd humbucker or two), but I don't have a an immediate use for them at the moment.
However, the best six pole pickups I have (in my opinion) would be the Lace 'Holy Grail's, which I have in the '62 Strat.
Hope that helps
