Dude! Thanks for the pics. Are those your guitars? They're awesome!
This is by far the most helpful forum I've ever used!
yeah, my '73 Custom and my recently acquired '78 Greco EG900
I used to be very unflexible when it comes to pickup color combinations
I only liked dual open black or regular matched covers
recently I've been loving almost any usual color mismatched combos
black + cream, black + white, zebra + white, covered + uncovered
I think mismatching gives them quite a personal charm
before finding my black beauty, I spent a year dating an early 70's yellow cream les paul custom on ebay (I think it was an old refinish and didn't have a pickguard), and it that had an open black and an open alpine white humbucker
that was one unique looking guitar (being a common les paul custom) and that totally changed my mind on how a looked at mismatched looking sets
I really desired that thing, but couldn't afford it at the time... it was sold quite cheap (around US$1800) almost a year later and the buyer was some store and that son of a bitch put it back on ebay for like US$4500

I probably have a picture somewhere
edit:
here it is
